    Abstract

    Oxidative coupling of methane (OCM) on La 2O 3 semiconductor catalysts at 423 K external temperature was investigated. DC power supplied from two electrodes in a catalyst bed enabled stable and selective production of C 2H 6 and C 2H 4 over Sr-La 2O 3 (Sr/La = 1/200 and 1/20), but plasma reactions proceeded over other catalysts. The electrical conductivity of the semiconductor catalyst was important for controlling this reaction. A high yield of C2 (49% selectivity, 51.3% O 2 conversion) was obtained using 2.7 W of electricity at a lower external temperature (423 K).
