Production Of Liquid Hydrocarbon Mixture For Refining Petroleum
(AREA)
Abstract
FIELD: oil processing industry. SUBSTANCE: heated petroleum raw materials are mixed with oxidant at mass ratio 100:(5-20), the process is carried out at 150-225 C, sulfuric acid compound being used as mentioned above oxidant. Thus liberated gases and steams which mainly contain sulfuric anhydride and vapor are isolated and residue is heated to 300-340 C. Thus liberated gases and steams which mainly contain hydrocarbons, hydrogen sulfide and carbon dioxide are isolated to prepare desired bitumen. EFFECT: improves efficiency of method. 1 dwg, 6 tbl
