The goal of this project is to optimize the reaction conditions for liquefying coal and upgrading coal liquids. This quarter we concentrated on Tasks 1 and 2. In Task 1, Synthesis of Catalysts, we doped one of our organometallic-based NiMo catalysts with ruthenium to compare with the ruthenium-doped Harshaw catalyst (RuCoMo). We also added iron to the Harshaw-based RuCoMo catalyst to form an FeRuCoMo catalyst. In Task 2, HDN Activity of Catalysts with Model Systems, we furthered our efforts to study the mechanism and reactivity of the CoMo and RuCoMo catalysts. We studied cyclohexene under HDN conditions, in the presence of quinoline, and found that it is rapidly hydrogenated to cyclohexane but is not dehydrogenated to give benzene. We also tested and compared the Harshaw NiMo catalyst with the RuNiMo catalyst synthesized last quarter. We found the RuNiMo catalyst more active and more selective for HDN of quinoline to propylbenzene than the commercial NiMo catalyst. An organometallic-based RuNiMo catalyst was also tested and found to be very active and selective, but not as selective as the promoted commercial catalysts. The FeRuCoMo catalyst was tested and found to have activity similar to that of the CoMo catalyst; however, it has a higher selectivity to aromatic products. 4 refs., 8 figs., 3 tabs.
