1. A process for hydrogenating a polyunsaturated compound comprising:
- placing the polyunsaturated compound in contact with a hydrogenation catalyst comprising a hydrogen peroxide-treated copper carbonate/copper hydroxide material, thus producing a mixture; and
heating the mixture at a temperature between 50°
C. and 250°
C. under a hydrogen atmosphere;
thus hydrogenating the polyunsaturated compound.

Abstract
Copper compositions that are useful as hydrogenation catalysts are disclosed. In particular, the copper compounds are catalysts for the selective hydrogenation of oils that contain unsaturated fatty acyl components such as unsaturated vegetable oils. Methods of preparing the copper compositions are also disclosed. Methods of hydrogenating unsaturated compositions that contain at least two sites of unsaturation using the hydrogenation catalysts, along with products obtained from the hydrogenation reactions described herein are also disclosed.

14. A process for hydrogenating a composition containing at least two sites of unsaturation comprising:
-
placing the composition containing at least two sites of unsaturation in contact with a hydrogenation catalyst consisting essentially of a hydrogen peroxide-treated malachite material, wherein the treated malachite material has an improved ability to catalyze hydrogenation as compared to a non-treated malachite material, thus producing a mixture; and heating the mixture at a temperature between 50°
C. and 250°
C. under a hydrogen atmosphere;thus hydrogenating the composition.
