VOCs Decomposition Using Multiple Catalysis in Non-Thermal Plasma Processing

Abstract:

A series of experiments were performed for toluene removal from a gaseous influent at normal temperature and atmospheric pressure by adsorption & non-thermal plasma strength & nano-catalysis technology. Non-thermal plasma was generated by dielectric barrier discharge. Sorbent & nano-catalyst were called combined catalyst which included MnO2/γ-Al2O3 and nano-Ba0.8Sr0.2Zr0.1Ti0.9O3 catalyst. MnO2/γ-Al2O3 has an advantage for ozone removal, while nano-Ba0.8Sr0.2Zr0.1Ti0.9O3 is a kind of good material for improving energy utilize rate. The results showed the synergistic technology resulted in greater enhancement of toluene removal efficiency and energy efficiency and a better inhibition for O3 formation in the gas exhaust. Based on data analysis of FT-IR, the experiment discussed decomposition mechanism and reaction process of toluene. The results showed that synergic effect could control byproducts effectively.
