Abstract:
1. A trim sulfur removal process for removing substantially all sulfur from hydrocarbon streams containing up to about 100 wppm sulfur, which process comprises: a) conducting a hydrocarbon stream containing up to about 100 wppm sulfur into a reaction zone wherein it is contacted with an effective amount of alkali metals including sodium on an inert support that is selected from the group consisting of alumina, silica, alumina-silica, and sodium carbonate, wherein said one or more alkali metals reacts with at least a portion of the sulfur in the hydrocarbon stream; b) conducting the treated hydrocarbon stream to a wash zone wherein it is contacted with an effective amount of water thereby resulting in an aqueous fraction containing water-soluble alkali metal components and a hydrocarbon fraction containing less than about 1 wppm sulfur; and c) separating said aqueous phase fraction from said hydrocarbon phase fraction.
