Chemistry and morphology of coal liquefaction. Quarterly report, January 1, 1984-March 31, 1984
In task 1, selective synthesis of gasoline-range components from synthesis gas, rate expressions were developed for four different iron catalysts (promoted and unpromoted). Data for all four catalysts can be correlated by a semi-empirical expression. In task 2 catalyzed low temperature reactions of carbon and water, the catalytic activity for the production of hydrocarbons from graphite and water over KOH plus a co-catalyst was investigated for several first row transition metals. NiO showed the greatest activity. Several samples of /sup 13/CO, /sup 13/CO/sub 2/ and H/sub 2/O adsorbed on graphite and on catalyst-graphite systems after reaction with steam were prepared for NMR investigation. In task 3 chemistry of coal solubilization and liquefaction, rate studies of quinoline reduction to tetrahydroquinoline in the presence of the homogeneous catalysts (phi/sub 3/P)/sub 3/RhCl have provided definitive evidence that benzothiophene, indole, pyrrole, carbazole, thiophene, p-cresol and dibenzothiophene enhance the initial rate of hydrogenation of quinoline by a factor greater than 1.5. P-cresol was found to enhance the initial rate of hydrogenation of quinoline (1.6 to 2 fold) in a model coal liquid with polymer-supported (2% cross-linked) (phi/sub 3/P)/sub 3/ RhCl. 2 references, 6 figures.
