摘要
Partial oxidation of methane(POM) co-fed with CO_2 to syngas in a novel catalytic BaCo_(0.6)Fe_(0.2)Ta_(0.2)O_(3-δ) oxygen permeable membrane reactor was successfully reported.Adding CO_2 to the partial oxidation of methane reaction not only alters the ratio of CO/H_2,but also increases the oxygen permeation flux and CH_4 conversion.Around 96%CH_4 conversion with more than 93%CO_2 conversion and 100%CO selectivity is achieved,which shows an excellent reaction performance.A steady oxygen permeation flux of 15 mL/(cm^2 min) is obtained during the 100-h operation,which shows good stability as well.
