Abstract
NiC composite catalyst was synthesized by carbon deposition over skeletal Raney nickel by exploiting
methane decomposition reaction and applied in the hydrogenation of isophorone. Nickel content in
the composite catalyst was ascertained by atomic emission spectroscopy. Influence of operating variables
(agitation, solvent, temperature, H2 pressure and isophorone concentration) on the hydrogenation of
isophorone over the NiC composite catalyst was investigated. Ethyl acetate was observed to be an
excellent solvent for the reaction in terms of both isophorone conversion as well as
3,3,5-trimethylcyclohexanone selectivity. The catalytic reaction was observed to be 0.06 order with
respect to isophorone and 0.82 order with respect to H2.
