Hydrodenitrogenation of indole and quinoline with a nickelous chloride - gaseous hydrochloric acid catalyst system by Thomas Joseph Buller A thesis submitted to the Graduate Faculty in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE in Chemical Engineering Montana State University © Copyright by Thomas Joseph Buller (1973) Abstract: A supported NiCl2- gaseous HC1 catalyst was used in the hydro-denitrogenation reactions of indole, a nonbasic compound, and quinoline, a basic compound. The reactions were carried out at a reactor temperature of 400&deg,C; a reactor pressure of 850 psig; space velocities of 4.0, 1.6, 1.0, and 0.7275 LHSV; a hydrogen rate of 500 SCF/bbl of liquid feed; a chloride to nitrogen content of eight to one; and using p-xylene as the carrier oil. Nitrogen compositions were determined by a Kjeldahl analysis and a Mohr test was used to determine chloride contents. The amine forms of basic and nonbasic nitrogen compounds from indole and quinoline runs were isolated. These compounds were then identified using gas chromatography and mass spectrometry. In this research, nitrogen was found easier to remove from the product oil of quinoline than indole at 4.0 LHSV. However, little difference, was' observed for lower -space velocities. Different reaction mechanisms were proposed for the denitrogenation of indole and quinoline. It appeared that hydrochloride intermediates are present in the reaction sequences and that nitrogen leaves the reaction zone as ammonium chloride. Also, possible limiting steps in the reaction sequences were proposed.

BACKGROUND Indole and quinoline are heterocyclic nitrogen compounds which have been found in fossil fuel stocks. Indole, a nonbasic compound, has been isolated in petroleum crude oil'(28) and in coal tar (3 ). Quinoline, a basic compound, has been identified in crude oil (2k, 28), coal tar (3), and in hydrocracked shale oil (4, 7)• The structure and other signifi­ cant data on both these compounds as well as on other important nitrogen bases and nonbases are presented in Figure I. Nitrogen compounds are' not desirable in fossil fuel stocks. There is now: much evidence to suggest that the nitrogen in fuels is as important as the nitrogen in air in the formation of nitrogen oxides during combus­ tion (.10, 3l). Nitrogen oxides in the presence of sunlight undergo a photochemical reaction with hydrocarbons to form smog. Also, in the petroleum industry, nitrogen is a poison for many catalysts. Its effect is most notably seen in catalytic reforming where nitrogen decreases the isomerization efficiency of dual-functional catalysts (2, 12, 15). Today, with the United States experiencing a domestic shortage of production crude oil, different sources of energy must be found. One potential source is the Green River shale oil formation of Colorado, Utah and Wyoming. It contains an estimated one trillion barrels of oil. However, it also contains 2.k percent nitrogen (?)• Before this oil can be utilized, the nitrogen content must be reduced considerably. Hydrodenitrogenation has been found to be the best way of removing nitrogen from petroleum stocks (12).

