碩士 === 明道大學 === 材料科學與工程學系碩士班 === 97 === A microwave/Fe3O4 catalytic system was chosen for treatment of volatile organic compounds (VOCs). The system comprises a homemade microwave oven modified as the reactor in this study, which was fitted with a vertical, cylindrical quartz reactor comprising a catalytic packed column filled with granular Fe3O4, a microwave catalyst of iron (II, III) oxide. Experimental results showed that the destruction and removal efficiency (DRE) of isopropyl alcohol by microwave/Fe3O4 system reached to 99%, and the temperature of the catalytic packed column increased rapidly and reached thermal balance within 20-25 min. Analysis of the flue gas after combustion showed that most of the isopropyl alcohol was thermal oxidized into CO2 and H2O. The successful application of the microwave/Fe3O4 system on treatment of isopropyl alcohol will supply a new technology for treatment of VOCs.
