Abstract (en)

[origin: WO9912641A1] A dessicant comprises a solid, porous carrier of for example silica, alumina, carbon black, paper or the like with a hygroscopic material, in particular a hygroscopic salt such as a chloride, impregnated therein. The hygroscopic material is provided on the carrier in a homogeneous distribution of at least one monomolecular layer. The carrier has a surface area of approx. 200 - 350 m<2>/g and/or a pore volume of approx. 0.8 - 1.5 cm<3>/g and/or a pore diameter of approx. 150 - 250 ANGSTROM . This results in a desiccant having very good adsorption characteristics.
