A new type of zeolite beta (denoted as MB) with multi-pore system was synthesized by using in situ synthesized method from kaolin mineral in this study NiW/Al(2)O(3)-MB and NiW/TiO(2)-Al(2)O(3)-MB catalysts were prepared and the hydrodesulfurization (HDS) activities of these catalysts were evaluated with FCC diesel feed. The samples were characterized by N(2) physisorption, XRD. SEM, TPR. FT-IR spectroscopy of pyridine adsorption, HRTEM and XPS techniques The HDS results showed that the MB-containing catalyst exhibited much higher HDS conversion (98.7%) than that of NiW/gamma-Al(2)O(3) (97.5%) The incorporation of TiO(2) into the composite supports further increased the HDS conversion (99.3%) of NiW/TiO(2)-Al(2)O(3)-MB. The higher HDS activity was mainly associated with the appropriate ratio of B/L (Bronsted acid/Lewis acid) and the enhanced hydrogenation activity. (C) 2009 Elsevier B V. All rights reserved
