摘要：Regenerative catalytic oxidizers (RCO) are widely used to remove volatile organic compounds (VOCs) due to their energy-saving and stability. In this study, a multi-component catalytic reaction model was constructed to numerically investigate the reaction process of hydrocarbon-containing VOCs in RCO using computational fluid dynamics (CFD) simulation. To obtain the conversion characteristics of multicomponent hydrocarbons, the effects of intake load, equivalence ratio, and the composition of multicomponent hydrocarbons on the flow, heat transfer, and conversion rate of the reactor were analyzed. A feasibility study plan targeting the hard-to-convert components was also proposed. The results indicated that as the load increases, the conversion rates of the various components decrease, while the reaction rates increase. Moreover, increasing the flow velocity intensifies turbulence and enhances the collision frequency between the gas and the wall surfaces. This, in turn, amplifies the resistance effect of the porous medium. As the equivalence ratio of VOCs to oxygen increases, the oxygen-deficient condition leads to a decrease in the molecular weight of the hydrocarbons involved in the reaction. The reaction temperature also shows a downward trend. A comparative analysis of the catalytic combustion characteristics of multi-component VOCs and single-component gases reveals that adding ethane and propane can facilitate methane oxidation.
