The objective of this project is to develop thermally stable, poison-tolerant catalysts that will be effective under moderate conditions in the hydrogenation or hydrodenitrogenation of nitrogen-containing heterocycles typical of coal liquids. The hydrogenation of model compounds, model compound mixtures and coal liquids will be carried out using the new class of catalysts, metallophthalocyanines. The catalysts (M(PC)) to be used are supported on silica, alumina, silica-alumina and titania; where M = V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ag, Mg, Pb, Sn, Si, Mo, Ru, Pt. The reduced forms, M/sub n//sup 1/(M(PC)) where M/sup 1/ = Na or Li and n = 1 to 5, are to be prepared and their catalytic activity evaluated. The initial screening of the catalysts will be done using quinoline as a substrate at 200 to 400/sup 0/C and pressure of 500 to 3000 psi H/sub 2/. The most effective catalysts will then be selected and used in hydrogenation of other model compounds like pyridine, pyrrole, indole, carbazole, isoquinoline, quinaldine, and acridine, in the hydrogenation of model compound mixtures and then coal liquids. The model compound mixture to be used consists of phenanthrene, dibenzothiophene, dibutylsulfide, quinoline, dibenzofuran and p-cresol. Coal liquids from the H-Coal process will be subjected to hydrotreating. Work completed in this quarter and discussed includes: (1) kinetics of hydrogenation of heterocyclic substrates; (2) activity of the 4, 4', 4'', 4''' tetramethylphthalocyanine cobalt (II) catalyst; and (3) catalyst degradation. 1 figure, 10 tables.
