초록 Valuable hydrocarbons such as ethylene, acetylene, aromatics and hydrogen could be synthesized via a non-thermal plasma bed and a thermochemical catalytic bed. In the first reaction step, a dielectric barrier discharge (DBD) plasma reactor was employed for non-oxidative coupling of methane. The coupling reaction in the DBD plasma bed was conducted near atmospheric pressure and room temperature. This non-catalytic reaction system could successfully activate C-H bond to produce methyl radicals and light hydrocarbons. It seemed quite possible to control the compositions of ethane, ethylene, and acetylene by properly adjusting the size or the gap distance of particles. The obtained C2 chemicals could be fed into the second thermochemical reactor, where aromatization take place. With novel hierarchical zeolite-based catalysts, the effects of structural difference as well as the Si/Al ratio were scrutinized. The recent progress on the conversion technology will be shared.
