Abstract:  The effect of Si/Al ratio of the starting NaY on hydro-upgrading catalyst performance for LCO was studied. Y type zeolite modified from higher Si/Al ratio of the starting NaY also had higher framework Si/Al ratio. Three catalysts of W-Ni supported on different modified Y type zeolites and Al2O 3 were prepared by impregnation method. The catalysts were characterized by XRD, BET, DRS and HRTEM, and evaluated with a micro-reactor using tetralin as a model compound and a 100 ml hydrogenation test unit using FCC LCO as feedstocks. By contrast, tungsten supported on Y type zeolite modified from higher Si/Al ratio of the starting NaY zeolite had more type II active phase and WS2 is highly stacked, exhibiting the weak interaction with Al2O3 and should have higher activity. The revaluation results revealed that the catalyst prepared by higher Si/Al ratio of the starting NaY zeolite has higher tetralin conversion and better hydro-upgrading performance for FCC LCO. © 2010 Elsevier B.V.
