Abstract:
The effect of microwave irradiation on an Ag/alpha-Al2O3 catalyst for ethylene epoxidation with silver particle sizes of 100-10 000 Angstrom and the average size 2000 Angstrom was examined. It was found that, on the catalyst preliminary reduced with hydrogen, the reaction rates toward both epoxidation and carbon dioxide formation considerably increased under exposure to a microwave field. This effect gradually decreased or even disappeared as the catalyst attained a steady state. A quantitative estimation of microwave absorption by the catalyst demonstrated that the effects associated with heating can be neglected. It was suggested that the reason for the observed phenomenon can be the modification of the catalyst electronic properties under exposure to microwave irradiation.