These catalysts systems generally denitrogenate nonbasic compounds easier than basic ones (12). Also, most nitrogen from these treatments ends up as ammonia. These systems are also better suited for desulfurization than denitrogenation. This department, in hope of finding a better denitrogenation catalyst system, has been, doing work on a niekelous chloride-gaseous hydrochloric acid catalyst system since 1966 (11,19,20). This work has primarily been aimed at determining, the operating variables for maximum denitrogenation. However, work has also been done to determine the relative ease of denitrogenating a number of heterocyclic nitrogen compounds. 1) This system has shown some unusual characteristics: Basic compounds are generally easier to denitrogenate than nonbasic compounds. 2) There is a higher denitrogenation than desulfurization activity. 3) Hydrochloride intermediates are suspected in the reaction sequence. H) Nitrogen appears to leave the reaction zone as ammonium chloride. The work detailed in this report has been done to find a mechanism to account for these characteristics. B. THEORY In understanding the mechanism proposed in this report, "basicity" - 4 - Pyrrole P Electrons Pyrrole it Clouds Pyridine it Clouds unshared electrons Pyridine P Electrons FIGURE 2: The Electrons in the P Orhitals and u Clouds of Pyrrole and Pyridine - 5 is a very important concept. Generally, heterocyclic compounds are arbitrarily classified as "basic" or "nonbasic" by their ability to react with a perchloric acid-acetic acid solution. Basic compounds can react with this solution and nonbasic compounds can not. The reason for this difference can be found by studying the electronic configurations of the pyrrole and pyridine carbon and nitrogen atoms. As can be seen from Figure I, pyrrole and pyridine are very similar in molecular structure to indole and quinoline respectively. In pyrrole, a nonbasic compound, the electronic configurations the carbon and nitrogen atoms are as follows: Is CARBON (y) 2s g)_o_g, o sp Is NITROGEN 2p 2 hybridization 2s 2p -O O 0,0 sp 2 hybridization - 6 Each carbon and nitrogen atom is bonded to three other atoms by a bonds using the trigonal-planar, sp 2 hybridization orbitals. This leaves one electron in a p orbital for each of the four carbon atoms and two electrons in a p orbital for the nitrogen atom. these six p orbitals gives rise to a of the molecule. cloud above and below the plane it The electrons in the sharred by all five atoms (3). Overlap of it clouds are delocalized and This gives a stabilizing effect to the ring known as an "aromatic sextet." It should be noted that in pyrrole there are no unsharred electrons in the outer valence state. In pyridine, a basic compound, the electronic configuration of the carbon and nitrogen atoms is as follows: CARBON 0 O OQO sp NITROGEN hybridization O ,O O 0,0 sp hybridization As can be seen only the electronic configuration of the nitrogen atom has changed. In pyridine nitrogen in bonded to only two other atoms and - 7 only one electron in a p orbital is needed to complete the aromatic sextet. Therefore, there are two unshared orbital which can be shared with acids (3). orbitals and the tt electrons in the sp 2 The electrons in the p clouds of pyrrole and pyridine are shown in Figure 2. Since the basic or nonbasic classification is an arbitrary one and since some heterocyclic nitrogen nonbases can react with strong acids, a more universal definition of basicity will be used. report, the Lewis theory of basicity will be used. Lewis stated that a base was anything which has an unshared pair of electrons. and quinoline fit this classification. For this Pyridine Lewis also stated that an acid was anything which could attach itself to such a pair of electrons. For instance: + HCl Pyridine Base Pyridine Acid Hydrochloride Pyrrole and indole while not forming salts with even strong acids cannot be considered acids so the classification of "nonbase" will be used for these compounds. II. RESEARCH OBJECTIVES The primary objective of this research was to identify intermediate compounds in the hydrodenitrogenation of indole and quinoline which then could be used to speculate as to possible reaction mechanisms. Other objectives were to prove the existence of. ammonium -chloride and hydro­ chloride intermediates. III. EXPERIMENTAL APPARATUS, PROCEDURE AND ANALYSIS MATERIALS I. Charge Stock The two nitrogen compounds used in this work were indole and quinoline. They were chosen because they are both found in coal tar and crude oil and because they are both available in large quantities, in pure form, and at reasonable prices. The nonbasic compound indole was obtained in reagent grade from the Aldrich Chemical Company. The basic compound quinoline was supplied by the J. T. Baker Chemical Company in reagent grade. The carrier oil initially chosen was "Peneteck" a commercial mineral oil produced by the Pennsylvania Refining Corporation. However, this oil proved to be unuseable since it interfered with some nitrogen peaks on the chromatograph. Therefore, p-xylene, a compound with a retention time less' than the nitrogen compounds was selected. This compound was obtained 99% pure from the Chevron Chemical Company. The charge stock also included methylene chloride and hydrogen. Some of the hydrogen reacted with the methylene chloride to form gaseous hydrochloric acid under the reactor conditions. Hydrogen was supplied in 2000 psig cylinders by H . R. Oxygen Supply of Billings, Montana. The methylene chloride was obtained in reagent grade from the J. T. Baker Chemical Company.

