本発明は含水粉粒体及びその製造方法に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a water-containing powder and a method for producing the same.
従来、有機系及び無機系の粉粒体に水分を添加する場合
、粉粒体に水を添加混合することが一般的に行われてい
る。しかしながら、このような水分添加方法では、粉粒
体に添加し得る水分量は少なく、せいぜい粉粒体に対し
２０〜３０重量％であり。Conventionally, when adding water to organic or inorganic powder or granules, water is generally added and mixed with the powder or granules. However, in such a water addition method, the amount of water that can be added to the powder or granule is small, at most 20 to 30% by weight based on the powder or granule.
それ以上の水分を加えると、水分が粉粒体中に吸収され

体は１粒子同志がその付着水のために付着結合し、塊状
物を作ったり等して粒子流動性が著しく損われ、もはや
粉粒体としての取扱いの著しく困難なものになる。If more water is added, the water will not be absorbed into the powder or granule and will adhere to the particle surface of the powder or granule, wetting the surface of the powder or granule. In the case of granules, particles adhere to each other due to adhering water, forming lumps, etc., and the fluidity of the particles is significantly impaired, making it extremely difficult to handle them as powder or granules.

として利用される。An example of adding water to a powder or granule is adding water to an alkaline substance such as calcium hydroxide or magnesium hydroxide. Such alkaline substances to which moisture has been added are used as acid gas absorbents such as carbon dioxide gas, sulfur dioxide gas, hydrogen chloride gas, organic acid gases, etc. In this case,
The presence of moisture promotes the reaction between the alkaline substance and the acidic gas, and the greater the amount of moisture, the more the reaction between the two is accelerated. In addition, there are examples in which water is added to porous fillers such as zeolite, keraatomaceous earth, silica, alumina, magnesia, calcia, and activated carbon. Such a water-added filler is suitable for gas-isomer reactions in which the reaction is promoted in the presence of water. It is used as a moisture source in reactions such as those between copper chloride and carbon monoxide.

場合、前記したように、従来の技術では、粉粒体に添加
し得る水分量には制約があった。In the solid-gas reaction described above, by increasing the water content of the water-containing powder or granules, the solid-gas reaction can be promoted, and the composition volume of the entire reaction system can be made compact. However, in this case, as described above, in the conventional technology, there are restrictions on the amount of water that can be added to the powder or granular material.
