钯触媒在蒽醌法生产双氧水的应用

Application of palladium catalyst in hydrogen peroxide production by anthraquinone Process

根据国内双氧水生产装置上钯催化剂的使用情况,阐述了蒽醌法生产过氧化氢中所用钯催化剂的装填、活化、应用和再生等过程的优化控制和注意事项。提出了改善操作条件的办法,如温度、压力、工作液流量及循环氢化液流量等。提出了用蒸汽或有机溶剂使催化剂再生的方法。

According to the application status of palladium catalyst in domestic hydrogen peroxide production plant, the optimization control and attention matters of load, activation application and reactivation of palladium catalyst were discussed. The innovation measures of operation conditions were put forward, for example, temperature, pressure,operation fluid flow and circulating hydrogenated liquid flow. Catalyst reactivation method with vapor ahd organic solvent were put forward.
