This invention relates to a process for the preparation of a fluid catalytic cracking catalyst with improved attrition resistance. According to this preparation process, an aqueous slurry comprising a zeolite, clay, and poly aluminum chloride is spray-dried and subsequently calcined, the poly aluminum chloride having the formula [Al2(OH)yCl6-y]x, wherein x is at least 1 and y is greater than 2 and smaller than 4.

L'invention concerne un procédé de préparation d'un catalyseur de craquage catalytique fluide présentant une résistance à l'attrition améliorée. Selon ce procédé de préparation, une suspension aqueuse comprenant une zéolite, de l'argile, et du chlorure de poly aluminium est séchée par pulvérisation puis calcinée, le chlorure de poly aluminium ayant la formule [Al2(OH)yCl6-y]x, dans laquelle x est au moins 1 et y est supérieur à 2 et inférieur à 4.
