Kinetic Model of Nitric Oxide Reduction on CuFe/SUZ-4 Catalyst in Packed Bed Column

P. Worathanakul, T. Layakul, and P. Juengsura
Abstract—Model was predicted for suitable condition to achieve the maximum nitric oxide (NO) conversion for using with even-CuFe/SUZ-4 zeolite catalyst in packed-bed reactor in NO reduction. Comsol Multiphysics and Reaction Engineering Lab3.5a based on Computional Fluid Dynamics (CFD) were used to evaluate performance of the reactor. The simulation results were according to the experiments in different sequence of Cu and Fe loadings on SUZ-4 zeolite with impregnation method. Volume flow rate, preheat temperature, and reactor temperature of gas feed rate were used as variables for finding the maximum NO reduction. The results show that the maximum NO conversion of CuFe/SUZ-4 catalyst can achieve at 500°C reaction temperature with 250 ppm of 250 °C preheat temperature gas feed rate. To increase NO conversion, decreasing of gas feed flow rate is the main effect than decreasing of preheat temperature. Moreover, the simulation results were closed to the experiments with only 0.12-1.55 % of error.

Index Terms—CuFe/SUZ-4 zeolite, nitric oxide, kinetic model, catalyst.
