Selective hydrogenation catalyst, and process for its preparation

摘要

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: Interplanar spacings Relative intensities d (10-10 m ) I/I0 (%) 5.03 to 5.22 1-5 4.56 to 4.60 1-10 4.06 to 4.10 1-5 2.80 to 2.85 5-20 2.73 15-35 2.60 5-10 2.43 35-40 2.29 30-40 1.99 60-95 1.95 25-50 1.79 1-10 1.53 5-10 1.51 5-10 1.41 40-60 1.39 100 1.23 to 1.26 1-5 1.14 5-10 1.11 1-5 1.04 1-5 1.00 5-10 0.97 1-5.
