摘要：
Effect of pore structure of silica support on sulfur tolerance and tetralin hydrogenation activity of Pd, Pt and Pd-Pt catalysts was investigated. Pore diameter of SiO2 supports affected the sulfur tolerance of noble metals and resulting hydrogenation activity. High sulfur tolerance and tetralin hydrogenation activity were observed for the Pd-Pt and Pt catalysts supported on SiO2 having the average pore diameter of 3 nm. This sulfur tolerance was comparable to those supported on ultra stable Y (USY) zeolite having the SiO2/Al2O3 ratio of 390.
