摘要： The present invention relates a metal passivator additive comprising: a rare earth component; alumina; clay; colloidal silica; and a zeolite having high silica to alumina ratio. The present invention also relates to a process for preparing a metal passivator additive, said process comprising: preparing a rare earth slurry by mixing rare earth component with water; obtaining an alumina gel by treating alumina slurry with an acid, wherein the alumina slurry is prepared by mixing alumina and water; mixing the alumina gel and the rare earth slurry to obtain a slurry mixture; adding a colloidal silica to the slurry mixture; preparing a clay slurry by mixing clay and a dispersant; combining the clay slurry and the slurry mixture to obtain a rare earth-binder-filler slurry; obtaining an additive precursor slurry by mixing a zeolite having high silica to alumina ratio to the rare earth-binder-filler slurry; spray-drying the additive precursor slurry to obtain a spray-dried product; and calcining the spray-dried product to obtain the metal passivator additive.

摘要： A composition of a value added RFCC catalyst and a process of preparation of a composition for a dual function additive catalyst from a spent catalyst are disclosed. The value added spent FCC catalyst offers improved performance, options such as either employing as an additive for passivation of both vanadium and nickel and enhancing catalytic activity, for initial start-up or make-up for attrition losses. The value addition process does not harm any of physical properties of starting material with respect to ABD, attrition index, surface area and particle size distribution. Value added catalyst can be used in a range from 1-99 wt % in fluid catalytic cracking process in which, feeds may have higher metals and carbon.
