Descrizione

Descrizione generale

Molecular sieves are crystalline, synthetic zeolites. Their crystal gratings are similar to a cage with numerous hollow spaces. The cavities are accessible from all sides by pores of exactly defined dimensions. Molecular sieves can be generally used in desiccators and drying tubes; for keeping absolute solvents dry; for drying gases or solvents in drying columns.

Applicazioni

Molecular Sieve 13X is a highly porous sodium form of zeolite X that is widely used in the purification of air before liquefaction, natural gas purification, separation of substances, and drying. It is also suitable for the adsorption of large molecules such as aromatics, branched-chain hydrocarbons, and organosulfur compounds. Molecular Sieve 13X has a greater ability to accept molecules because of its higher SiO₂/Al₂O₅ ratio. Therefore, 13X also finds the application in the removal of phenolic pollutants.
