Vendeur: grhman2015 (64) 100%, Lieu où se trouve: Huntingdon, Cambridgeshire, Lieu de livraison: Europe, Numéro de l'objet: 183685942532 Molecular Sieves are synthetic crystalline zeolites in which the atoms are arranged in a definite pattern. Internally, the structure has many cavities inter-connected by smaller pores of a uniform size. These pores are only able to accept and pass to the cavities molecules of the same and smaller size, hence the name molecular sieve. The water vapour adsorption characteristics are very different from those of silica gel. Molecular sieves can adsorb up to approximately 20% by weight of water before the relative humidity of the surrounding air increases significantly. Any further increase causes a large rise in relative humidity. Molecular Sieves are available in three primary generic forms, 3A, 4A, 5A. Each form has its own specific properties and applications, and all retain a polar preference for adsorption of water. • 3A is the preferred Molecular Sieves adsorbent for the commercial dehydration of unsaturated hydrocarbon streams. • 4A is the preferred Molecular Sieves adsorbent for the static dehydration in a closed gas or liquid drying system. • 5A is the preferred Molecular Sieves adsorbent for the separation of normal paraffin's from hydrocarbons.
