Degradation of toluene in exhaust gas with plasma and nano-materials

Non-thermal plasma associated with nano-catalyst (made by myself) was used to degrade toluene under different electric field and packed materials. At the same time, the mechanism of toluene degradation using plasma and catalyst was discussed. Degradation of toluene increased with increase of electric field strength and decrease of flow velocity and initial concentration. There were four conditions in plasma without packed materials (1), with packed materials(2), with BaTiO₃ in the surfaces of packed materials(3), and with nano-materials Ba_0.8Sr_0.2Zr_0.1 Ti_0.9O₃(4). Degradation of toluene decomposition represented an obvious trend, that was, η(4)>η(3)>η(2)>η(l). The best removal efficiency of toluene arrived at 95%. The distribution ratio of energy showed as R(1)>R(2)>R(3)>R(4). As packed materials in reactor, nano-material could reduce power consumption on treating with the same quantity of toluene. Middle-of-the-products include aldehyde, alcohols amide, and benzene derivative were analyzed by GC-MS. If electric field strength was enough strong, the final resultants would be CO₂, CO and H₂O.
