ZEOLITE

(DEC IMPIANTI)

Molecular Sieves are mineral synthetic products (zeolites) with remarkable selective adsorption properties. Through the process of "activation", which consists in expelling the water from the crystalline structure, a highly active porous adsorbing material is obtained.

Molecular sieves, also known in the industry as "mol sieves", are synthetic zeolites or metal alumino silicates with a porous tridimensional crystallized network. "Molecular sieves" or "desiccants" (common word used only for the insulating glass market) are so called because of their property of screening molecules at the molecular scale. Molecular sieves differ from other adsorbents such as silica gel or activated alumina which have very wide pore distributions. Molecular sieves have regular pore sizes. Based on the pore size, they are called 3, 4, 5, or 10 Angstroms although the real pore opening is somewhat smaller to these values.
