摘　　要：MTBE装置使用的催化剂一般为磺酸型二乙烯苯交联的聚苯乙烯结构的大孔强酸性阳离子交换树脂,本文对催化剂的失活原因进行分析,通过优化操作,降低原料中能够进行交换的杂质离子,降低原料中的碱类物质及含氨氮化合物,降低原料中的二烯烃、烯烃在树脂的微孔中聚合堵塞孔通道,延长了催化剂的使用寿命,实现了MTBE装置长周期平稳运行,提升了企业的经济效益。The catalysts used in MTBE devices are generally large pore strong acidic cation exchange resins with a sulfonic acid type divinylbenzene crosslinked polystyrene structure.This article analyzes the reasons for catalyst deactivation,and optimizes the operation to reduce impurity ions that can be exchanged in the raw material,reduce alkali substances and amine nitrogen compounds in the raw material,and reduce the polymerization of dienes and olefins in the micropores of the resin to block pore channels.The service life of the catalyst has been extended,achieving long-term stable operation of the MTBE device,and improving the economic benefits of the enterprise.
