文摘

Bioresources, such as landfill gas and agricultural residues, attract considerable attention because of growingconcerns of global energy and environmental protection. However, the efficient usage of bioresource posesmajor challenges and generally necessitates appropriate pre-reforming processes. We propose a low-temperature(300-500 C) upgrading method using an atmospheric pressure nonthermal discharge generated in a reformingcatalyst bed reactor for profitable recovery of poor bioresources. Excited species produced by high-energyelectron impact, which proceed independent of the temperature, accelerate methane steam reforming at lowertemperatures than normal catalyst reactions with minimum energy required. The resultant hydrogen-enrichedbiogas is then available for use in conventional energy utility systems, such as internal combustion engines.This paper introduces fundamental characteristics of nonthermal discharge and the catalyst hybrid reactor.Furthermore, a detailed mechanistic study of synergistic effects between nonthermal discharge and the reformingcatalyst is presented on the basis of the Arrhenius plot method.
