The principal objective of this research is to uncover new reagents and catalysts for upgrading coal-derived fuels by removing undesirable organosulfur, organonitrogen and, if feasible, oxygen components. The studies in progress are: (1) evaluation of the desulfurization by reduced nuckel salts deposited on a solid support and used in percolation columns; (2) comparing the efficiencies of metal salts (Ni, Co, Cu and Mo), types of solid support (Al/sub 2/O/sub 3/, SiO/sub 2/, organic polymers) and operating temperatures; and (3) completing preliminary attempts to carry this procedure over to the denitrogenation of model compounds and SRC liquids. The following progress have been made: (1) reduced nickel supported on columns of alumina or poly-4-vinylpyridine and heated at 75/sup 0/C has been found to remove up to 80% of the sulfur from SRC liquids; (2) cobalt reagents have been found to be almost as effective, but copper and molybdenum have proved less efficient; (3) combinations of lithium and titanium salts have shown promise in cleaving C-N bonds in model compounds of the carbazole type; and (4) nickel supported on alumina not only removes much of the sulfur from SRC liquids, but has also been shown to reduce the nitrogen content from 0.91% to 0.01%.
