In order to improve the gas permeability and increase the processing efficiency, it is not preferable for the material to be tightly packed.Therefore, the gas permeable material has a configuration having many holes of a certain size. Small ones are used. At this time, if the composition for adsorption treatment has a small particle size, there is a problem in that the composition may fall from such a gas passage hole, and the commercial value may be lost, or sufficient adsorption performance may not be exhibited.

It must be in the range of 1.3-8% by weight. If the amount of the binder is less than 1.3% by weight, the granules will be crushed by a slight force even if granulated, and the meaning of granulation is lost. When the amount of the binder exceeds 8% by weight, the adsorptive compound and the water-absorbing substance are concealed by the binder portion, so that the number of sites for the adsorption treatment is reduced, and as a result, the adsorption performance is inferior. In addition, when a water-soluble polymer is used as a binder and an aqueous solution of an adsorptive compound is added to perform a granulation operation, when the water-soluble polymer exceeds 8% by weight, the viscosity of the system increases and the system becomes tacky, It is not preferable because granulation work becomes difficult. More preferably, the upper limit of the amount of the binder is 5% by weight, more preferably 3% by weight, based on the adsorptive compound.

In addition, a typical example of the adsorptive compound used in the present invention is a phenolic compound, and since there are many water-soluble compounds, a polymer dissolved in water and the adsorptive compound are mixed with a water-absorbing substance to form granules. By doing so, a granular material can be easily obtained. As the water-soluble polymer,
There are polyacrylic acid, polyvinyl alcohol, carboxymethyl cellulose, and the like, but polyvinyl alcohol is most preferable because the strength of the granular material is excellent even with a small amount of use. If the wettability with the water-absorbing substance is poor, granulation may be performed by adding a small amount of a surfactant.

It is used as a place for a chemical reaction between the adsorptive compound and the component to be adsorbed in the presence of moisture. Since the water absorption absorbs the moisture in the air, the reaction can proceed efficiently without externally supplementing the moisture serving as the reaction medium.

Zeolites can be classified into Na type and H type (proton type) depending on the ion type, but from the viewpoint of high reactivity with a carbonyl group-containing compound, H type zeolites are preferred. Also, as described below, when a weakly acidic substance or a weakly basic substance is used in combination with the adsorptive compound, the acid or alkali generated from these weakly acidic or weakly basic substances when absorbing moisture is used. There is a concern that acid and alkali corrosion of the adsorption treatment device and auxiliary equipment may occur.

も同様に有効に発揮される。Among the above-mentioned adsorbent compounds, resorcin belonging to polyhydric phenol is very preferably used as an adsorbent compound since it exhibits extremely excellent reactivity with carbonyl group-containing compounds. Especially with resorcinol,
When a weakly acidic substance such as oxalic acid or a weakly basic substance such as sodium carbonate is used in combination, the effect of capturing aldehydes and the like is further enhanced, and a more excellent adsorption treatment effect is exhibited. This is thought to be because the weakly acidic substance or the weakly basic substance acts as a catalyst for the reaction between resorcinol and formaldehyde, and such an effect is obtained by using a monohydric phenol or polyhydric phenol other than resorcinol as the adsorbing compound. In this case, it is similarly effective.

If the adsorptive compound is solid, it is dissolved in an appropriate solvent such as water or methanol, and What is necessary is just to granulate by the granulation method used. If heat treatment is performed after granulation, the solvent can be removed. Since water serves as a reaction medium, water may remain in the granular material. Even if no water remains, it is not necessary to replenish the water-absorbing substance because it is supplemented by absorbing moisture in the air, but it exhibits a high level of adsorption treatment activity from the beginning of the adsorption treatment. It is desirable that an appropriate amount of water be absorbed by the water-absorbing substance from the beginning.

If the amount is less than 0.1% by weight, the adsorbing performance is not sufficiently exhibited, and even if the amount exceeds 50% by weight, no further improvement in the adsorbing performance is observed. Also, when the amount of the adsorptive compound was increased, there was also a tendency that granulation properties were deteriorated.
