| Regulations that will require reduced amounts of heteroatom impurities in transportation fuels in the near future have led to efforts to develop more active hydrotreating catalysts. Research in a number of laboratories has recently shown oxide-supported metal phosphides to be highly active hydrodesulfurization (HDS) catalysts. The goal of this research is to systematically investigate the effects of the oxide support on the HDS properties of two transition metal phosphides (Ni2P, MoP) which have been found to have high activities on silica. The synthesis of these materials on several oxide supports including zeolites (ZSM-5 and NaY), amorphous silica-aluminas of varying composition, and mesoporous molecular sieves will be described. The results of catalyst characterization studies as well as of thiophene HDS activity measurements will be discussed. The phosphide catalysts will be compared with sulfide-based catalysts supported on the same oxide materials. |
