摘要/Abstract

摘要： 为系统研究燃煤电厂SCR脱硝系统失活催化剂再生前后性能的变化，对比分析了某330 MW燃煤机组失活催化剂再生前后的微观特性。试验结果表明，由于再生时对催化剂活性组分进行了有效补充，再生后的催化剂活性有较大幅度提高；再生过程中消除了催化剂表面的硫酸盐沉积，增强了催化剂表面的弱酸和中强酸酸性位，同时基本保持催化剂的锐钛矿晶相，催化剂微观形貌恢复到疏松均匀状态。由此证明，采用添加活性成分、消除沉积盐的催化剂再生方法，可延长催化剂的使用寿命，降低电厂生产成本。

Abstract: In order to systematically study the performance of deactivated SCR catalyst for coal-fired power plant before and after regeneration, the microscopic characteristics of deactivated catalyst for a 330MW coal-fired unit are analyzed. The testing results show that after regeneration the active components of the catalyst after regeneration are effectively supplemented, and the catalyst activity is greatly improved. During the regeneration process, the sulfate salt deposition on the catalyst surface is eliminated and the weak acid and the strong acidity sites of the catalyst surface are enhanced, while the anatase phase of the catalyst is well maintained, and the microstructure of the catalyst is restored to a relaxed and even state. This proves that the catalyst regeneration method in terms of adding active ingredients and eliminating deposited salt can prolong the service life of the catalyst, and reduce the production cost of the power plant.

Key words: coal-fired power plant, SCR denitrification, deactivated catalyst, regeneration, micro-characteristics
