Plasma Reforming and Coupling of Methane with Carbon Dioxide

摘要

Plasma reforming and coupling of methane with carbon dioxide using a point-to-point type of reactor have been invested. A feed mixture of CH_4 and CO_2 could be converted mainly to CO, H_2 and C_2H_2 at atmospheric pressure and without external heating except plasma heating. Under a condition of 200 mL/Min of Ch_4 and CO_2 (CH_4:CO_2 volume ratio, 50:50), a 2.5 mm discharge gap, and a pulse frequency of 10.3 kPPS, CH_4 and CO_2 conversion, CO and C_2H_2 selectivities, H_2/CO ratio, and (CH_4 +CO_2) conversion efficiency were 65.9/100 and 57.8/100, 85.9/100 and 11.3/100, 0.99, and 2.4 mmol/kJ, respectively.
