Abstract: PURPOSE: A BaX type zeolite shaped body and a manufacturing method of the same are provided to improve the apparent density and the mechanical strength of the BaX type zeolite shaped body. CONSTITUTION: A manufacturing method of a BaX type zeolite shaped body includes the following steps: a carbohydrate-based forming promoter is introduced into NaX type zeolite powder, and alumina sol and silica sol are successively sprayed and mixed with the zeolite powder and the promoter; the resultant product is formed in the shape of granules; the granules are classified to obtain granules of 0.24-1.20mm sizes; the granules of the pre-determined sizes are dried and plasticized to remove the carbohydrate-based forming promoter, and moisture and crystalline water of a binding agent are controlled to convert the alumina and the silica into aluminosilica to form pores; the resultant product is hydrothermal reacted to be separated and washed; the resultant product is treated with a barium ion aqueous solution to be ion exchanged, a washing and drying operation are followed; the resultant product is thermally treated at 250 to 650 deg C to remove crystalline water from zeolite.
