제목 Valuable hydrocarbons from methane via catalytic & noncatalytic ways
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. The existence of maximum conversion at a specific gap distance was experimentally observed and could be described successfully by using a newly developed concept of micro-electrodes. 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.
