Berg, L; Kim, N K

A catalyst for denitrogenating and desulfurizing liquified or solvent refined coals and lignite which includes catalytic metal oxides and/or sulfides impregnated within a porous base of principally alumina with large surface area and pore volume and pores of sufficient diameter throughout to accomodate the liquified coal or lignite molecules. The base material includes surface area of 150-500 m/sup 2//gm, pore volume of 0.4-1.0 ml/gm, average pore diameter of 40-250 A with no part of the pore less than 40 A. The catalytic metals impregnated into these base materials include 4-20% MoO/sub 3/, 1-8% CoO, 2-16% WO/sub 3/ and/or 1-4% NiO.
