Methane, oxygen and H_2O molecules are activated, ionized and dissociated into active particles such as CH_3~+, O~-, H_2O~+, CH_3, CH_2, CH, H,OH and O, by nonelastic collision with high energy electrons. The particles react with each other in the reactor to synthesize chemically products including gaseous oxy-hydrocarbons.We study the rule of reaction by changing electrical parameter, gas flow etc. Study the conversion of methane, selectivity of gaseous hydrocarbons and yield of methanol under different reaction condition.

针对常规甲烷催化转化和氧化偶联制备含氧化合物的问题，遵循国际化学科学研究前沿"绿色化学"原则，采用自然界存在丰富的CH_4、H_2O和O_2为原料，在绿色友好的常温大气压无任何催化剂的条件下，采用强电场电离放电加速电子及其激励气体分子的极端物理手段，在反应腔体内进行无任何环境污染的非平衡等离子体化学反应，将气体分子激发、电离、离解成CH_4~+、CH_3~+、CH_4~·、H_2O~+、H_2O~·、O_2~+、O(~1D)等活性粒子，生成气态烃及含氧碳氢化合物，整个反应过程实现零污染、零副产品。
