Hydrogenation - an overview | ScienceDirect Topics

Hydrogenation involves the reaction between unsaturated liquid oil and hydrogen adsorbed on a metal catalyst. The oil is mixed with a suitable catalyst (usually nickel), heated (140–225°C), then exposed, while stirred, to hydrogen at pressures up to 60 psi (Nawar, 1996). First, a carbon-metal complex is formed at either end of the olefinic bond.
