A new insight into self-support ray polarization (SSRP) of nonthermal plasma for benzene hydrocarbon decomposition in fuel exhaust was put forward. A wire-tube dielectric barrier discharge (DBD) AC plasma reactor was used at atmospheric pressure and room temperature. The catalyst was made of nano-TiO2 and ceramic raschig rings. Nano-TiO2 was prepared as an active component by ourselves in the laboratory. Ceramic raschig rings were selected for catalyst support materials. Then, the catalyst was packed into nonthermal plasma (NTP) reactor. Six aspects, benzene initial concentration, gas flux, electric field strength, removal efficiency, ozone output, and CO2 selectivity on benzene removal efficiency, were investigated. The results showed SSRP can effectively enhance benzene removal efficiency. The removal efficiency of benzene was up to 99% at electric field strength of 12 kV/cm. At the same time, SSRP decreases ozone yield and shows a better selectivity of CO2 than the single technology of nonthermal plasma. The final products were mostly CO, CO2, and H2O. Our research will lay the foundation for SSRP industrial application in the future.
