Parametric Study of Thermal Flow-Reversal Reactor for Ventilation Air Methane Oxidation

Abstract:

Experimental studies of ventilation air methane oxidation were carried out in a thermal flow-reversal reactor and a fixed bed reactor in laboratory scale respectively. The reaction characteristics of ventilation air methane in a fixed bed reactor were investigated. The influence of the feed gas velocity and the lean methane concentration on the temperature profile in the thermal flow-reversal reactor was studied. The internal temperature uniformity of the cross section and the cavity of the flow-reversal reactor which have influence on lean methane conversion have also been discussed and analyzed. The results shows that the oxidation of lean methane needs to meet the ignition temperature condition and the residence time condition, and the temperature distribution in the thermal flow-reversal reactor is mainly related to the methane concentration and the feed gas velocity while the methane conversion rate is mainly related to the temperature and the residence time in the high temperature zone of the reactor.
