Abstract Reducing CO2 to produce methane through microbial electrolytic cell (MEC) is one of the important methods of CO2 resource utilization. In view of the problem of low methanogenesis rate and weak CO2 conversion rate in the reduction process, the flow field environment of the cathode chamber is changed by changing the upper gas circulation rate and the lower liquid circulation rate of the cathode chamber to explore the impact on the reactor startup and operation and products. The results showed that under certain conditions, the CO2 consumption and methane production rate could be increased by changing the… More >
