摘要
Abstract
The traditional thermal catalytic conversion of methane requires harsh reaction conditions,while high-energy electrons in plasma can collide with methane molecules to generate radicals at low temperatures,leading to the formation of C2 hydrocarbons and hydrogen through recombination reactions.Dielectric barrier discharge(DBD)plasma-assisted non-oxidative coupling of methane has become a potential technology for high-value utilization of methane due to its simple reactor structure and uniform electric field distribution.The research progress on DBD plasma-assisted non-oxidative coupling of methane technology was reviewed,the activation mechanism and reaction pathway of methane in plasma systems were elucidated,and the key factors affecting methane conversion rate and product selectivity were analyzed from the perspectives of reactor structure,process parameters and catalysts.It points out that the activation mechanism of methane,the synergistic effect between plasma and catalysts,as well as the optimization of reactor structure and process flow,are important research directions for the future.This can provide a reference for the research on methane conversion technology.关键词