Catalyst and Filler The catalyst used in this work was prepared hy Fedoruk (ll). He impregnated HiClg on a 1/8 hy 1/8 inch Harshaw alumina pellet. He determined the nickel content of the pellets to he 7.72 percent. By using only this catalyst, the nickel content of the pellets was eliminated as a variable in this work. The Norton Company supplied the filler. It consisted of inert alumina pellets and was used to support the catalyst pellets in the' reactor. B. EQUIPMENT A schematic diagram of the equipment is shown in Figure 3. The liquid charge stock was pumped into the top of the reactor by a Lapp diaphragm pump. cylinder. Here the liquid combined with hydrogen from a pressurized The' hydrogen rate was measured on a calibrated. Brooks high- pressure gas rotameter after the hydrogen had been deoxygenated in an Englehard deoxo unit and dehumidified in a molecular seive drying unit. A detailed diagram of the reactor is shown in Figure A pressure gauge which measured the reactor inlet pressure was attached to the top of the reactor. Also attached was a 2000 psig rupture disc - in the event of overpressure this disk would depressurize the charge to the vent system. The reactor was' a schedule 80, corrosion resistant. Inconel alloy pipe 52 inches in length and one inch in diameter. A six inch diameter aluminum block enclosed the upper 60 percent of the pipe. Wrapped - 13 around the block were three heating coils each with a Variac. The middle coil was automatically regulated by a Wheelco Capacitrol onoff controller . Extending down the middle of the reactor as far as the bottom of the aluminum block was a thermowell. One iron-constantan thermocouple measuring a temperature in the middle of the reactor supplied the input signal to the on-off controller. Three other thermocouples connected to a Leeds and Worthrup indicating potentiometer measured the temperature at the t o p , middle and bottom of the reactor. The product after leaving the reactor passed through a Grove back­ pressure regulator and into a flask. The liquid was collected in the flask and the gas first bubbled through a caustic bath to remove the acidic vapors and then was vented. C. OPERATING PROCEDURE I. Process Conditions In order to identify intermediate products from the reactions, the system was operated at less than optimum nitrogen removal conditions. These reduced conditions were: a) The reactor temperature was 400°C. b) The reactor pressure was 850 psig. c) Hydrogen rate was 5000 SCF/BBL of feed.' d) The nitrogen content of the feed was 0.66 percent. e) The chloride to.nitrogen ratio was eight to one. f) Liquid feed pumping rates were 4.0, 1.6, 1.0, and 0.7275 LHSV for-the quinoline runs and 4.0, L. 6 , and 1.0 LHSV for the indole runs. 2. Reactor Charging The 250 ml of filler and 100ml of catalyst used each run were dried at 400°C for 2k hours. These were cooled in a desiccator. In charging the reactor, half of the filler was poured down the inverted pipe with the thermowell already in place. Then the catalyst, followed by the remaining filler, was added. After each layer was in place, the side of the pipe was tapped to insure complete and uniform settling. Finally, a glass-wool plug and a stainless steel coll were positioned to support the catalyst and ■filler as the pipe was turned upright. Then, with the pipe enclosed in an aluminum block, the heating coils were turned on and the reactor was brought up to temperature. 3. Reactor Operation With all fittings tightly sealed and the reactor at ^OO0G , the back-pressure regulator was pressurized to about 825 psig with hydrogen. The reactor itself could then be pressurized to 85O psig inlet pressure-with the selected hydrogen gas flow. for gas leaks, the feed pump was started. After checking By measuring the volumetric feed rate of the oil, the adjustable stroke on the piston pump was set to give the desired space velocity. During the run, the temperatures in the reactor were closely watched and the two manual variacs were adjusted to keep the reactor top and bottom temperatures as close to 400°C as possible. To insure - 15 a completely "lined-out" catalyst, 500 ml of feed were reacted before any product was sampled. After 200 ml of product oil were collected, the reactor was "shut down." This process consisted of shutting off the hydrogen rate, the feed pump, and the heating coils.. Also, the reactor system was depressurized. When the system had cooled, the reactor was emptied and the entire system was cleaned. The catalyst and support were discarded without being reused. hot water and acetone. The reactor tube was washed with With the indole runs material which had accumulated in the bottom