Processes for removing sulfur from a hydrocarbon stream utilizing silver-based sorbents
First Claim
1. A process for removing sulfur compounds from a hydrocarbon stream, the process comprising passing the hydrocarbon stream through an effective amount of a sorbent composition for a sufficient period of time to reduce sulfur compounds in the hydrocarbon stream to a level of no more than about 1 ppmw, the sorbent composition comprising porous titanium dioxide particles impregnated with a silver material, wherein the impregnated particles comprise about 97-99.9% titanium dioxide (w/w) and about 0.1-3% silver material (w/w).
