Synergism of Plasma and Catalyst on the Dehydrogenative Coupling of Methane

摘要

At atmoshperic pressure and ambient temeprature, 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. Experimetnal resutls ahve revealed that the synergism does exist, when positve corona within a suitable power erange and an intermediate pulse repection frequency (PRF) for a loaded γMn_2O/γ-Al_2O_3 catalyst were chosen. In respect to the mechanism approach, a tentative modle for general pathway was proposed to explain the role of plasma and catalyst partaking in the process of metance decomposition and C_2 products formation.
