摘要
PURPOSE: A producing method of zeolite molecular body for producing oxygen is provided to secure the high sorption capacity by preventing the remaining of inert bonding agent ingredients. CONSTITUTION: A producing method of zeolite molecular body for producing oxygen comprises the following steps: adding a cellulosic compound and an organic vehicle into a mixture containing a colloidal silica aqueous solution and X-type zeolite powder, to obtain spherical agglomerate; incinerating the agglomerate at 500~700deg C: removing the cellulosic compound and the organic vehicle for obtaining the minute agglomerate; contacting the agglomerate with a mixture containing an alkaline aqueous solution and an aluminum hydroxide aqueous solution for transforming silica components into zeolite components; ion-exchanging the agglomerate by contacting with a solution containing lithium; heat processing the agglomerate at 400~600deg C; and activating the agglomerate after removing the moisture.
