 Molecular Sieve Desiccants A molecular sieve is the most effective option for removing water from liquids and gases. Though older products such as silica gel and alumina desiccants have traditionally been used for such purposes, molecular sieve desiccants can get the job done with purer results. The trick with mole sieve is the construction. These adsorbents are made with tiny and uniform pores, making them ideal adsorbents. In this way, molecular sieve desiccants work like any common sieve, only on a much more precise level. When a gas or liquid is passed through the mole sieve, smaller pieces are adsorbed while larger molecules pass through. Unlike other filters, the adsorbed substance is then trapped. Therefore, when water is used in the sieve, penetrating water molecules are caught and retained in the pores, leaving the remaining liquid substantially cleared of the water molecules. In all, a mole sieve adsorbs up to 22% of its own weight in water. More than that, these sieves are exceptionally versatile, with adsorption possible based on molecular size, molecular affinity for the sieve crystal surface, or even the shape of the molecule. For these reasons, molecular sieve desiccants can produce gases or liquids that are virtually water free. Molecular sieve can be regenerated by heating it to an optimal temp from 130°C to 250°C.
