Abstract

Macroporous desiccant based honeycomb matrix containing the macroporous desiccant synthesized 'in-situ', the desiccant having a differential water adsorption. Process for the 'in-situ' preparation of the macroporous desiccant based honeycomb matrix including the steps of soaking honeycomb substrate impregnated with water glass, in aqueous metal salt(s) solution or acid solution, or combination thereof, until such time that the hydrogel honeycomb matrix is obtained and thermally activating the hydrogel honeycomb matrix to produce macroporous desiccant based honeycomb matrix.
