FIELD: petroleum processing. SUBSTANCE: method involves contact of desalted and dehydrated crude oil with aluminonickel- and aluminocobalt-molybdenum catalysts charged in mixture with elementary sulfur under hydrogen atmosphere at elevated temperature and pressure and is distinguished with that above said contact is performed consecutively in two steps: first with aluminocobalt-molybdenum catalyst at 350-400 C and pressure 30-40 gage atm and then with aluminonickel-molybdenum catalyst at 400-450 C and 40-70 gage atm, provided that first-step product is supplemented with 1-10 vol.% of organic oxygen-containing compound. EFFECT: enhanced efficiency of petroleum processing. |