of the reactor and on the support coil was also saved for further analysis. D. ANALYTICAL METHODS The nitrogen content of the samples was determined by a standard Kjeldahl method (l8 ), Two analyses of each sample were run and an average of the two analyses was recorded. Kel-paks obtained from Matheson Scientific Company which contained a weighed amount of K^SO^ and HgO proved to be time saving. The chloride content of samples was determined by the Mohr volumetric method (33). The nitrogen compounds in the product samples were separated into basic and nonbasic fractions and then concentrated according to a method outlined by Hartung and others (l4). These concentrates were tentatively identified chromatographically. The unknown concentrates were injected into the chromatograph and the peaks observed were compared for retention time with known compounds. Also, retention data from - 16 Poulson (24) proved to be quite useful. The three columns which proved to be most successful were given in Table I. TABLE I: Chromatographic.

The KOH treatment was applied as outlined by Smith and Radford (26) to reduce severe tailing of the nitrogen compounds which was encoun­ tered on untreated columns. The treatment was very successful. The chromatograph used was a Varian Aerograph 200. The recorder was a Sargent Model SR. The primary tool for identifying the nitrogen compounds was mass spectrometry. Two mass spectrometers were used in this research. One was a Varian Model Ch5 which was located in the Chemistry Depart­ ment of Montana State University, The other was a Variant Model MAT 111 located in the Chemistry Department of the University of Montana. Both analyzed samples which had passed through one of the columns described in Table I. In this way, the samples were separated into individual compounds before they were analyzed - unless two or more compounds had identical retention times. IV. A. RESULTS M D DISCUSSION Nitrogen and Chloride Analyses' After every quinoline or indole run, a white crystaline solid was found deposited on the upper section of the support coil and a large amount of brown solid was found in the bottom of the reactor. Previous workers (ll, 19) felt that the white crystal was probably ammonium chloride. The data in Table 2 confirms their hypothesis. TABLE 2: NITROGEN AND CHLORIDE M L A Y S E S OF WHITE CRYSTAL % N % Cl 1st 26.67 66.76 2nd 27.49 ' 66.21 3rd 26.95 67.64 Average 27.04 66.87 Standard Deviation 0.295 0.510 Actual Value For Ammonium Chloride 26.18 66.28 The slight deviations of the experimental values from the actual values are likely due to small bias in the experimental techniques. Also, ammonium chloride sublimes at 3^0°C at atmospheric pressure and so would be expected to .sublime in the upper section of the cooling portion of the reactor. Previous workers (ll, 19) felt that the brown solid might be hydro­ chloride salts of the basic nitrogen compounds. Data taken in this work supports this hypothesis.- For each of the nine indole runs the nitrogen and - 18 chloride contents of the solid were found. The nine nitrogen analyses showed an average content of 12.67% with a standard deviation of 0.365. The nine chloride analyses showed an average content of 39.46% with a standard deviation of 1.379. Nitrogen and chloride analyses were not run on the solid from the quinoline runs. It must he noted here that nitrogen and chloride analyses were calculated on a different basis. The chloride samples were dried at IlO0C for one hour before being weighed, but the nitrogen samples were not dried. It will be shown later in this report that aniline was identified in both the quinoline and indole runs. Aniline in the presence of hydro­ chloric- acid forms aniline hydrochloride (2l). nitrogen a n d ,27.35% chloride. values. This compound has 10.81% These values are lower than the experimental However, if some ammonium chloride were present in the brown solid and if one takes into account the different basis for the nitrogen and chloride analyses, the experimental values are possible. In the 4.0 and 1.6 LHSV quinoline runs and the 4.0 LHSV indole runs, some of the hydrochloride salt, in the form of a very viscous liquid, flowed into the product flask. The salt did not usually enter the product flask until about 500 mis, of feed had been reacted. The constrictions in the bottom of the reactor and the back-pressure regulator obviously restricted the flow of the salt. Since not all of the salt made it into the product, flask, it was .decided, to,:exclude the salt in the product flask from the samples for nitrogen analysis. This was accomplished by simply decanting the oil product off the very viscous salt.

