Catalytic cracking catalysts and additives which comprise a rare earth binder component are especially useful for catalytic cracking processes involving hydrocarbon feedstocks containing high metals content. The catalysts and additives may be used in conjunction with zeolite-containing cracking catalysts to enhance catalytic activity/selectivity especially for vanadium- containing hydrocarbon feedstocks. The rare earth binder component is preferably derived from a rare earth acid sol.

Des additifs et des catalyseurs de craquage catalytique comprenant un liant des terres rares conviennent particulièrement aux procédés de craquage catalytique pour charges de départ hydrocarburées à teneur métallique élevée. On peut utiliser ces catalyseurs et additifs conjointement avec des catalyseurs de craquage au zéolite afin d'accroître la sélectivité/l'activité catalytique, en particulier pour des charges de départ hydrocarburées contenant du vanadium. Ce liant des terres rares est de préférence dérivé d'un sol acide des terres rares.
