环己醇装置水合催化剂流失原因的分析

Analysis on reason of running off for cyclohexene hydration catalyst in cyclohexanol unit

分析了环己烯水合催化剂流失的原因,结果表明:搅拌器转速、催化剂浓度、催化剂界面是影响催化剂流失的主要原因,催化剂的再生、劣化也是影响催化剂流失的原因;工艺优化条件:反应温度120℃,压力0.5MPa、搅拌器转速45r/min、催化剂质量分数20%、催化剂界面10%。工艺优化改进后效果显著。

This paper analyzes the causes of running off for cyclohexene hydration catalyst.Rotation rate of agitator,concentration and interface of the catalyst are major factors,and crystal regeneration and deterioration of the catalyst are also factors.Wherefore,we optimize processing conditions shown as follow:reaction temperature 120℃,pressure 0.5MPa,agitator rotation rate 45r/min,catalyst concentration 20%,catalyst interface 10%.As a result,the effect is remarkable.
