Two runs of more than 100 hours of catalyst life were completed using SRC-I and SRC-II as the feeds. One run had catalyst regeneration every three hours, the other every eight hours. The catalyst, 4% CoO, 8% MoO/sub 3/, 1% NiO and 8% WO/sub 3/ on NALCO-78-6008C alumina base, reduced the nitrogen content to less than 0.3% and showed no signs of deterioration in activity. Regeneration after the three or eight hour periods was by burnoff with oxygen in nitrogen followed by re-sulfiding with H/sub 2/S in hydrogen. The liquid yield from SRC was 90% of which 30% was 50 to 204/sup 0/C. boiling range gasoline. It appears that a viable process to convert SRC into a feedstock acceptable to a petroleum refinery has been discovered. A study of the effect of carbon laydown on pore volume and subsequent deactivation of the catalyst was carried out in a pressurized batch reactor. Little reduction in pore volume was noted. Three commercial catalysts, Harshaw HT400, NALCO MO477 and NALCO MN502, were evaluated with SRC-II. These catalysts are capable of giving specification grade denitrogenation for up to five hours. The effect of added water to the feed stream lengthened the cycle time for the HT400 catalyst. About 25% of the liquid product is in gasoline boiling range.
