초록

Development of carbon-neutral fuel production technologies to solve climate change issues is progressing worldwide. Among them, methane can be produced through the synthesis of hydrogen produced by renewable energy and carbon dioxide captured through a CO2 methanation reaction, and the fuel produced in this way is called synthetic methane or e-methane. The CO2 methanation reaction can be conducted via biological or thermochemical methods. In this study, a 30 Nm3/h thermochemical CO2 methanation process consisting of an isothermal reactor and an adiabatic reactor was used. The CO2 conversion rate and methane concentration according to the temperature measurement results at the center and outside of the adiabatic reactor were analyzed. The gas flow into the adiabatic reactor was found to reach equilibrium after about 1.10 seconds or more by evaluating the residence time. Furthermore, experimental and analysis results were compared to evaluate performance of the reactor.
