Methane Conversion to C2Hydrocarbons by Abnormal Glow Discharge at Atmospheric Pressure

摘要: Methane conversion to C2 hydrocarbons has been investigated with the addition of hydrogen in a plasma reactor abnormal glow discharge at atmospheric pressure. The aim this experiment is minimize coke formation and improve stability. typical conditions are 300 ml total feed flux 400 W power. experimental results show that methane from 91.6% 35.2% mol, acetylene selectivity 90.2% 57.6%, ethylene approximately 7.8% 3.6%, where increases gradually along increase CH4/H2 2: 8 9: 1. A stable for considerable running time can be obtained only lower ratio = or 3: 7. These phenomena indicate deposition during obviously reduced by adding large amount an discharge. qualitative interpretation presented, namely, abundant hydrogen, possibility molecules activated radicals increased help react carbon form hydrocarbon products. Therefore, restrained.
