To develop an efficient cleaning technology of hydrocarbon resources, removal behavior of organic sulfur from a model fuel was investigated with the use of various metal compounds under a room temperature and atmospheric pressure. The model fuel was prepared by dissolving thiol, sulfide, disulfide and thiophene in n-dodecane. In the various metal compounds, lead oxide provided the highest selectivity for removal of thiol from the model fuel. XRD and FT-IR measurements clarified that sulfur from thiol was adsorbed on lead oxide surface as self-assemble monolayer of thiolate molecule. The adsorption rate of thiols on lead oxide strongly depends on initial concentration and forms ( aliphatic or aromatic) of sulfur.
