ABSTRACT:
This invention relates to zeolites of the faujasite type generally referred to as X or Y zeolites which contain both aluminum and NH.sub.4 in exchange position and catalysts employing the same.
The zeolite of our invention is derived from the sodium form of the zeolite by first exchanging the sodium form with an aluminum ion to replace a substantial portion of the sodium and further reducing the sodium content of the zeolite by exchange with an ammonium ion.
