考察了常温常压脉冲电晕等离子体作用下金属氧化物对甲烷脱氢偶联反应的催化作用 ,观察到不同催化剂在脉冲电晕等离子体作用下的催化活性差别很大 ,且对 C2 产物的分布具有一定的调变作用 .γ-Mn2 O3/γ-Al2 O3催化剂的 C2 烃收率较空白载体提高了近 2倍 ,C2 烃选择性提高 3 0 %以上 ,该催化剂与脉冲电晕等离子体的结合可使其能量效率提高 2倍以上 .提出了一种等离子体催化作用促进甲烷脱氢偶联反应的初步模型 .
The catalytic effect of metal oxide on methane dehydrogenation coupling reaction under pulsed corona plasma was investigated. It was observed that the catalytic activity of different catalysts under pulsed corona plasma varied widely, The yield of C2 hydrocarbon of γ-Mn2 O3 / γ-Al2 O3 catalyst increased nearly twice as that of the blank carrier and the selectivity of C2 hydrocarbon increased more than 30%. The catalyst was in good agreement with pulsed corona plasma Can improve its energy efficiency by more than two times.A preliminary model for promoting the dehydrogenation of methane by plasma catalysis is proposed.
