Abstract
The purpose of this project is to efficiently synthesis ethanol from syngas, which is
carbon monoxide and hydrogen gas. The overall goal that this project is trying to
achieve is to use ethanol as a renewable energy source. To capture as much ethanol
as possible, a Rhodium-based catalyst is being designed to convert as much of the
reactants as possible. This process begins with the calibration of the equipment,
followed by the synthesis of the catalysts. Finally, the reaction is run and the data is
analyzed.

Introduction
Corn is currently one of the largest sources of ethanol, especially in the United
States. Corn is also a significant source of food, so this will become a problem as
ethanol production and population increase. Therefore, it is important that we find
another source for ethanol so this problem can be avoided.
The reason that a Rh-based catalyst is being used is because it is known to
selectively produce things such as ethanol from syngas (Spivey, et al. 2007). The
specific Rhodium catalyst to be used in this project originated from the article “Synthesis
of ethanol from syngas over Rh/Ce1-xZrxO2 catalysts.” The reason that a
Rh/Ce0.8Zr0.2O2 catalyst is being used is because it produces the highest CO conversion
and ethanol selectivity in comparison to other Rh/Ce1-xZrxO2 catalysts (Liu, et al. 2011).
The main goal of this project is to engineer more efficient and effective catalysts
that will convert as much carbon monoxide as possible while maximizing the ethanol
selectivity. To achieve this goal, it is essential to become familiar with the project by
reading literature and working in the lab. Certain preparations must be made such as
calibration of the equipment and synthesis of the catalyst. Following these preparations
would be the actual running of the reaction and the collection and interpretation of the
data.
