Abstract: Reactions between CH4 and CO2 under the action of continuous microwave discharge at atmospheric pressure were studied in a special homemade reactor. The main products were CO and H2, while acetylene and ethylene were also found in the products. Experimental results show that conversions of CH4 and CO2 could be higher than 90 % without the presence of any catalyst. Eects of CO2/CH4 molar ratio and total ow rate of the feed gas on the reaction were also investigated. Key words: CH4, CO2, microwave discharge, atmospheric pressure 1
