ABSTRACT:
A process for the hydrogenation of hydrocarbon materials having olefinic unsaturation and/or olefinic-aromatic unsaturation, and particularly wherein hydrogenation is carried out at relatively low catalyst levels and mild reaction conditions whereby olefinic bonds are reduced and, when components of the reaction mixture contain aromatic unsaturation, to effect selective hydrogenation of olefinic bonds, without substantial, if any, hydrogenation of aromatic unsaturation; said process comprising contacting such hydrocarbon materials under hydrogenation reaction conditions of temperature and pressure in the presence of bis(1,5-cyclooctadiene) nickel as the hydrogenation catalyst.
