The invention concerns a catalyst comprising nickel on an aluminum oxide support. The aluminum oxide support has, in the calcined state, a diffractogram obtained by X ray diffractometry comprising peaks which correspond to the following interplanar spacings and relative intensities: 

Selective hydrogenation catalyst, and process for its preparation

The invention concerns a catalyst comprising palladium on an oxide of aluminum support. In the calcined state, the oxide of aluminum support has a diffractogram obtained by X ray diffraction comprising peaks which correspond to the following interplanar spacings and relative intensities: 

Selective hydrogenation catalyst and process for its preparation

A method of preparing a composition of alcohol esters of linear monocarboxylic acids with 6 to 26 carbon atoms from a vegetable or animal oil, neutral or acid, virgin or recycled, with monoalcohols having 1 to 18 carbon atoms, in the presence of a catalyst combining at least a solid solution of ZnAlOtype, wherein x ranges between 0 and 1 (end points excluded), and free ZnO present between 7 and 30 mass %, allows to directly obtain, in one or more stages, an ester that can be used as fuel and a pure glycerin.
