| 摘 要： | 以Cu/ZSM_5为催化剂，在新型微波催化反应器上进行了微波协同催化分解NO反应.初步探讨了微波协同催化分解NO反应的宏观动力学，并与常规加热条件下催化分解NO反应的宏观动力进行了对比.计算结果表明：在微波辐射条件下，该反应的活化能为14.6 kJ/mol.而常规加热条件下，该反应的活化能为75.6 kJ/mol.微波辐射条件下该反应活化能仅仅是常规加热条件下该反应活化能的1/5.177.这说明微波作用不仅具有致热效应，而且大大降低了反应活化能，具有微波催化效应.

| Abstract: | The microwave synergistic catalytic decomposition of NO in a new microwave catalytic reactor with Cu/ZSM_5 catalyst was studied. The kinetics of catalytic decomposi_tion of NO under microwave synergistic condition was discussed,and has been compared with it under the conventional heating condition. The results indicate that：the activation energy of that reaction is 14. 6 kJ/mol under the microwave radiation conditions,while un_der the conventional heating conditions,it is 75. 6 kJ/mol. The activation energy of that re_action under conventional heating was 5 . 177 times higher than that under microwave heat_ing . According to these results,it has been proved that the microwave irradiation has micro_ wave catalysis effect besides thermal effect. |
