Gasoline sulfur content decrease catalytic converter for flow catalytic cracking process

摘要

A catalytic cracking catalyst composition is disclosed that is suitable for reducing the sulfur content of catalytically cracking liquid products, in particularly gasoline products and produced during a catalytic cracking process. Preferably and the catalytic cracking process is a fluidized catalytic cracking (FCC) process. The composition comprises zeolite and zinc and at least one rare earth element having an ionic radii of less than 0.95 Å at a coordination number of 6. Preferably and zinc and the rare earth element are present as cations that have been exchanged ON the zeolite. The zeolite is preferably a Y-type zeolite.
