METHOD OF LIQUID HYDROCARBON PRODUCTION USING FISCHER-TROPSCH METHOD Russian patent published in 2008 - IPC C10G2/00 C07C1/04 

FIELD: chemistry.

SUBSTANCE: invention refers to advanced method of hydrocarbon gas conversion to liquid hydrocarbons using Fischer-Tropsch method. And specified method implies that liquid hydrocarbons and residual gas are produced, and the latter contains at least hydrogen, carbon monoxide, carbon dioxide and hydrocarbons of carbon number not more than 6. Residual gas is PSA (Pressure Swing Adsorption) separated, using PSA separator. Additionally at least one gas flow is performed containing mainly hydrogen and resulting in: at least one gas flow containing methane, for which hydrogen and carbon monoxide extraction level is equal to at least 60%, at least one gas flow containing methane, for which carbon dioxide extraction level is equal to at least 40%, and at least one additional gas flow containing mainly hydrocarbons with carbon number at least 2. Method allows for considerable reduction of CO₂ atmospheric emission.

EFFECT: reduction of CO₂ atmospheric emission.
