Columns, grains, honeycombs, and other shapes are used for various applications. However, the zeolite powder itself does not exhibit plasticity, and even if this is kneaded with water, a plastic suitable for molding cannot be obtained. So, conventionally,
In order to plastically mold and bake the zeolite powder, natural clay, bentonite, kaolin, silica, alumina, and other inorganic binders are added, followed by baking after molding. However, if an inorganic binder is added, zeolite characteristics such as adsorption ability per unit weight and catalytic activity per unit weight of the molded body are lower than that of the zeolite powder itself due to the inorganic substances remaining in the molded body even after firing.

Ammonium polycarboxylate is known as an aqueous dispersant for inorganic powder, and by adding it, the wettability of zeolite is improved and a kneaded composition in which zeolite is well dispersed is obtained. It is considered that the plasticity of the product is improved.

り、好ましくない。The polycarboxylic acids include, for example, aliphatic, alicyclic and aromatic hydrocarbon polycarboxylic acids and unsaturated carboxylic acids such as acrylic acid, methacrylic acid, maleic acid and itaconic acid. Among them, a polymer of acrylic acid is preferable in consideration of performance as a dispersant, availability, and the like. Therefore, in the present invention, ammonium polyacrylate is preferably used as ammonium polycarboxylate.

トに所望のカチオン種を導入することも可能である。As a method for forming the zeolite composition for molding as described above, extrusion molding, tumbling granulation, and the like can be considered. Usually, a method of molding by kneading and then extruding is employed. . Furthermore, in the present invention, a green molded article obtained by molding is fired to obtain a zeolite molded article. The firing temperature is usually from 300 to 1000C, preferably from 500 to 700C. If the firing temperature is too low, it is not possible to completely remove ammonium polycarboxylate and other organic auxiliaries used for molding. On the other hand, if the firing temperature is too high, the crystal structure of the zeolite will be broken, and the properties of the zeolite will be lost. The firing method can be performed by filling in a sheath and firing in a muffle furnace, a tunnel furnace, or the like.However, considering the control of heat generation during firing, a method of firing while flowing gas through a green molded product is preferable. . The shape of the zeolite molded body may be any shape, and examples thereof include a columnar shape, a ring shape, a spherical shape, a sheet shape, and a honeycomb shape. If necessary, it is also possible to ion-exchange the zeolite compact to introduce a desired cationic species into the zeolite.

The obtained kneading composition was extruded using a die having a hole diameter of 3 mm, and as a result, the molding was successfully performed. The molded product was dried at 120 ° C. for 24 hours, and the dried product was sized to a length of 5 mm and calcined at 550 ° C. for 5 hours to obtain a molded product. The crushing strength of the molded body was measured using an autograph (AGS-500B manufactured by Shimadzu Corporation). The result was an average strength of 0.3 kg / piece.

The obtained kneaded composition was extruded using a die having a hole diameter of 3 mm. As a result, the load of the extruder increased abnormally, and the molded product did not come out of the die.
