Abstract
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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
90 words
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.
Claim 2
Dependent Claim
90 words
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.
Claim 3
Dependent Claim
34 words
The process as defined in claim 1, wherein the nitrogen-containing catalyst is present in an amount corresponding to from about 0.01 to about 0.75% of nickel, based on the weight of the natural oil.
Claim 4
Dependent Claim
19 words
The process as defined in claim 1, wherein the reaction temperature is between about 100° and about 175° C.
Claim 5
Dependent Claim
19 words
The process as defined in claim 1, wherein the hydrogen pressure is between about 0.5 and about 10 kg/cm2.
Claim 6
Dependent Claim
40 words
The process as defined in claim 1, wherein the treatment with hydrogen is carried out until the iodine value of the hydrogenation product is from about 10 to about 40 units lower than the iodine value of the starting oil.
Claim 7
Dependent Claim
15 words
A hydrogenated natural oil which is obtained by the process as defined in claim 1.
