Abstract:
1. A composite adsorbent material, comprising: a porous host material of activated carbon impregnated with silica-gel and calcium chloride, the composite adsorbent material providing adsorption in adsorption cooling systems or dehumidification systems, wherein the composite adsorbent material comprises the activated carbon, as a host material, impregnated with the silica-gel, followed by further impregnating the silica-gel coated host material with the calcium chloride, thereby rendering a structure of the obtained silica activated carbon impregnated with the calcium chloride, the impregnation of the activated carbon with silica-gel increasing performance of adsorption capacity at a lower pressure region and the subsequent impregnation of the host material with the calcium chloride subsequent to impregnation with silica-gel providing increased adsorption capacity toward water vapor, with the impregnating the calcium chloride into the silica-gel helping the calcium chloride to maintain its solid structure which would otherwise result from the calcium chloride forming a solution with water vapor, the subsequent impregnation of the host material with the calcium chloride subsequent to impregnation with silica-gel further increasing the overall performance of adsorption capacity at a wider pressure range.
