The reforming of CH_4 with CO_2 for syngas production over the activated carbon under microwave irradiation
Abstract：The microwave-assisted heating apparatus was employed to study the reforming of CH4 with CO2 over activated carbon.The influences of microwave power and CH4/CO2 molar ratio on reforming reaction were investigated.Furthermore,catalytic activity of the activated carbon was tested.And specific surface area analysis and Bothem titration method were used to explore the possible reason for the deactivation of activated carbon.The results indicate that increasing microwave power or decreasing the CH4/CO2 molar ratio can result in an increase in the reactant gas conversions as well as in the content of syngas,together with a decrease in the molar ratio of H2 and CO.It is found that an encouraging catalytic activity is achieved at the beginning,followed by a sharp loss of catalytic activity after 40 min,which is mainly caused by the change of pore structure and the reduction of functional oxygen groups.
