Abstract
Methods for producing supported catalysts containing a transition metal and a bound zeolite base are disclosed. These methods employ a step of impregnating the bound zeolite base with a transition metal precursor in a solvent composition containing water and from about 5 wt. % to about 50 wt. % of a Cto Calcohol compound, a chlorine precursor, and a fluorine precursor. The resultant supported catalysts have improved catalyst activity and selectivity, as well as lower fouling rates in aromatization reactions.
