Additive for reducing gasoline sulfur in fluid catalytic cracking

摘要

The sulphur content of liquid cracking products, especially the cracked gasoline, of the catalytic cracking process is reduced by the use of a sulphur reduction additive comprising a non-molecular sieve support containing a high content of vanadium. Preferably, the support is alumina. The sulfur reduction additive 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.
