Transcripción del resumen del autor. In this study, a monolithic honeycomb catalyst is being used in a SCR reactor rather than pellet catalyst in many conventional gas-solid catalytic processes because the advantages of honeycomb matrix are very low pressure drop, high geometric specific surface area, and resistance to deposition of carbon and dust. The three-dimensional computational fluid dynamics (CFD) simulation for SCR for NO removal in monolithic honeycomb reactor was performed. The mathematical model of monolithic SCR reactor, in which a Rideal-type DeNOx rate equation was incorporated, was established. The calculated results were compared with the experimental data to verify the reliability. It was found that the lower gas inlet velocity, higher gas inlet temperature, and higher NH3/NO feed ratio lead to higher NO conversion. The square shape of the monolith channel has a better performance both in NO conversion and pressure drop. The appropriate space length between two catalyst layers under the investigated conditions is about 60 mm, which can result in good NO conversion and gas mixing.
