PROCESS FOR THE PREPARATION OF AN FCC CATALYST

摘要

This invention relates to a process for the preparation of a fluid cataly tic 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 aluminu m 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.
