Catalytic methods for improved coal liquefaction and hydrotreating: Quarterly report No. 6 for the period December 23, 1986 through March 22, 1987
During this quarter we synthesized two new ruthenium catalysts. The first catalyst, Ru/sub 3/(CO)/sub 12/ supported on alumina, Ru(OM), was prepared to compare the reactivity of supported ruthenium carbonyl with that of bulk ruthenium, and with the RuMo(OM) catalyst prepared last quarter. The second catalyst was a RuCoMo catalyst prepared from the promotion of sulfided Harshaw CoMo with ruthenium trichloride, rather than with ruthenium carbonyl, which was used in previous preparations. We found that the ruthenium supported on alumina, Ru(OM), had the same activity and selectivity as bulk ruthenium, and was totally poisoned by hydrogen sulfide, as was the bulk metal. We also found that the RuCoMo prepared by ruthenium trichloride promotion had a similar activity and selectivity as the RuCoMo catalyst prepared by ruthenium carbonyl impregnation. Comparisons of the CoMo and RuCoMo catalysts were made on the HDN of decahydroquinoline (DHQ). We found in both cases the HDN product was almost exclusively propylcyclohexane, showing that the formation of propylbenzene during the HDN of quinoline must come from propylaniline or benzotetrahydroquinoline. We also compared the surface areas and pore sizes of the Harshaw CoMo and promoted RuCoMo catalysts and found them very similar. This quarter we presented a summary of our work on our use of organometallic precursors and promoted RuCoMo catalysts at the Denver ACS meeting. 4 refs.
