抄録

Microwave heating can be considered as the regeneration method of adsorbent in the removal of very low concentration VOCs. In this study, the effect of addition of cobalt oxide on microwave heating of adsorbent bed was investigated. Oxidation of ethylene by Co-modified MORs under microwave irradiation was also tested. In the case of Co-modified MOR prepared by impregnation method, the addition of Co<SUB>3</SUB>O<SUB>4</SUB> did not have an effect on microwave heating. However the addition of Co<SUB>3</SUB>O<SUB>4</SUB> promoted microwave heating when Co<SUB>3</SUB>O<SUB>4</SUB> and NaMOR were mixed mechanically. In addition, pelletized mixture is heated to higher temperature with fast rate of temperature rising as compared with powder type mixture. In the case of the pelletized mixture with 75 wt% Co<SUB>3</SUB>O<SUB>4</SUB>, adsorbed water on NaMOR was almost desorbed during microwave irradiation. It was possible to remove ethylene on the pelletized mixture using microwave irradiation and obtain high conversion of ethylene over 93 %.
