摘　　要：合成氨装置高温变换炉由轴向流结构改为轴径向流结构,解决了床层阻力上涨快的问题。由于轴径向流结构不能有效监控催化剂热点温度移动,对催化剂活性的判别主要依照出口CO含量变化。通过对高温变换炉内件改造情况,使用B113-2型催化剂性能参数、还原过程及运行进行综合分析,证明B113-2催化剂低温活性较好,总结使用后的经验并提出建议,以便进一步指导高温变换催化剂的使用。With the change of axial-flow structure of high-temperature reformer in ammonia plant to radial-flow structure an issue of quick rise of bed resistance is solved. As the axial-radial flow structure can not effectively monitor the hot point temperature migration of catalyst, the distinction of catalyst activity is mainly in accordance with the change of CO content at outlet. With a comprehensive analysis of the retrofit of high-temperature shift converter internals ,reduction process and running by adopting the performance parameters of B 113-2 catalyst, it has proved that a low-temperature activity of B113-2 catalyst is better. The experiences after the catalyst use is summarized and suggestions proposed for a further instruction in the use of high-tem- perature shift-conversion catalyst.
