STUDY ON THE CONVERSION OF METHANE TO C_2 HYDROCARBONS THROUGH SYMMETRIC ELECTRICAL FIELD ENHANCING CATALYSIS

摘要

Low-power catalytic conversion of methane to C_2 hydrocarbons (ethane, ethylene and acetylene) through AC or DC plasma catalysis reactions in symmetric electrical field was studied under low temperature and atmospheric pressure. The function of catalyst was tested. The appropriate condition was: voltage 90 V～110 V (power 15 W～20 W DC); voltage 20 V～40 V(AC). The appropriate inlet flow of methane was 45 mL/min～80 ML/min under AC and DC field. The selectivity to C_2 hdyrocarbons was Above 95/100.
