Abstract: As the core of denitration system, the performance of SCR catalyst directly affects the denitration efficiency of the system, but in the actual operation process, the catalyst will be slowly inactivated, and the catalyst life determines the operation cost of denitration system. On-line prediction of SCR catalyst life can help the power plant grasp the deactivation degree and remaining service life of the catalyst in time, which is conducive to improving the economy and stability of the system. According to the actual change of ammonia nitrogen mole ratio during the reaction, an on-line evaluation method of SCR catalyst life is proposed in this paper. By analyzing the physical and chemical properties and some operation data of SCR catalyst in a coal-fired power plant, an on-line prediction curve of SCR catalyst life is drawn, and the accuracy of the evaluation method is verified.