Introduction Figure 8 is a chromatogram of a known mixture of basic compounds. It shows that several compounds can have identical retention times. Therefore, in this research, mass spectra data was essential to identify compounds with certainty. This figure also shows that ^-substituted aniline is more strongly absorbed on Carbowax 2CM than a ring-substituted aniline. o-Methyl- aniline has a longer retention time than N-methylaniline. Likewise, p-propy!aniline has a longer retention time than N-n-propylaniline. The reason for this is that- a primary nitrogen is more strongly absorbed than a secondary nitrogen. It should be noted that in subsequent identification of basic nitrogen compounds the amine forms of the compounds are identified. However, as was shown earlier, the basic nitrogen compounds leave tlie reactor in their hydrochloride salt forms. The amines are formed by treating the salts with a dilute potassium hydroxide solution. In this paper,, in order to avoid confusion between chromatogram "peaks" and mass spectrum "peaks" the former will be referred to as "traces." 2.

The aniline, quinoline, and 1,2,3,^-tetra- hydroquinoline traces were identified by comparing the retention times and mass spectra data of the traces with those of the pure compounds. Trace 4 is postulated to be N-allylaniline. A comparison of Figures 8 and 9 shows that trace H has a retention time similar to O-methylaniline and N-n-propylaniline. However, the mass spectrum for this compound as listed in Table 3 corresponds to neither 0methylaniline or N-n-propylaniline.

As can be seen from Table 3, This base peak is typical of - 27 substituted anilines (5). The parent peak of 133 with a large 132 peak is very similar to I ,2,3,H-tetrahydroquinoline. However, the retention time is wrong for this compound to be 1 ,2 ,3 ,4-tetrahydroquinoline. Therefore, a compound must be found with a molecular weight of 1.2.3.4- tetrahydroquinoline and a retention time of N-n-propylaniline. The obvious answer is a N-substituted aniline with an unsaturated three-carbon side chain. One possible candidate is N -allylaniline. This compound could easily be formed by opening the pyridine ring of 1.2.3.4- tetrahydroquinoline. 1,2,3,4-Tetrahydroquinoline N-Allylaniline Traces 5 and 6 were not large enough to be analyzed on the mass spectrometer but these might be o-methylaniline and o-ethylaniline based on retention times. The mass spectrum for trace T is listed in Table U along with data for p-propy!aniline. - 28 TABLE k: MASS SPECTRA DATA FOR TRACE 7 AHD p-PROPYLANILIRE Trace 7 m/e p-Propylaniline Relative Intesities m/e Comments Relative Intesities 55 3 55 4 77 27 77 11 79 14 79 9 106 100 106 100 107 12 107 10 118 9 118 5 135 18 135 18 lk6 15 Contamination I k rJ 12 in trace 7 Table U shows that trace 7 has more than one compound. However, it also shows that the major compound in trace 7 is very similar to p-propylaniline. A mass spectra comparison with N-n-propylaniline would be good, but the retention time, would rule it out. However, the retention time for p-propylaniline corresponds to trace 8 and not trace 7. But o-propylaniline could have