METHOD AND CATALYST FOR PREPARING OIL BODY Russian patent published in 1998 - IPC

FIELD: lubricating oil production. SUBSTANCE: oil body is prepared by bringing, under hydrogen atmosphere, hydrocarbon material in contact with catalyst containing hydrogenation component on amorphous alumino-silicate carrier with microporosity from 5 to 50 vol %, total pore volume 0.6-1.2 ml/g, and alumina content 5 to 75 wt %. Preferable raw material is gatch and synthetic paraffins and preferable active component of catalyst combines one or several metals from cobalt- iron-nickel group and one or several metals from chromium- molybdenum-tungsten group. Catalyst is especially effective when hydrocarbon material containing significant amounts of nitrogen and sulfur-containing compounds is used. EFFECT: increased catalyst efficiency. 12 cl, 5 tbl
