Numerical study on catalytic combustion of methane with ozone using Pd-exchanged zeolite X

Abstract

A steady-state 1D macro-homogeneous model is developed to illustrate the combustion process of methane with ozone in the reactor composed of Pd-exchanged zeolite X. The model is validated by comparing the predicted results with the measured data. The methane conversion increases with decreasing the inlet methane concentration and gas space velocity and increasing the inlet ozone concentration and temperature. As the reactor length reduces, the methane conversion varies little if the reactor is too long but decreases when the reactor is too short. Therefore, the reactor should be properly designed to balance costs and the methane-conversion efficiency.
