The present disclosure provides low trans-fatty acid fat compositions, methods of hydrogenating unsaturated feedstocks (e.g., oils), and hydrogenation catalyst compositions. One exemplary method involves producing a catalyst composition by heating a nickel-based catalyst to a first temperature of at least about 85° C in the presence of hydrogen and a fat component. An unsaturated feedstock may be contacted with the catalyst composition and hydrogenated by sustaining a hydrogenation reaction at a second temperature of no greater than about 700 C. Some specific implementations of the invention permit the production of partially hydrogenated seed oils with low trans-fatty acid contents.

This disclosure describes select low trans-fatty acid fats and fat compositions and methods of making such fats and fat compositions. These fats and fat compositions achieve properties commonly associated with typical partially hydrogenated fats, but avoid the high trans-fatty acid contents typically associated with such fats.

The present invention is directed to methods for making metal oxide compositions, specifically, metal oxide compositions having high surface area, high metal/metal oxide content, and/or thermal stability with inexpensive and easy to handle materials. In one embodiment, the present invention is directed to methods of making metal and/or metal oxide compositions, such as supported or unsupported catalysts. The method includes combining a metal precursor with an organic acid to form a mixture and calcining the mixture for a period of time sufficient to form a metal oxide material.
