EFFECTS OF HEAT AND MASS TRANSFER ON CATALYST PERFORMANCE IN NOx DEDUCTION REACTIONS

本文通过数值计算的方法,针对NOx气体在催化剂中的流动传热和反应传质情况进行理论分析,考察影响脱除 反应和过程的各因素,深入认识催化反应与传递耦合的基本物理现象,以及催化反应剂内部过程特性,揭示物理现象与过 程的基本规律,为催化剂设计、流道优化以及发应强化提供具有参考意义的理论依据。

A numerical simulation is conducted to investigate the performance of the catalytic reactions in the NOx SCR channels. The simulation results reveal some important factors/parameters affecting the catalytic reaction conjugated with the transport phenomena, particularly provide some theoretical evidences to understand the inner performance of NOx deduction inside the catalysts.
