Title:
水蒸気吸着材及びその製造方法
Document Type and Number:
Japanese Patent JP6894094
Kind Code:
B2
Abstract:
To provide a steam absorbent consisting of a granulated body obtained by adding a hygroscopic salt to a powder consisting of amorphous aluminum silicate, having not only high absorption performance in a middle to high temperature range, but also excellent detachment performance capable of recycling at a temperature of about 100°C, having no generation of decomposition of the granulated body in a repeated absorption and detachment process, and does not allow the hygroscopic salt to get out in the absorption and detachment process of steam.SOLUTION: There is provided a steam absorbent consisting of a granulated body containing at least an amorphous aluminum silicate power and a hygroscopic salt, and the hygroscopic salt is contained at an amount so that steam absorption amount at a temperature of 25°C and relative humidity of 95% under air pressure of the granulated body is pore volume by total of nano pores, meso pores and macro pores with pore diameter of 1 nm to 10 μm obtained by the granulated body or less.SELECTED DRAWING: Figure 1
