ABSTRACT:
The instant invention comprises a process for increasing the framework aluminum content of a framework aluminum deficient zeolite containing non-framework aluminum by contacting said zeolite with an aqueous basic solution at a temperature greater than about 25.degree. C. Preferably the aqueous solution comprises ammonium and/or alkali metal hydroxides dissolved in water and the contact temperature ranges between about 60.degree. C. and about 90.degree. C. The instant invention also relates to the zeolites thus prepared by the instant process.
