KC系列耐硫变换催化剂应用总结
Application Summary of the KC Series Sulfur-Tolerant Shift Catalyst
摘要:

介绍了KC系列耐硫变换催化剂的物化性能、使用条件及其在500 kt/a合成氨、800 kt/a尿素项目上的应用情况。实际应用情况表明:KC系列耐硫变换催化剂的强度稳定性、变换活性、活性稳定性等综合性能优于国内同类耐硫变换催化剂;KC-103S型预硫化耐硫变换催化剂能大幅缩短开车时间并节约开车费用,降低了开车过程中变换催化剂床层超温的风险,而且储存、运输、装填等过程无需氮气保护,操作更加安全方便,避免了开车期间大量气体放空造成的资源浪费和环境污染。

Abstract:

The physical and chemical properties of KC series sulfur-tolerant shift catalyst, their using conditions and their application in 500 kt/a ammonia synthesis and 800 kt/a urea projects are introduced. The practical application shows that comprehensive performance of KC series catalyst such as strength stability, shift activity and activity stability, etc., is superior to domestic similar products. KC-103S presulfurization sulfur-tolerant shift catalyst can greatly shorten the start-up time, save start-up costs, and reduce the over-temperature risk of shift catalyst bed during start-up. The nitrogen protection is not requiement in the process of storage, transportation and loading of the catalyst, and the operation is more safe and convenient, avoiding resources waste and environmental pollution caused by the large amount of gas discharge during start-up.
