Tungsten tri oxide catalyst supported on mesoporous SBA-15 was prepared by thermal decomposition of ammonium para tungstate (APT). This method is very simple and facile in comparison to the previous similar research and high loading of WO3 particles in mesoporous SBA-15 can be obtained. After the sulfidization with dimethyl disulfide (DMDS), the product can be used as suitable catalyst in HDS process of naphtha and the other petroleum products. The as-prepared WO3/SBA-15 catalyst was characterized by XRD, SAXS patterns and SEM image. Besides, specific surface area and pore volume of the product was determined by nitrogen adsorption using a surface area analyzer and BET method.
