摘要： A novel hydrocarbon feedstream catalyst bed for the desulfurization of a gas or a liquid hydrocarbon feedstream and a process comprising passing a hydrocarbon feedstream over the catalyst bed is descrived. The bed comprises a least two catalysts having different sulfur compound affinities and / or specificities thereby improving the overall amount of sulfur compound removal. The process reduces the sulfur content in a gas hydrocarbon feedstream from up to about 300 ppm to less than about 500 ppb, and in a liquid hydrocarbon feedstream from up to about 3% to less than about 500 ppb.
