【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.更多还原
