This report describes the results obtained by using low concentrations of the following minerals and transition metals in a continuous coal process development unit (CPDU): zinc sulfide, reduced Robena pyrite, molybdenite (molybdenum disulfide), cobalt, nickel and molybdenum salts impregnated on coal. Substantial improvement in coal conversion was observed with low concentrations of zinc sulfide, reduced Robena pyrite and molybdenite. Oil production increased by over a factor of two. Impregnation with cobalt, nickel and molybdenum substantially increased the oil production and gave lower hydrogen consumption. Preliminary data indicated that the catalytic activity of molybdenum was independent of the mode of catalyst addition.
