Abstract
An aromatic hydrocarbon is contacted under hydroalkylation conditions and in the presence of hydrogen with a composition comprising at least one platinum compound supported on a calcined, acidic, nickel and rare earth-treated crystalline zeolite.
Claims13
A composition comprising:
- at least one platinum compound supported on a calcined, acidic, nickel and rare earth-treated crystalline zeolite wherein the rare earth content of the calcined, acidic, nickel and rare earth-treated crystalline zeolite is within a range of from about 2 to about 25 percent by weight of the composition.
A method for the preparation of a composition comprising:
- contacting a crystalline zeolite with an aqueous cation exchange solution comprising rare earth, nickel, and ammonium compounds;
- removing the cation exchanged zeolite from said solution and washing said zeolite with water to remove excess ions;
- calcining said cation exchanged zeolite;
- cooling said calcined zeolite;
- impregnating said cation exchanged zeolite with a solution comprising at least one platinum compound in a suitable solvent;
- and
- removing said solvent by evaporation,
- wherein said cation exchanged zeolite is calcined and then cooled either before or after said platinum compound is impregnated on said zeolite wherein the rare earth content of the calcined, acidic, nickel and rare earth-treated crystalline zeolite is within a range of from about 2 to about 25 percent by weight of the composition.
