A family of crystalline aluminosilicate zeolites designated UZM-8HS and derived from UZM-8 have been synthesized. The aluminum content of the UZM-8HS is lower than that of the starting UZM-8 thus changing its ion exchange capacity and acidity. These UZM-8HS are represented by the empirical formula: M1.sub.a.sup.n+Al.sub.(1-x)E.sub.xSi.sub.y'O.sub.z'' and are prepared by treatments such as acid extraction and AFS treatments.
