Catalytic methods for improved coal liquefaction and hydrotreating: Quarterly report No. 5 for the period September 23, 1986 through December 22, 1986

The goal of this project is to optimize the reaction conditions for coal liquefaction and upgrading coal liquids. Accomplishments for this quarter are presented for the following tasks: (1) synthesis of catalysts; (2) hydrodenitrogenation (HDN) activity of catalysts with model system; and (3) catalytic reactions and additives on coal and coal liquids. For task 1, variations of bi/sup -/, tri/sup -/, and tetrametallic catalysts (RuMo, FeCoMo, RuCoMo, RuFeCoMo), were prepared to compare with catalysts prepared during the last quarter. For task 2, we found that the ruthenium-doped organometallic catalyst, RuMo (OM), was considerably more active and more selective than the RuNiMo (OM) catalyst. The RuFeCoMo catalysts, formed from doping ruthenium on FeCoMo, was also a very active catalyst, and far more active than the corresponding FeRuCoMo catalyst, formed from doping iron on RuCoMo. We treated an SRC-II coal liquid with the RuCoMo catalyst, recovered it, and tested it for HDN activity on our model systems. This aged catalyst was highly selective toward aromatic products and although it had reduced HDN activity compared to a fresh sample, it was still more active than the nonpromoted CoMo catalyst. For task 3, an SRC-II coal liquid was treated with a promoted Harshaw CoMo catalyst, RuCoMo. Although the activity of this catalyst was similar to that of the CoMo catalyst, the hydrogen consumption was less with ruthenium catalyst. 7 refs., 3 tabs.
