摘要：
In this study, new types of SO42-/TiO2-HBeta (ST/H beta) catalysts are synthesized and characterized by XRD, IR, N-2 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/H beta 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/H beta showed a catalytic performance of 74.1 % conversion and 97.4 % selectivity.
