Improvement in the process for the preparation of a catalyst for cracking containing gel inorganico oxide, catalyst thus obtained.Process for cracking hydrocarbons which contains contaminants load post core units and process for application of said catalyst

摘要

Cracking catalysts prepared by the addition of asol of silica, alumina or mixtures thereof to an amorphousor zeolite cracking catalyst show improved resistance tometals poisoning and exhibit increased attrition resistanceand higher selectivity.
