摘要:
The invention concerns a catalyst comprising nickel on an aluminium oxide support. The aluminium 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 spacingsRelative 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 2.7315-35 2.60 5-10 2.4335-40 2.2930-40 1.9960-95 1.9525-50 1.79 1-10 1.53 5-10 1.51 5-10 1.4140-60 1.39100 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
摘要:
The invention relates to a catalyst that contains at least one matrix, a partially amorphous Y zeolite, optionally at least one metal that is selected from the group that is formed by the metals of group VIB and group VIII of the periodic table, optionally at least one element that is selected from the group that is formed by phosphorus, boron and silicon, optionally at least one element of group VIIA, and optionally at least one element of group VIIB. The partially amorphous Y zeolite has a peak rate that is less than 0.4, and a crystalline fraction that is expressed relative to a reference zeolite in sodium form and that is less than 60%. The invention also relates to the use of this catalyst in hydroconversion, in particular hydrocracking and hydrorefining of hydrocarbon feedstocks.
