Claims16
A composition comprising:
- a calcined, acidic, rare earth-treated crystalline zeolite impregnated with at least one ruthenium compound and at least one nickel compound subsequent to calcination.
A method for the preparation of a composition comprising:
- contacting a crystalline zeolite with an aqueous cation exchange solution comprising at least one rare earth compound and at least one ammonium compound;
- removing the zeolite from said solution and washing said zeolite with water to remove excess ions;
- calcining said zeolite;
- cooling said calcined zeolite;
- impregnating said calcined zeolite with a solution comprising at least one ruthenium compound and at least one nickel compound in a suitable solvent;
- and
- removing said solvent by evaporation.
