The development of special catalysts to convert SRC-II into a feedstock acceptable to a conventional petroleum refinery proceeded with the carrying out of several long-cycle runs. A catalyst comprising 4% CoO, 8% MoO/sub 3/, 1% NiO and 8% WO/sub 3/ on NALCO base 78-6008 was operated for 102 hours with burn-offs and resulfiding every three hours. The same catalyst was operated for 104 hours with regneration every eight hours. This catalyst was then operated for runs of 60, 100 and 300 hours with no burn-off. Harshaw's HT400 with 15% MoO/sub 3/ and 3% CoO was operated for a single cycle of 165 hours before cogeneration. These runs produced typically liquid yields of 90 to 100 vol. %, < 0.3 wt. % N/sub 2/ and < 0.3 wt. % S in the product, and a yield of 45% of 40 to 205/sup 0/C. gasoline possessing octane numbers of 75.1 MON, 88.3 RON, 81.7 (R+M)/2. A study of regeneration via burn-off and resulfiding showed a slight reduction in the size of the pores of the catalyst. Catalysts were prepared by impregnating 4% CoO, 2% MoO/sub 3/ and 2% WO/sub 3/ on seven different bases having pore diameters ranging from 90A to 420A. These catalysts as well as the unimpregnated bases were evaluated for denitrogenation ability with SRC-II. Preliminary results point to the 220A pore diameter as the best compromise between diffusion limitation and reduction in surface area.
