CATALYST FOR ENHANCED PROPYLENE IN FLUIDIZED CATALYTIC CRACKING

摘要

A fluid catalytic cracking catalyst for increased production of propylene and gasoline from heavy hydrocarbon feedstock, the catalyst comprising between 10 and 20% by weight of an ultra-stable Y-type zeolite, between 10 and 20% by weight of a phosphorous modified sub-micron ZSM-5, between 20 and 30% by weight of a pseudoboehmite alumina, and between 30 and 40% by weight kaolin.
