Abstract


In this study, new types of SO42-/TiO2-HBeta (ST/Hβ) catalysts are synthesized and characterized by XRD, IR, N2 adsorption-desorption, ICP-OES, SEM, and NH3-TPD methods. Conversion of 1-methylnaphthalene is carried out in a fixed-bed system. Based on the study’s results, the catalysts ST/Hβ showed uniform SO42-/TiO2 (ST) loading, high surface area, and sufficient mild acid sites. When ST content increased, the amount of strong acid sites and by-products decreased. Under atmospheric pressure, catalyst 15-ST/Hβ showed a catalytic performance of 74.1% conversion and 97.4% selectivity.
