针对温室气体CH_4和CO_2化学利用,提出介质阻挡气体放电等离子体化学转化方法,将CH_4,CO_2直接转化为高碳烃,并副产一部分合成气。实验表明,介质阻挡气体放电CH_4和CO_2反应烃类产物类似于常规催化的Fischer-Tropsch(F-T)合成,包括气态烃、液态烃和高聚物,但产物分布不符合Flory-Schulz分布。研究讨论了分子筛在抑制等离子体聚合物和炭黑生成方面的作用,讨论了CO_2进料对CH_4转化制高碳烃的影响,指出适宜进料CH_4/CO_2比在2/1至3/1范围内。
In view of the chemical utilization of CH_4 and CO_2 in greenhouse gases, a new method of chemical conversion of gas barrier plasma by plasma is proposed. CH_4 and CO_2 are directly converted into high-carbon hydrocarbons and some of the syngas is by-produced. Experiments show that the gas barrier CH_4 and CO_2 reaction products are similar to the conventional catalytic Fischer-Tropsch (F-T) synthesis, including gaseous hydrocarbons, liquid hydrocarbons and polymers, but the products do not fit the Flory-Schulz distribution. The effects of molecular sieves on the inhibition of plasma polymer and carbon black formation were discussed. The effects of CO 2 feed on the conversion of CH 4 to higher hydrocarbons were discussed. It was pointed out that the optimum feed CH 4 / CO 2 ratio was in the range of 2/1 to 3/1 Inside.
