The present invention relates to a cracking catalyst composition comprising a physical mixture of 10-90 weight % of a cracking catalyst A and 90-10 weight % of a cracking catalyst B, whereby catalyst A is a zeolite-containing cracking catalyst, and catalyst B is a catalyst having a higher average pore volume in the pore diameter range of 20-200 .ANG. than catalyst A in the same pore diameter range and not containing M41S material. These compositions can suitably used for the fluid catalytic cracking of hydrocarbon feeds with high metal concentrations.

L'invention concerne une composition de catalyseur de craquage comprenant un mélange physique renfermant entre 10 et 90 % en poids d'un catalyseur de craquage A et entre 90 et 10 % en poids d'un catalyseur de craquage B, le catalyseur A étant un catalyseur de craquage renfermant une zéolite et le catalyseur B étant un catalyseur possédant un volume moyen de pores compris dans la plage de diamètre de pores entre 20 et 200 .ANG., ce volume moyen de pores étant supérieur à celui du catalyseur A dans la même plage de diamètre de pores et ne renfermant aucun matériau M41S. Ces compositions peuvent être utilisées de manière appropriée pour le craquage catalytique fluidique de charges d'hydrocarbones à concentrations métalliques élevées.
