The desulfurization of sulfur compounds is a difficult problem of petroleum refining process. It was compared that there were many differences between the sulfur traditional method and active transition metal complexes of sulfur removal method. We have focused on a variety of transition metal Pd, Pt, Ru, Fe and organic contemporary desulfurization important instruction for the technology. sulfur compounds in the specific reaction pathways. The transition of technology of metal activity was Pd 〉Pt〉Ru 〉Fe, which has made petroleum r...
