Temperature Dependence of Toluene Decomposition Behavior in the Discharge–Catalyst Hybrid Reactor

Abstract

The temperature dependence of toluene decomposition behavior was investigated with a two-stage discharge and ozone-decomposition-catalyst hybrid reactor. Toluene conversion jumped by four times by adding catalyst to the discharge at ambient temperature. This synergistic effect diminished with an increase in temperature, and no synergy was observed at higher than 200degC. In the hybrid reactor, CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">x</sub> formation was promoted compared to discharge alone irrespective of temperature, and toluene was completely oxidized to CO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">x</sub> at higher than 100degC. Ozone acts as the precursor of the key oxidants in the toluene decomposition.
