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 from the 1.17% in SRC-II to at least as low as 0.3%. Three catalysts containing molybdenum, cobalt, nickel and/or tungsten on bases of specific surface area, pore volume and pore diameter, were fabricated and partially evaluated. Two of them produced product equaling or exceeding the nitrogen specification. Regeneration via an air burn-off of the deposited carbon was accomplished on all three of the catalysts and a subsequent run with each indicated that activity had been restored. It appears that we are developing a combination hydrotreating-hydrocracking catalyst that has a life of five to eight hours and then requires a carbon burn-off and re-sulfiding in order to be re-used.
