活性炭引发的常压连续微波放电下甲烷转化制C_2烃

CONVERSION OF METHANE TO C_2 HYDROCARBONS VIA ACTIVE CARBON INDUCED CONTINUOUS MICROWAVE DISCHARGE UNDER ATMOSPHERIC PRESSURE

考察了活性炭引发的常压微波连续放电下甲烷转化制C2 烃的过程。活性炭及氩气的存在有利于常压连续微波放电的生成。在这一过程中甲烷转化的主要产物为乙炔。随着停留时间的缩短及甲烷浓度的减小甲烷的转化率降低而乙炔和乙烯的选择性基本保持不变。氩气易在微波场下放电 ,促进了甲烷的转化和乙炔的生成。

The process of conversion of methane to C 2 hydrocarbons via active car bon induced continuous microwave discharge under atmospheric pressure was invest igated. The presence of active carbon and argon was advantage to the formation o f continuous microwave discharge under atmospheric pressure. The main product of this process was acetylene, and methane conversion decreased with decreasing me thane content and decreasing resident time, while the selectivity of acetylene a nd ethylene remained unchanged. Argon was a good discharger in microwave field and facilitated the conversion of methane and production of acetylene.
