Abstract
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: Interplanar spacings d (10−10 m) Relative intensities ±5 × 10−3 d I/I0 (%) 4.54 3-10 2.70-2.75 5-25 2.41 35-45 2.28 15-30 2.10 0-10 1.987 30-50 1.958 30-50 1.642 0-5 1.519 10-20 1.394 100
