METHOD TO PRODUCE STANDARD RAW MATERIAL OUT OF HIGHLY SULFUROUS OILS

摘要

FIELD: oil refinery. SUBSTANCE: method provides for contacting of demineralized and dewatered oil with alumonickel- and / or alumocobaltmolibdenum catalyst in hydrogen medium under high temperature and pressure. Method is distinguished for the fact, that as addition to demineralized and dewatered sulfurous oil catalyst they feed 1 - 20 volume % amount of one of organic alcohols mixture with hydrocarbon chain length C1 - C4 with water taken in amount at least 5 % of addition volume. Contacting is exercised with catalyst, that has volume of pores equal to 70 - 120A under temperature of 370 - 400 C and pressure of 35 - 70 atm with following processing according general scheme at refinery. EFFECT: increased productivity.
