Effect of gas flow rate and discharge volume on CO₂ methanation with plasma catalysis

Abstract CO 2 methanation can be a key technology for realizing sustainable society. CH 4 is used as an energy carrier and raw material chemical products, thereby contributing to the reduction of emissions. Methanation with plasma catalysis lowers process temperature, which improve throughput stability. In this study, we investigated effect gas flow rate discharge volume on methanation, using low-pressure capacitively coupled reactor. Higher rates increase throughput, but selectivity decreases owing reduced transportation reactants catalyst surface. Increasing effective in improving rate. This study suggested that structure reactor significantly affects generation
