    摘要: 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.

    摘要: Provided is a process for polymerization and copolymerization of ethylene, specifically comprising carrying out polymerization or copolymerization ethylene in the presence of (a) a solid complex titanium catalyst which is produced by the process comprising: (i) preparing a magnesium compound solution by contacting a halogenated magnesium compound and an alcohol for allowing a reaction; (ii) reacting the resulted magnesium compound solution with an ester compound having at least one hydroxyl group and a silicon compound having at least one alkoxy group; (iii) reacting the resulted solution with a mixture of a titanium compound and a silicon compound to obtain a solid titanium catalyst component; (iv) washing the resulted solid titanium catalyst component with a halogenated saturated hydrocarbon compound; and (v) further reacting the washed solid titanium catalyst component with a titanium compound to obtain a solid complex titanium catalyst, and (b) an organometallic compound from Group II or III of Periodic table of elements. According to the present invention, it is possible to provide a process for polymerization or copolymerization of ethylene in which the catalyst activity is improved and a polymer of high bulk density is provided, with the use of a catalyst prepared by a simple process.
