The sulfur content of liquid cracking products, especially the cracked gasoline, of the catalytic cracking process is reduced by the use of a sulfur reduction additive comprising a non-molecular sieve support containing a high content of vanadium. Preferably, the support is alumina. The sulfur reduction catalyst is used in the form of a separate particle additive in combination with the active catalytic cracking catalyst (normally a faujasite such as zeolite Y) to process hydrocarbon feedstocks in the fluid catalytic cracking (FCC) unit to produce low-sulfur gasoline and other liquid products.

1. A method of reducing the sulfur content of a liquid catalytically cracked petroleum fraction, which comprises catalytically cracking a petroleum feed fraction containing organosulfur compounds at elevated temperature in the presence of an equilibrium cracking catalyst and a product sulfur reduction additive to produce liquid cracking products of reduced sulfur content, wherein the product sulfur additive consists essentially of vanadium and a support selected from the group consisting of a refractory inorganic oxide and activated carbon.
