Mathematical Modeling of the Adsorption-Catalytic Process with Internal Heater in a Multisectional Arrangement

Sergey V. Zazhigalov,

Abstract: In this work, a multisectional reactor for the adsorption-catalytic process for the neutralization of emissions from volatile organic compounds (VOCs) was studied by the method of computational fluid dynamics (CFD) modeling using the COMSOL Multiphysics commercial software. The nonstationary model in a three-dimensional (3D) geometry considered the change in the velocity field, pressure, and mass balance, including in the pores of the catalyst pellets and the reactions on their inner surface, as well as the he… Show more

“…The implications on hydrogen consumption, reactor conditions, temperature rise, and catalyst selection, which are crucial for process optimization in diesel production, are discussed. The study of Zazhialov et al investigates a multisectional reactor for adsorption-catalytic neutralization of volatile organic compounds (VOC) emissions via computational fluid dynamics modeling. Analysis shows that system sectioning reduces peak temperature and VOC concentration during regeneration while increasing average VOC abatement.…”
