Abstract
In this paper titanium-zirconium mixed oxides with different molar ratio of Ti to Zr was prepared by improved sol-gel method. The supporters were characterized by means of BET, XRD methods, and the results showed that the TiO_2-ZrO_2 mixed supporter had much better specific surface, pore structure and textures properties than the single support or the mixed support prepared by the conventional sol-gel method. The crystal phase of the mixed supporter changed as the molar ratio of titanium to zirconium, which affected its catalytic activity. The hydrodearomatics performance of Pd-Pt/TiO_2-ZrO_2 catalyst was investigated on the fixed-bed reactor. The results indicated that the catalyst had excellent hydrodearomatics activities, and showed a stronger sulfur tolerance performance.关键词
