Synergism of Plasma and Catalyst on the Dehydrogenative Coupling of Methane

Abstract

At atmospheric pressure and ambient temperature. pulse corona induced plasma was used as a new method for dehydrogenative coupling of methane. The synergism of plasma and catalyst on dehydrogenative coupling of methane was investigated. Experimental results have revealed that the synergism does exist, when positive corona within a suitable power range and a n intermediate pulse repetition frequency (PRF) for a loaded y-bh203/y-A1203 catalyst were chosen. In respect to the mechanism approach, a tentative model for general pathway was proposed to explain the role of plasma and catalyst partaking in the process of methane decomposition and Cz products for mati on.
