A process is provided for reducing the sulfur content of a hydrocarbon stream, wherein a hydrocarbon stream containing sulfur constituents is contacted with a sorbent under temperature and pressure conditions of low severity. The sorbent includes a metal-exchanged zeolite selected from a group consisting of Y zeolites, ultra-stable Y zeolites, and mixtures thereof. A preferred sorbent is a fluid catalytic cracking (FCC) catalyst having a rare earth metal exchanged Y zeolite or ultra-stable Y zeolite. The sorbent adsorbs sulfur constituents contained in the hydrocarbon stream upon contact therewith to reduce the sulfur content of the hydrocarbon stream.

[ I claim:] [1.] A process for reducing the sulfur content of a hydrocarbon stream under temperature and pressure conditions of low severity comprising:providing a hydrocarbon stream containing a sulfur constituent;heating said hydrocarbon stream to a contacting temperature greater than ambient, but not greater than the reflux temperature of said hydrocarbon stream;contacting said heated hydrocarbon stream at said contacting temperature and at a contacting pressure not greater than about 698 kPa with a sorbent including a metal-exchanged zeolite having a silica to alumina ratio of at least about 1.5:1; andadsorbing said sulfur constituent contained in said hydrocarbon stream onto said sorbent to reduce the sulfur content of said hydrocarbon stream.