a retention time like that of trace 7 and would have a similar mass spectrum. With the propyl group in the ortho position to the primary nitrogen there could be a shielding effect to reduce the absorption of the nitrogen. Thus o-propylaniline probably has a shorter retention time than p-propylaniline. Un­ fortunately, no o-propylaniline was available to test the hypothesis. Trace 9 could not be isolated sufficiently from trace 8 to get a separate mass spectrum. However, the mass spectrum of trace 8 has - 29 contamination peaks at lk2 and 1^3 corresponding to 15% and 22%, respectively, of the quinoline base peak, 129. Peaks 11+2 and 11+3 correspond to a methyIquinoline. When programming the column temperature on the 5-foot Carbowax column, traces were visible beyond I ,2 ,3 ,4-tetrahydroquinoline which were too broad on the large column to be seen. These traces were invariably composed of more than one compound. However, large mass peaks were observed at 156, 157, 170 and 171. The first two numbers correspond to a dimethy!quinoline or an ethylquinoline. The last two correspond to a trimethylquinoline, a methylethylquinoline,, or a propylquinoline. It is interesting to note that Ryffel (25) identified aniline, o-methylaniline,oo-ethylaniline, o-propylaniline, quinoline and 1, 2j3,l+-tetrahydroquinoline in the product oil of a destructive hydrogenation of quinoline over a cobalt-molybdate catalyst. 3.. Honbasic Compounds from Quinoline Runs A chromatogram from a 4.0 LHSV quinoline run is given in. Figure 10. A 1.6 LHSV run was used in all the other identifications. However, with the quinoline runs the nonbasic compounds were such a m i nor' fraction of the product that the 4.0 LHSV runs had to be used to obtain a chromatogram with visible traces. Traces I .and 2 of Figure 10 are p-xylene and an unknown compound. Trace 3 has not been identified. A mass spectrum of trace 3 has a base peak of l4l with other significant peaks at 115, 139, 142, l43 Chromatograph Variables: Temperature: 221 C Helium Flow: 50 ml/min Column: 10-ft Carhowax 20M I: 2: 3: U: 5: p-Xylene unknown unknown Dimer of p-Xylene a Methylindole 6: a CgH -indole I I U) I * FIGURE 10: Chromatogram of Nonhasic Compounds from 1+.0 LHSV Quinoline Runs - B l ­ and 1 U 5 .

The mass to charge ratio of these ions agrees with those of the mass spectrum for trace 4. No p-xylene dimer was available to compare for retention time or mass spectrum, but it is strongly suspected that the trace is the dimer. Trace 5 seems to be a methylindole. A mass spectrum of the trace had a base peak of 130 with 131 as another large peak. Dimethylindole or ethylindole appears to be the main constituent of trace 6 . However, as can be seen from Table 6 , a methylindole and a C^H^-indole are also present.

Honbasic Compounds from Indole Runs A typical chromatogram of the nonbasic compounds from a 1.6 LHSV indole run is given in Figure 13.

Hartung and coworkers (l4) identified the following nonbasic compounds from their work: • 3-isopropylindole, indole, 1,3-dimethyl2-ethylindole, 3-propylindole, 1-ethylindole, 2-tert-butylindole, other indole types, and carbazole types.

