<p>A catalyst contains 1 to 99 wt.% of an inorganic binder and 99 to 1 wt.% of a zeolite consisting of a faujasite having an Si:Al synthesis ratio at least equal to 3 and derived by dealumination faujasite. The zeolite has an Si:Al ratio between 3 and 30 and the compensation cations of this zeolite consist partly or wholly of cations of one or more elements chosen from H, B, Al, Ga, In, rare earth metals and transition metals. The catalyst can also contain up to 15 %, referred to the total weight of the binder and zeolite, of a catalytically active metal of the noble, non-noble transition or other type which is not already present in the compensation cations of the zeolite. The catalyst can be used in acid catalysis reactions carried out on hydrocarbon feedstock, in particular in fluidized bed catalytic cracking.</p> |
