Claims7
A composition consisting essentially of:
- at least one rhenium compound supported on a calcined, acidic nickel and rare earth metal-treated crystalline zeolite wherein the elemental rhenium content is within the range of 0.01 to about 1 percent by weight of the composition;
- wherein the elemental nickel content is within the range of about 0.01 to about 15 percent by weight of the composition;
- wherein the elemental rare earth content is within the range of about 2 to about 25 percent by weight of said composition;
- and wherein said zeolite is selected from the group consisting of type X, type L, and type Y zeolites.
