ABSTRACT:
A method is provided for obtaining crystalline dealuminized products by treating a slurry of a crystalline aluminosilicate zeolite in an aqueous solution of an ammonium or alkali metal salt which upon acidification yields an anion which complexes with aluminum by adding to said slurry a water-soluble acid having a first ionization constant greater than 10.sup.-2 at a rate such that a controlled amount of aluminum is removed from the zeolite to yield a resulting product from which at least about 10% and as much as about 85% of the initial aluminum has been removed while retaining more than 60% of the original crystallinity.
