摘要：
The OCM reaction in the presence of HCl over NaCl-MnO/H-ZSM catalyst at 750 degrees C has been studied. Effect of HCl partial pressure on the CH4 conversion and selectivities to principal products, also on the time-on-stream of catalyst has been examined. Addition of HCl into initial methane-oxygen mixture can increase selectivity to C2+ formation and ethene selectivity, in particular. It seems that the time-on-stream of this catalyst is nearly 35-40 h in the presence of HCl.
