METHOD OF SYNTHETIC OIL PRODUCTION OUT OF GREENHOUSE GASES Russian patent published in 2015 - IPC C12P5/00 C12P39/00 C10L1/00 C12N1/12 

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 CO₂; synthetic oil produced by the above method, usage of synthetic oil as well as use of gas containing CO₂ are 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 CO₂; 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 CO₂.
