Abstract
A composition comprising a promoter and a metal oxide selected from the group consisting of a gallium oxide, an indium oxide, and combinations of any two or more thereof, wherein at least a portion of the promoter is present as a reduced valence promoter and methods of preparing such composition are disclosed. The thus-obtained composition is employed in a desulfurization zone to remove sulfur from a hydrocarbon stream.

A process for the removal of sulfur from a hydrocarbon stream comprising:
- (a) contacting said hydrocarbon stream with a composition comprising a promoter and a metal oxide selected from the group consisting of a gallium oxide and an indium oxide, wherein at least a portion of said promoter is present as a reduced valence promoter and in an amount which will effect the removal of sulfur from said hydrocarbon stream in a desulfurization zone under conditions such that there is formed a desulfurized hydrocarbon stream and a sulfurized composition;
- (b) separating said desulfurized hydrocarbon stream from said sulfurized composition thereby forming a separated desulfurized hydrocarbon stream and a separated sulfurized composition;
