Abstract
A nitrogen-containing nickel catalyst adapted for catalyzing partial and selective hydrogenation of natural oils is disclosed, which comprises nickel and such an amount of a nitrogen-containing basic compound which is equivalent to from about 5 to about 40 atoms of nitrogen per 100 atoms of nickel. The catalyst is effective in catalyzing the partial hydrogenation of natural oils in such a manner that poly-unsaturated compounds are selectively hydrogenated and the formation of saturated compounds, transisomers, and conjugated dienes is limited and liquid hydrogenation products can be obtained. The catalyst is prepared by treating a nickel catalyst with the nitrogen-containing compound at elevated temperatures optionally under hydrogen.
Claims6
A process for partially and selectively hydrogenating a natural oil which comprises the step of treating said natural oil in the presence of a nitrogen-containing nickel catalyst comprising activated nickel and having incorporated therein by absorption an amount of a nitrogencontaining basic compound equivalent to from about 5 to about 40 atoms of nitrogen per 100 atoms of nickel with hydrogen at a hydrogen pressure and a reaction temperature sufficient to obtain a substantially liquid hydrogenation product rich in monoenic compounds and low in saturated compounds, trans-isomers and conjugated dienes.
