Abstract

L'invention concerne un procédé de craquage catalytique. Pour éliminer au moins partiellement les oxydes de soufre de l'effluent gazeux du régénérateur d'une unité de craquage catalytique à lit fluidisé alimentée avec une charge contenant des composés soufrés et les convertir en hydrogène sulfuré dans la zone de craquage, on les met en contact avec au moins un composé d'une terre rare, de préférence du cérium ou un mélange de terres rares riches en cérium, supporté par des particules discrètes d'alumine. Les particules d'alumine peuvent faire partie d'un catalyseur composite de craquage ou être distinctes des particules de catalyseur et mélangées à celles-ci.The invention relates to a catalytic cracking process. In order to at least partially remove the sulfur oxides from the gaseous effluent from the regenerator of a fluidized bed catalytic cracking unit supplied with a feedstock containing sulfur compounds and convert them to hydrogen sulfide in the cracking zone, they are put into operation. contact with at least one compound of a rare earth, preferably cerium or a mixture of rare earths rich in cerium, supported by discrete particles of alumina. The alumina particles may be part of a composite cracking catalyst or be separate from and mixed with the catalyst particles.
