Abstract
To provide a method for efficiently converting CO2 having low sulfur compound concentration into hydrocarbons.SOLUTION: A method for producing hydrocarbon includes: a gas separation step of separating CO2 gas having low sulfur compound concentration from by-product gas containing CO2 and sulfur; and a CO2 conversion step of producing hydrocarbon by converting CO2 contained in the CO2 gas from the gas separation step by means of a catalyst. The gas separation step includes an absorption tower extraction step of bringing a methanol absorption liquid fed into the inside of the absorption tower into contact with by-product gas introduced into the absorption tower to absorb components of the by-product gas, extracting a CO2-rich and S-rich absorption liquid at a lower stage of the absorption tower, and extracting a CO2-rich absorption liquid at a middle stage of the absorption tower.SELECTED DRAWING: Figure 1
