An ion exchange method is provided for loading and uniformly distributing noble metals into a catalyst substrate comprising a zeolite to make a monofunctional, non-acidic reforming catalyst. The catalyst substrate is contacted with an aqueous loading solution comprising noble metal cations and non-noble metal cations. The loading solution is formulated such that the equivalents of non-noble metal cations remaining in the catalyst not ionically bonded to the zeolite when loading is complete is 1.2 to 6.0 times the equivalents of non-noble metal cations displaced from the zeolite when the noble metal cations ion exchange into the zeolite, and simultaneously the endpoint pH of the loading solution is between 10.0 and 11.5. The required 1.2 to 6.0 ratio is achieved when the ratio of moles of non-noble metal cations added to the loading solution to moles of noble metal added to the loading solution is between 1 and 10. The use of ion exchange method results in zeolite catalysts having reduced amounts of detrital material in the micropores of the zeolite.

A process for producing zeolite aggregates involves providing a formable paste composed of zeolite, a binder composed of an organic/metal oxide containing aluminum, a peptizing agent and water; forming the paste into an aggregate, preferably by extruding into an extrudate; curing the aggregate; hydro-thermally calcining the aggregate; and washing the hydro-thermally calcined aggregate with a washing medium, preferably followed by rinsing with a rinsing medium to remove residual washing medium from the aggregate. The washed and rinsed aggregate may then be permitted to equilibrate or is subjected to a drying procedure. Preferably, the washed and rinsed aggregate is again subjected to curing/hydro-thermal calcining. The resultant aggregates, such as extrudates, have an exterior surface with openings and interstitial spaces between particles of binder and zeolite which communicate by such openings between the exterior surface of the aggregate and micropores of the zeolite; the aggregates also exhibit characteristics of crush strength greater than about 0.9 pounds per millimeter and a loss by attrition of less than about 3.0%. Regenerable catalysts, such as reforming catalysts, based on such aggregate also exhibit a catalyst activity pass through to the zeolite bound in the aggregate of at least 70% of the initial catalyst activity of freshly prepared zeolite, as well as exhibiting more than about 70% of the reforming benzene yield that the reforming catalyst exhibited when similarly tested prior to being exposed to a hydrocarbon stream under specified reforming conditions of the catalyst activity test procedures.
