Patent 7713513 was granted and assigned to Honeywell UOP on May, 2010 by the United States Patent and Trademark Office.
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:M1an+Al(1−x)ExSiy′Oz″and are prepared by treatments such as acid extraction and AFS treatments.
