【 摘 要 】

References(11)The reforming of methane by carbon dioxide and the simultaneous permeation of hydrogen through a 0.1 mm thick palladium–silver alloy (25% Ag) have been carried out in a dielectric barrier discharges (DBDs) membrane reactor at room temperature and atmospheric pressure for the first time. In this study, the effects of feed ratio (CH4/CO2 ratio) and input energy density (flow variation and power variation) on reagent conversion, product selectivity, and specific energy requirement as well as separation efficiency were investigated. Carbon dioxide and methane conversions were enhanced by increasing the input power and decreasing the total flow rate. The H2/CO ratio could be controlled and depended on the concentration of CO2 in the feed gas. Further, the input energy density hardly influenced synthesis gas composition (H2/CO). The heat generated by DBD was used to separate pure hydrogen from the product stream by passing it through a Pd–Ag membrane.
