A catalytic cracking catalyst composition is disclosed that is suitable for reducing the sulfur content of catalytically cracking liquid products, in particularly gasoline products, produced during a catalytic cracking process. Preferably, the catalytic cracking process is a fluidized catalytic cracking (FCC) process. The composition comprises zeolite, zinc and at least one rare earth element having an ionic radius of less than 0.95 Å at a coordination number of 6. Preferably, 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.
