Abstract

See full text

A particulate catalytic cracking catalyst which comprises a zeolite having catalytic cracking ability under catalytic cracking conditions, added silica, precipitated alumina and, optionally clay. The catalytic cracking catalyst has a high matrix surface area and is useful in a catalytic cracking process, in particularly, a fluid catalytic cracking process, to improve bottoms conversion at a constant coke formation.
