摘　　要：针对三聚氰胺催化剂活性随使用时间的延长而降低的问题,进行了常压法三聚氰胺催化剂的活化探索。介绍了催化剂的活化原理及三聚氰胺催化剂的活化过程。生产实践表明,使用定量蒸汽和空气吹扫流化床反应器内的催化剂,可明显降低催化剂的堆积密度,进而改善催化剂的活性,提高三聚氰胺的转化率。With reference to the problem that the activity of melamine catalyst was decreased with the time, the activation of melamine catalyst in the atmospheric pressure process was explored. The catalyst activation principle and melamine catalyst activation process were described. The result showed that the use of quantitative steam and air to purge the catalyst in the fluidized bed reactor could reduce the bulk density of catalyst obviously and enhance its activity, and then improve the conversion rate of melamine.
