VOCs REMOVAL BY COMBINED USE OF ELECTRON BEAM, MICROWAVE AND CATALYST

摘要

A new hybrid technique for the volatile organic compound decomposition, based on combined use of electron beam (EB) induced non-thermal plasma (NTP), microwave (MW) induced NTP and catalytic oxidation, named "EB+MW-plasma catalysis", is presented. Real synergistic effects between NTP and catalysis were obtained by introducing the catalyst into the irradiation zone, i.e. into the MW reactor or EB reactor. The main goal of our research was to combine the features of each known technique used in gas pollution control, i.e. the very high efficiency of EB in converting VOCs to intermediate products, the ability of MW to produce and sustain NTP in large electrodeless reaction vessels, and the important role of catalysts in the complete conversion of the intermediate products to carbon dioxide and water.
