【 摘 要 】

In order to remain competitive, it is important to constantly optimize processes. The catalytic hydration of cyclohexene to cyclohexanol appears to be a promising alternative in the production of adipic acid. In this paper, the HZSM-5 was successfully synthesized without an organic template. Prepared H-ZSM5 catalysts were characterized using several techniques like X-ray diffraction (XRD), ammonia temperature-programmed desorption (NH3-TPD) and Scanning electron microscopy (SEM). Prepared H-ZSM5 catalyst was found to offer the best performance regarding selectivity and activity. The conversion of cyclohexene reached to 12.38% and the selectivity of cyclohexanol was 99%.
