Zusammenfassung:PROBLEM TO BE SOLVED: To provide a method for efficiently manufacturing a zeolite shaped article having a high hardness and excellent crystal structure with satisfactory efficiency. SOLUTION: The zeolite shaped article has the following characteristics: (1) relative density ≥60%; (2) specific surface area ≥200 m2/g; (3) Vickers hardness ≥0.5 pa. The zeolite shaped article is manufactured by applying a heating pressurization treatment to a zeolite powder iunder the presence of water or aqueous alkali solution. COPYRIGHT: (C)2006,JPO&NCIPI