This fact combined with the fact that quinoline and 1 ,2 ,3 ,4-tetrahydroquinoline are present in the quinoline slate suggests that different mechanisms are involved in the hydrodenitrogenation of quinoline and indole and that basicity must play an important role in this difference. C. Reaction Mechanisms The nickelous chloride-gaseous hydrochloric acid catalyst behaves as dual functional catalyst. It contains sites for a hydrogenation function and for an acid function. The hydrogenation function is responsible for hydrogenation and dehydrogenation reactions. The acid function is responsible for cracking, isomerization,, and polymerization reactions (2 ). With this catalyst system, the following sites for hydrogenation and acidic activities are possible: -UoHYDROGENATION ACIDIC I) Ni HCl 2) H+ (NiCl3 )- H+ (NiCl3 )- 3) H+ (NiClgOH)- H+ (NiClgOH) These site combinations all involve nickel and hydrochloric acid. The reason for this is that McCandless (19, 20) showed that "a minimum amount of nickel and a minimum partial pressure of HCl are required for good denitrogenation activity." With the first of the above site combinations the hydrogenation / functions would take place at a nickel site on the catalyst surface. The acidic functions could take place either where hydrochloric acid is absorbed on the catalyst surface or possibly in the gas phase with gaseous hydrochloric acid. In either case, the nitrogen compound would have to migrate or diffuse from the nickel site to the hydrochloric acid site in order for the denitrogenation reaction to go to completion. With the last two active sites an entire denitrogenation reaction could conceivably take place at one location on the catalyst surface. The H+ (NiClgOH) liquid feed. site is possible since there might be some water in the Unfortunately, this research did not obtain the type of data necessary to identify the site combination actually present on the surface of this catalyst. Using•the product slates in Table 11 possible reaction mechanisms for the denitrogenation of quinoline and indole were postulated in Figures and 15, respectively. These mechanisms are very similar.

EiCl difference is that indole must first be reduced to a basic compound before it can react with the active site H+ '(NiCl ) . being a basic compound can react directly. However, quinoline One might speculate that it is this reduction step which causes indole to be more difficult to denitrogenate at 4.0 LHSV than quinoline. However, since indole was not identified in the 4.0 or 1.6 LHSV product oil from the indole runs, it is likely that indole was reduced quickly and irreversibly. Therefore, the reduction step would not be the limiting step in the reaction sequence. In Figure I4 the products of reactions 1,3,4 and 5 were identified in their amine forms. Also, ammonium chloride., one of the products of reaction 6 , was identified. I ,2-Dihydroquinoline was not identified but this compound has been found in the product of a mild reduction of quinoline (25). It is likely that the salt of I ,2-dihydroquinoline is formed in the reduction of quinoline but that it is immediately reduced to the salt of I ,2 ,3 ,4-tetrahydroquinoline. In Figure 15, the products of reactions 3, 4, 5 and the ammonium chloride from reaction 6 were identified. indoline was identified. However, neither indole nor . But this fact could be explained if reactions 1,2, and 3 were fast and irreversible. Then there would be little indole or indoline in the reaction product to be identified. The reactions in Figures I4 and 15 are reasonable. mechanisms could be possible. However, other For instance, it is possible that the o-methylaniline is an end product and not an i n t o Jiate in the indole — 46 — reaction sequence. This would mean that reaction 5 would not procede. Most of the aniline would then come from reaction 4. A sure way to test this mechanism would be to react the salt of o-methylaniline at the same reactor conditions as indole. Then a comparison of the reaction rates and product slates would indicate if step 5 is in the reaction sequence. As such runs and analyses were not made in this research, it is impossible to positively identify the reaction sequences for the denitrogenation of indole and quinoline, The presence of methylated quinolines and indoles in the quinoline product and high molecular weight anilines, carbazoles, and methylated indoles in the indole product is the result of destructive alkylation. Hydrocarbons from cracking reactions react with anilines, indoles and quinolines. Methylated indoles and quinolines are harder to denitrogenate