METHOD OF SYNTHETIC OIL PRODUCTION OUT OF GREENHOUSE GASES

摘要

FIELD: oil and gas industry.SUBSTANCE: group of inventions is related to method of synthetic oil production out of greenhouse gases. The invention suggests the method of synthetic oil production out of gas containing CO; synthetic oil produced by the above method, usage of synthetic oil as well as use of gas containing COare specified in the suggested method. The method includes the following stages: gas delivery to the reactor containing culture of at least one species of microalgae capable of photosynthesis; photosynthesis using CO; anaerobic fermentation of the received biomass; thermochemical decomposition of fermented biomass to receive synthetic oil mixed up with water and gas and separation of the produced synthetic oil. Upon photosynthesis stage from 5 up to 100% of the culture is removed from the reactor and divided into solid and liquid fraction. Solid fraction is subject to anaerobic fermentation stage. Carbonates and/or bicarbonates are separated from liquid fraction. Then liquid fraction less carbonates and bicarbonates is returned at least partially to the reactor.EFFECT: inventions ensure large capture of CO.29 cl, 5 dwg, 11 tbl, 3 ex
