Abstract: The effect of crystal size of USY zeolite on the hydro-upgrading catalyst performance for FCC (Fluid Catalytic Cracking) LCO (Light Cycle Oil) was studied. Three catalysts of W-Ni supported on different crystal size USY zeolites and Al2O3 were prepared by impregnation method. The catalysts were characterized by XRD, and BET methods, and evaluated with a micro-reactor using tetralin as a model compound and a 100mL hydrogenation test unit using FCC LCO as feedstocks. By contrast, catalyst made from smaller crystal size USY zeolite had higher external surface area and shorter pore length, having more hydrogenation activity sites and short time contact of reactant molecules with acidity sites. The revaluation results showed that the catalyst prepared by small crystal size USY zeolite has higher tetralin conversion and better hydro-upgrading performance for FCC LCO.
