Zusammenfassung:	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 【課題】二酸化炭素を還元し炭素数が５以上の炭化水素、及び芳香族炭化水素を高効率で生成可能な炭化水素合成方法を提供すること。【解決手段】二酸化炭素を二酸化炭素還元触媒により還元し炭化水素を合成する炭化水素合成方法であって、二酸化炭素還元触媒は、触媒金属としてのＮａ及びＦｅと、アルカリ処理により細孔が拡大された多孔質固体酸触媒と、を含む、炭化水素合成方法。アルカリ処理は、水酸化ナトリウム水溶液により行われ、水酸化ナトリウム水溶液の濃度は０．１～０．３ｍｏｌ／Ｌであることが好ましい。【選択図】図５
