ABSTRACT

Production of CH4 has been established using a low-pressure square-pulse cross-field CO2/H2 discharge with magnetic field. The conversion rate from CO2 to CH4 was investigated by changing the discharge parameters such as applied power and discharge distance, together with magnetic field strength. Carbon dioxide was reduced by hydrogen. The discharge took place across the magnetic field inside a glass tube. Decomposition of CO2 and CH4 selectivity are found to be dependent on power density. Energy efficiency for methane production is increased in a narrow discharge. Preferable improvements of CO2 decomposition, CH4 selectivity, and energy efficiency were established.
