For COED pyrolysis oil the evaluation of commercially available hydrotreating catalysts showed that the best denitrogenation catalysts are Cyanamid HDS9A and Harshaw HT 500 but only about 30% nitrogen reduction is obtained. The best hydrodesulfurization catalysts are Harshaw HT 400, Shell 344 and Cyanamid HDS20A with about 90% of the sulfur removed. The program is now devoted to synthesizing new catalysts for this specific feed stock. Five Ketjen and one Norton supports impregnated with molybdenum, cobalt and nickel are being evaluated. For PAMCO Solvent Refined Coal (SRC) Vacuum Flash Feed, the best commercially available denitrogenation catalyst is Harshaw Co--Mo--0401--T--/sup 1///sub 8/''. The best desulfurization catalyst is Shell 324-E-/sup 1///sub 16/''. Improved desulfurization was obtained with a catalyst fabricated here containing 0.2% NiO, 1.1% CoO, 15.5% MoO/sub 3/ on alumina and improved denitrogenation was accomplished with a catalyst comprising 0.26% NiO, 1.15% CoO, 13.1% MoO/sub 3/ on a Ketjen support. For SYNTHOIL the best commercially available catalyst for desulfurization is Harshaw HT 500, for denitrogenation, Shell 324.
