Abstract

To provide a hydrocarbon synthesis method that can reduce carbon dioxide to yield hydrocarbons with 5 or more carbon atoms, and aromatic hydrocarbons, with high efficiency.SOLUTION: A hydrocarbon synthesis method reduces carbon dioxide with a carbon dioxide reduction catalyst, synthesizing hydrocarbons. The carbon dioxide reduction catalyst includes Na and Fe as catalyst metals, and a porous solid acid catalyst with its pores widened by alkali treatment. The alkali treatment is performed using a sodium hydroxide aqueous solution. Preferably, the sodium hydroxide aqueous solution has a concentration of 0.1-0.3 mol / L.SELECTED DRAWING: Figure 5
