The removal of VOC from air using EB, MW and catalyst - Laboratory plant results

Abstract

A new hybrid technique for the VOCs removal from gases, based on the combined use of EB induced NTP (non-thermal plasma), MW induced NTP and catalytic oxidation, named “EB+MW-plasma catalysis”, is presented. 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 reactors, and the important role of catalysts in the complete conversion to CO{sub 2} and H{sub 2}O. Our experiences shown that the two means of treating the gases are complementary: the catalytic oxidation in the presence of MW is efficient for high VOC initial concentrations and low flow rates while the exclusive use of the EB irradiation determines high decomposition efficiencies only in the case of very low concentrations of VOC but for large flow rates. Real synergistic effects between NTP and catalysis were obtained by introducing the catalyst into the irradiation zone. The main conclusion of this work is that the combined treatment EB+MW+catalyst improves both decomposition efficiency and oxidation efficiency. The EB+MW+Catalysis method demonstrated good results on a wide range of  More>>
