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