It is the objective of this research to convert coal to clean distillate fuels. This program will be limited to research on the product of PAMCO's solvent refined coal (SRC). The SRC will be heated and pumped, with and without solvent, into a catalytic reactor in the presence of hydrogen and other reducing gases. Variables to be investigated will include temperature, pressure, space velocity, hydrogen-to-oil ratio and chemical nature of the solvent. The catalysts to be studied will include nickel molybdate and sulfide, nickel tungstate and other combinations on carriers such as mordanites and other molecular sieved types. The work on the development of catalysts capable of converting solvent refined coal, SRC-II, into a feedstock suitable for a conventional petroleum refinery was continued. This requires a process which reduces the nitrogen content from the 1.17% in SRC-II to at least as low as 0.3%. Four catalysts were fabricated and evaluated. A cobalt, molybdenum, nickel, tungsten metal loading was made on a molecular sieve base possessing 88.9A average pore diameter. It produced specification product before and after burnoff with air. Three cobalt molybdate catalysts of different metal loadings were fabricated on three different pore diameter bases, 88.9A, 156.5A and 186.2A. Specification grade denitrogenation and regeneration was accomplished although all the results are not yet in. A blank run with no metal loading had no merit as a denitrogenation catalyst.