than indole and quinoline (12). This means that complete denitrogenation of quinoline and indole would be difficult even at long reactor space time. Since alkylated anilines were identified in the product oil of indole and not quinoline runs this would suggest that the denitrogenation of indole is limited by one of the aniline or methylated aniline reactions. The salts of these compounds must have a long residence time in the reactor to allow alkylation to take place. Using similar logic, it would appear that quinoline must have a long . residence time in the reactor to allow quinoline to be .alkylated. This would suggest that either the initial reaction of quinoline to form the -U t salt with the active site or the reduction of this salt to the salt of I, 2-dihyroquinoline is the limiting reaction. The former case seems to he more likely. If in future work even more reduced conditions were selected and the product slates for these conditions were obtained for a number of space velocities then one could speculate with more assurance as ,to possible limiting reactions. V. SUMMABY and conclusions The following conclusions can he drawn from this work on the hydrodenitrogenation of indole and quinoline: 1. It is easier to remove nitrogen from the product oil of quinoline than indole at 4.0 LHSV, hut at lower space velocities little difference is observed. 2. Nitrogen leaves the reaction zone as ammonium chloride. 3. Hydrochloride intermediates appear to he present in the reaction sequence. 4. The amine forms of basic and nonbasic nitrogen compounds from indole and quinoline runs can he isolated. 5. Different reaction mechanisms with different limiting steps must he proposed for the denitrogenation of indole and quinoline. 6. Destructive alkylation reactions seem to occur. 7. Some of the p-xylene appears to dimerize. VI. RECOMMENDATIONS FOR FUTURE WORK Future work should "be aimed at testing the hypotheses proposed in this report concerning the type and location of the active sites, the reaction sequences, and the limiting reactions. The three programs outlined "below might be useful. 1. An intensive analysis of reacted catalyst pellets for nitrogen, nickel, and chloride content might shed some light on the type and location of the active sites. 2. Reaction of proposed intermediate compounds a t .the same reactor conditions as indole and quinoline and subsequent comparison of reaction rates and product slates would test hypotheses concerning reaction sequences. 3. Analysis of rate data and product slates from the denitrogenation of quinoline and indole at a number of space velocities and at less severe "reduced" conditions than those of this research would test hypotheses concerning limiting reactions in the reaction sequence.

The molecule is broken into ions. The ions have a particular ratio of mass to electronic charge, or m/e ratio. Most ions have a charge of one so that means that the m/e ratio is the mass of the ion. A ’’molecular ion" or "parent ion" is an ion which has not lost any mass and has lost only one electron: + - M + e ------M - + Se Molecular Ipn A table or plot of all m/e ratios found for a particular molecule and the respective relative intensities is called a "mass spectrum". In a plot of the m/e ratios the peak with the largest intensity" is called the "base peak". It is given a value of 100 and all other relative intensities are calculated from it. the base peak occurs at the molecular ion. Often A mass -spectrum for a molecule can be highly characteristic of that molecule (3)• This can be seen by looking at the API mass spectrums (6) and the experi­ mental mass spectrums which follow. Thus the mass spectrometer is a very powerful tool for identifying unknown compounds. - 56 - EXPERIMENTAL MASS SPECTRA DATA Para Xylene o-Methylaniline Relative Intensities m/e m/e 23 77 78 79 89 91 92 105 20 12 6 100 8 k 106 7 77 78 79 89 106 107 o-Ethylaniline Relative Intensities 21 55 77 78 79 93 io 6 107 135 21 77 78 79 91 7 21 10 100 6l 5 . lU 4 106 100 107 9 4 39 4 . 120 121 122 N-n-Propylanillne m/e Relative Intensities m/e Relative Intensities 10 20 5 13 4 100 10 18 p-Propylaniline m/e 55 77 79 106 107 Relative Intensities 4 11 9 100 10 118 5 135 18 - 57 - EXPERIMENTAL MASS SPECTRA DATA Indoline 1,2,3,^-Tetrahydroquinoline Relative ■ Relative m/e________ Intensities___________________ m/e_____________ Intensities 89 17 91 5 90 13 103 4 91 39 104 7 117 28 115 3 118 100 117 11 119 59 118 i4 129 3 130 11 132 100 133 OO 134 5 - 58 - MASS SPKCTHAL DATA A m orican Pvtroleum Institute R e s e a r c h Project 4 4 P i t t s b u r g h , Pa.
