摘要: 通过工业试验,考察了钛硅分子筛HTS-1新剂和再生剂在环己酮氨肟化制备环己酮肟工艺中的工业试验性能,工业运行结果显示:环己酮转化率>99.6%,环己酮肟选择性>99.5%,催化剂单程寿命大于600 h。同时介绍了亚微米级HTS-1催化过程中的分离和粘壁问题及其工程解决措施,应用陶瓷膜微滤技术解决了催化剂和反应液的分离和循环使用问题,应用波纹管技术克服了催化剂粘壁现象,达到正常换热的效果,并通过优化使系统满足生产要求。

Abstract: Through industrial trials for cyclohexanone-oxime synthesis catalyzed with molecular sieves HTS-1,the activity and the life of fresh and regenerated HTS-1 catalysts have been investigated. The running results showed that the conversion of cyclohexanone was above 99.6%,and the selectivity for cyclohexanone oxime was above 99.5%,and the single circle life of HTS-1 was no less than 600 h. The separation and on-line recycle of HTS-1catalyst were achived through ceramic microfiltration,and the wall-sticking problem of HTS-1 catalyst was resolved through a technology of corrugated tube heat exchange.
