Abstract:
An external magnetic field has been proven to be effective for application in catalytic reactions as it improves the catalytic performance and reduces activation energy through enhancing specific gas adsorption and gas-solid interaction. In this work, carbon dioxide (CO2), a major greenhouse gas, was used as a reactant gas for BTX (benzene, toluene, xylenes) production via catalytic reforming reaction. In order to improve catalytic performances both for CO2 conversion and BTX selectivity, the external magnetic field has been applied to facilitate diffusionadsorption capacities of reactant gases over the catalysts and therefore activation energy. To promote CO2 reforming reaction under external magnetic field, FexOy/ZSM-5 catalysts with intrinsic magnetic properties and limited space for diffusion were therefore chosen to create such a mechanism. As the iron oxide phases strongly affect the catalytic performance, in order to understand the effects of external magnetic field on every parameter according to the control parametersincluding characteristics of mass transfer within confined pore spaces of catalysts. We therefore firstly investigated the diffusion phenomena of reactant gas, it was found that the CO2 reactant gas interacts with ZSM-5 zeolite, and therefore takes a longer time to diffuse through the ZSM-5 zeolite compared to the inert silica, while H2 takes less time than CO2. Moreover, to understand and confirm the effects of an external magnetic field on the catalytic performance, an external magnetic field will be applied over the catalytic packed-bed reactor. The results will be compared to those without magnetic field.
