渭河彬州乙二醇项目耐硫变换催化剂的应用

Application of sulfur-tolerant shift catalyst in ethylene glycol project in Weihe Binzhou

根据陕西渭河彬州化工有限公司乙二醇项目原始开车过程中变换催化剂的使用情况,找出了影响变换催化剂使用寿命的因素,总结了变换催化剂从装填、开车,再到系统稳定的整个流程。结果表明:催化剂的装填堆密度、装填数量、升温硫化深度、导气过程,以及初期开车过程中的频繁开停车,均是影响变换催化剂使用寿命的关键因素。

According to the use of shift catalyst during the initial start-up of ethylene glycol project of Shaanxi Weihe Binzhou Chemical Corporation Ltd.,the factors affecting the service life of shift catalyst were found out,and the whole process of shift catalyst from loading,start-up to system stability was summarized.The results show that the loading density,loading quantity,temperature-increasing vulcanization depth,gas-conducting process,and frequent start-up and shutdown during the initial start-up are the key factors affecting the service life of shift catalyst.
