The present invention relates to a method for producing synthetic natural gas using an adsorption part and a methanation reaction. More specifically, the present invention relates to a method for producing synthetic natural gas, which significantly reduces consumption of hydrogen gas and carbon dioxide production. To this end, carbon dioxide produced during methanation process for coal gas and biomass is removed by an adsorbent, and hydrogen is supplied to the methanation reaction by simultaneously carrying out a water gas conversion reaction. Carbon dioxide collected by the adsorbent is used again in the methanation reaction for carbon dioxide. According to the present invention, the method for producing synthetic natural gas using the adsorption part and the methanation reaction can reduce carbon dioxide emission and hydrogen consumption, thereby preventing global warming and being useful for producing synthetic natural gas in an economic way. |
