Abstract
A family of crystalline aluminosilicate zeolites designated UZM-5HS and derived from UZM-5 have been synthesized. The aluminum content of the UZM-5HS is lower than that of the starting UZM-5 thus changing its ion exchange capacity and acidity. These UZM-5HS are represented by the empirical formula:M1an+Al(1−x)ExSiy′Oz″and are prepared by treatments such as acid extraction and AFS treatments.
