ABSTRACT:
The catalytic activity of NiO based catalyst prepared from different salt precursors of acetate, nitrate
and sulphate salts were investigated towards CO2/H2 methanation reaction, in order to study the effect
of type of precursor on the reactivity of the catalyst prepared. Results obtained showed that the NiO
based catalyst prepared from nitrate precursor gave highest catalytic activity with 80.03% methanation
of CO2 at 500° C of the reaction temperature. Characterization techniques such as FTIR, XRD and SEM
were carried out to see the effect of various physical properties of the NiO based catalyst obtained from
different salts precursors used, which contributed in a good CO2/H2 methanation reactivity of the
catalyst.
