Abstract
Abstract There is disclosed a process for cracking a metal-containing feed in the presence of a fluid cracking catalyst composition contacting said feed at catalytic cracking conditions with a catalyst composition comprising a zeolitic, crystalline aluminosilicate, sepiolite and matrix material, characterized in that the sepiolite is present in non-dispersed form.
