From the point view of product distribution, conversion of dimethyl ether and energy consumption, with RCD plasma DME conversion was higher and was hardly affected by the residence time of dimethyl ether, and hydrogen, carbon monoxide and unsaturated hydrocarbons with RCD plasma were more than those with DBD plasma.There was no liquid product with RCD plasma, but the liquid product obtained with DBD plasma consisted of aldehydes, alcohols and methoxy-containing organic compounds, for instance, formaldehyde, methyl alcohol, dimethoxy ethane and so on.Moreover, most compositions of liquid product were methoxy-containing compounds, and the liquid product selectivity was as high as 32.23%.However, energy consumption for the reaction with DBD plasma was more than that with RCD plasma.

从产物分布、转化率及能耗上看，利用RCD所获得的二甲醚的转化率高，几乎不受二甲醚停留时间的影响，且氢气、一氧化碳和不饱和烃的含量大，几乎没有液相产物，而利用DBD能获得较多的液相产物，包括一些醇、醛和含有甲氧基的有机化合物，如甲醛、甲醇和二甲氧基乙烷，且大部分组成都是含有甲氧基的化合物，液相产物的选择性高达32.23％，但是能耗较大。
