Production Of Liquid Hydrocarbon Mixture For Refining Petroleum
(AREA)
Abstract
FIELD: petroleum chemistry. SUBSTANCE: petroleum oil is obtained by deasphalting of residual oil or tar by nonpolar hydrocarbon-type solvent C-C(preferably 50 to 70 mass percent) with formation of a solution of deasphaltizate in solvent with subsequent catalytic hydrocracking of it, separation of solvent and recirculation of solvent for deasphalting. The process is conducted with fractionation of the product of catalytic hydrocracking and dewaxing of obtained oil distillate products. Yield of petroleum oils is up to 58.5 mas percent. EFFECT: enhanced yield of end product. 2 cl, 3 tbl
