Abstract
The present invention provides a method for preparing a BaX type zeolite granules comprising: adding a carbohydrate-based molding promoter to NaX type zeolite powder and thereto subsequently spraying and blending alumina sol and silica sol to form granules of the mixture; heating the formed granules to convert the alumina and silica component to aluminosilica so as to generate pores inside the formed granules; hydrothermally treating the resulted granules in a sodium hydroxide aqueous solution under the conditions for zeolite synthesis, thereby converting a portion of the aluminosilica to zeolite; and carrying out ion-exchanging by Ba ions. The present invention also provides BaX type zeolite granules which have excellent strength and can be suitably used as an adsorbent in simulated moving bed (SMB) application.
