摘要: In this study, the catalytic effect of TiO2-ZnO/GAC coupled with non-thermal plasma was investigated on byproducts distribution decomposition chlorinated VOCs in gas streams. The specifi c input energy, and initial composition examined a corona discharge reactor energized by high frequency pulsed power supply. Detected by-products for NTP at 750 J L –1 included CO, CO2, Cl2, trichloroacetaldehyde, as well trichlorobenzaldehyde chloroform feeding, while they were dominated lower abundance Cl2 chlorobenzene introduction. Some such O3, NO, NO2, COCl2 disappeared totally over TiO2-ZnO/GAC. Furthermore, amount heavy products decreased signifi cantly favor small molecules hybrid process. selectivity towards COx soared up to 77% catalyst 100 ppm
