Scherzer, J

This patent describes a process for the catalytic cracking of a hydrocarbon feedstock containing greater than about 0.25 weight percent total nitrogen, calculated as the element. It comprises contacting the feedstock with a cracking catalyst under cracking conditions in the substantial absence of added molecular hydrogen in a cracking zone to convert components of the feedstock into lower molecular weight constitutes. The cracking catalyst comprises greater than about 25 weight percent of a Y zeolite dispersed in a matrix comprising a clay and a synthetic silica-alumina component.
