“…Once the solid reaches to its operational temperature the catalytic reaction get initiated and due to the heat released by this reaction, the rate of reaction increases. About 50% of the conversion is observed at about a temperature of 504 K. The simulated results have been compared with those by [1] as shown in Figure 6. This shows that at a particular location as time increases, the conversion increases due to the catalyst reaction as the catalyst temperature increases.…”

Modeling for catalytic oxidation of a volatile organic compound, acetaldehyde for the purpose of controlling tail-pipe emissions from vehicular exhaust was carried out. The model developed was one-dimensional unsteady state model, using mass and energy balance equations to predict results for acetaldehyde conversion in an adiabatic monolith operating under warm-up conditions. The equations consisted of a set of partial differential equations that are coupled and solved using Backward Implicit Scheme. Analysis of the behavior of the converter during warm up period was carried out and it was observed that the warm up was faster for a fresh catalyst and this warm up period could be reduced by introducing hot incoming exhaust gas at higher temperature.

“…Combustion catalysts are based on transition metal oxides [2][3][4] or supported noble metals on inorganic supports [5][6][7]. In the design of combustion catalysts, it is well known that noble metals are more active and selective than transition metal oxides, and consequently lower reaction temperatures can be used.…”

This work focused on the mathematical model establishment and accurately forecast the conditions of thermal storage catalytic combustion about ethyl acetate, using platinum/palladium molecular sieve support reaction system. According to the physical properties of ethyl acetate and the mass transfer and continuity equations, a mathematical model was established using FORTRAN programming. The mathematical model was used to calculate the removal rate of ethyl acetate at switching time and processing flow rate. Under the same conditions, the model and experiment proved that the removal rate of ethyl acetate was above 98%, indicating that the model provides a valid data for a deeper understanding of the thermal storage catalytic combustion. The accuracy of the model is verified by the experimentally measured bed temperature when compared with the calculated. This work can provide a valuable tool to prevent the reactor from ‘over temperature' or ‘flaming out' in thermal storage catalytic combustion process.
