【摘要】 在不使用催化剂,吸收剂的环境友好条件下,利用大气压介质阻挡强电离放电加速电子及激励气体分子方法,将CH₄和CO₂气体激发、电离和离解成CH₃,CH₂,CH,H,CO,O,OH 等活性粒子,并在非平衡等离子体反应器内重新组合,生成合成气、气态烃及含氧有机物醇、酸等有价值产物,甲烷的转化率高达60%以上,二氧化碳或氮气的加入使甲烷的转化率有明显提高,甲烷与二氧化碳反应气的最佳体积比为3/1.当甲烷体积分数为75%时,可得到H₂/CO 摩尔比为3的高质量的合成气,收集到的液体产物主要有醇、酸和水等.更多还原

【Abstract】 CH₄ and CO₂ can be excited,ionized and dissociated into active particles such as CH₃,CH₂,CH,H,CO,O and OH et al.by the dielectric barrier strong ionization discharge at atmosphericpressure.These particles can recombine each other in the reactor to form valuable products includingsyngas,gaseous hydrocarbons and oxo organic compounds without catalyst and absorbent,theconversion rate of CH4 reached up to 60%,and it can be increased evidently in the presence of CO₂ andN₂.The optimum feed ratio of CH₄/CO₂ iS 3/1.If CH₄/CO₂ iS 75% by volume,the high qualitysyngas with n（H₂）/n（CO）=3 can be obtained by the technique.Main components of liquid products arecarbinol,ethanol,acetic acid and water.更多还原
