METHOD OF PRODUCING OF RESIDUAL HIGH-VISCOSITY OILS Russian patent published in 1995 - IPC

Abstract RU 2034903 C1

FIELD: petroleum chemistry. SUBSTANCE: method involves hydrodeparaffinization and hydrotreatment of oily fractions in the single reactor with five-layer loading of cycling catalysts of hydrotreatment and hydrodeparaffinization (mass ratio is 1:2-1:3.5). Catalyst of hydrodeparaffinization: a composition consisting of, wt.-%: nickel oxide 4.5-5.5; chrome or tungsten oxide 9-13; talc 5-10; pentasil 40-50; tin 0.5-1.5; gamma-aluminium oxide - the rest. Process is performed at 375-425 C, under pressure 3-5 MPa, volume rate of raw feeding 1-2 vol. h/vol. h per hour, at hydrogen feeding 1000-1500 nm3/m3 raw. EFFECT: improved method of oils production. 1 tbl
