EFFECT OF MODIFIED INDUSTRIAL ZEOLITE-BETA ON ONE-STEP CATALYTIC HYDRATION OF PROPENE TO ISOPROPANOL

In order to improve the yield of isopropanol, we used a new type of ze olite beta catalysts, By using acid-exchange and steaming treatments, various types and contents of binder, different forming and exchanging conditions, we have studied the technological conditions for preparin g zeolite beta. As a result, we obtained a new kind of catalyst, Using XRD, SEM, LR, TPD, AAS, etc., we studied the effects of structure and acidity changes of modified zeolite beta on the reaction. The catalyt ic performance under industrial production conditions was studied. The IPA yield was from 9% to 10%, better than the value of 4% of the orig inal industrial catalyst. Under these circumstances, we scaled the exp eriment up at the Jinzhou Petrochemical Company and achieved good resu lts, opening up new industrial perspectives.
