  • PROCESS FOR ENHANCING NICKEL TOLERANCE OF HEAVY HYDROCARBON CRACKING CATALYSTS
    Publication number: 20140235429
    Abstract: The invention discloses a process for upgrading feed streams containing residual fractions with high concentrations of metals, more specifically nickel content up to 150 ppm employing acidic catalysts comprising large pore rare earth faujasite zeolite component, pentasil zeolite component and pseudoboehemite containing resid cracking component while the composite is impregnated with lanthanum oxide or aluminium oxide or mixture of both. The hydrocarbon feed stock can be sourced from either petroleum derivatives or from coal, tar or sand. The process results in increased selectivity of propylene in LPG in the range of 39-52%.

  • VALUE ADDED SPENT FLUID CATALYTIC CRACKING CATALYST COMPOSITION AND A PROCESS FOR PREPARATION THEREOF
    Publication number: 20130168290
    Abstract: 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.
