Abstract: H-β zeolite modified Pd/Al2O3 catalysts were prepared by impregnation. Effects of adding method and content of H-β zeolite on the catalytic performance were studied by XRD, BET, NH3-TPD and other analytical characterization techniques, as well as the reaction system with methyl oleate as model compounds studied. The results showed that the interaction among the components of Pd-Al2O3-BEA catalyst has a great difference because of the different adding method of H-β zeolite, thus its catalytic properties were greatly different. In the Pd/(BEA-Al2O3) catalysts, with H-β zeolite amount increased, its specific surface area, pore volume, acid amount of strong acid site all showed a trend of increase, while acid amount of weak acid site was first increased and decreased then, and the average pore size was decreased. Pd/(45% BEA-Al2O3) catalyst has the largest jet fuel-range hydrocarbons selectivity, branched alkanes selectivity, a certain proportion of naphthenes and aromatics, since it has an appropriate pore size distribution, moderate amount of strong acid site, the biggest amount of weak acid site. |
