摘要：

Oxidative methane coupling and the related chemical reactions have been studied in an electrochemical membrane cell of the type: CH4,(O2), SrFeO3-delta, Au/8%Y2O3 : ZrO2/Ag, air. The results are compared to a fixed bed study of SrFeO3-delta. The C2+ selectivity and the alkene/alkane ratio may be higher in the cell reactor than in the fixed bed reactor, but the C2+ yield never exceeded fixed bed data. The maximum C2+ Yield observed in the cell reactor was 3.1%. The electric fields in the cell when electrodes were connected influenced the selectivity to CO2 in a manner which may be related to the NEMCA effect.
