Catalytic hydrogenation of coal-derived liquids. Interim report for the period January 1978 through March, 1978
With the COED pyrolysis oil, eight cobalt-nickel-molybdenum on alumina-silica supported catalysts were fabricated and evaluated for their desulfurization, denitrogenation and hydrocracking ability. Partial data obtained to date is too scattered to draw firm conclusions. Eleven continuous runs were made with PAMCO Solvent Refined Coal Vacuum Flash Feed at 450/sup 0/C, 1000 psig, 10,000 ft/sup 3/ of H/sub 2/ per bbl. of oil and liquid hourly space velocities of 1 to 2. The best desulfurization was obtained with a NiO, CoO, MoO/sub 3/ on alumina, the best denitrogenation with a similar impregnation on alumina-silica. With SYNTHOIL, two continuous flow runs made at 450/sup 0/C, 800 psig, 10,000 ft/sup 3/ of H/sub 2/ per bbl. of oil and liquid hourly space velocities of 1 to 2 indicate that he best hydrodesulfurization catalyst, about 64%, is Cyanamid's HDS-9A -E /sup 1///sub 16/'' nickel molybdate on alumina and the best hydrodenitrogenation catalyst, about 43%, is Shell's 324-E-/sup 1///sub 16/'' nickel molybdate on alumina. Higher temperature (500 to 550/sup 0/C) hydrocracking gives a greater yield of lower boiling liquids but is accompanied by excessive carbon laydown on the catalyst.
