摘要

Toluene abatement through adsorption and then plasma oxidation using ZSM-5, ZSM-5-gamma-Al2O3 (Z-Al), ZSM-5-TiO2 (Z-Ti), ZSM-5-BaTiO3 (Z-Ba), and AgMn/ZSM-5-BaTiO3 (AgMn/Z-Ba) as adsorbents/catalysts was investigated. The efficiency of toluene removal reached similar to 100% for all the tested adsorbents/catalysts. ZSM-5 had the lowest mineralization rate (MR) of similar to 43%, while Z-Ba had the highest MR (88%) with an S-CO2 of similar to 80%. After loading AgMn onto Z-Ba, both the breakthrough capacity of toluene and S-CO2 was increased, while the production of byproduct O-3 and MR was decreased. The mixed materials created a higher amount of active species capable of deeply oxidizing adsorbed toluene.
