ABSTRACT:
The catalytic properties of a metal-containing shape selective crystalline silicate zeolite are significantly improved by converting said metal to an intermetallic compound. Thus, for example, zeolite beta containing the intermetallic component platinum zeolite demonstrates improved catalytic properties for dewaxing a hydrocarbon feedstock compared to zeolite beta containing platinum metal alone.
