Catalytic hydrogenation of coal-derived liquids. Interim report, June 1977--August 1977. [Cobalt and nickel molybdates

Abstract

For COED pyrolysis oil, the screening of available commercial catalysts was completed. Cobalt molybdates are the best for desulfurization, nickel molybdates the best for denitrogenation. For PAMCO Solvent Refined Coal (SRC) Vacuum Flash Feed, the best desulfurization to date has been obtained with cobalt molybdate catalysts. Analyses including desulfurization, denitrogenation and ASTM distillations for nine previously reported runs and eleven new runs are reported. For SYNTHOIL, four more runs were completed and correlated with the previously reported forty-five runs. The evaluation of two more commercial catalysts and two MSU-fabricated catalysts was completed.
