Abstract
Liquid phase hydration of cyclohexene over faujasite, mordenite and ZSM-5 catalysts at 10 MPa and temperatures 150 - 210 °C in a batch system was studied. Influence of the type and Si/Al ratio of the zeolite on the conversion of cyclohexene and the selectivity to cyclohexanol formation was determined. Performance of the catalyst was also investigated through adsorption measurements of water and cyclohexene. Mordenite with the Si/Al ratio 70 provided the best results. The selectivity to cyclohexanol was 99% at the conversion of cyclohexene 27% at 200 °C after 4 h. All the catalysts were regenerated by calcination at 450 °C.
