摘要： PURPOSE:To produce a formed article of type-A zeolite having large adsorption capacity without lowering the strength by calcining a formed article of sodium type-A zeolite crystal powder containing a binder and contacting the calcined product with a solution containing an exchangeable metal ion. CONSTITUTION:Powder of sodium type-A zeolite crystal is compounded with 5-15 pts.wt. (based on 100 pts.wt. of the powder) of a binder and the obtained mixture is formed and calcined. The calcined product is made to contact with a solution containing an exchangeable metal ion to effect the ion-exchange and obtain the objective formed article of type-A zeolite. The binder used in the above process is an inorganic binder (e.g. bentonite), an organic binder (e.g. methylcellulose), etc. The formed article of sodium type-A zeolite is preferably dried at a low temperature (100-200 deg.C) to prevent the mutual adhesion. The calcination is preferably carried out at a temperature as high as possible in a range giving no influence on the crystal structure of zeolite (e.g. at >=400 deg.C).
