Molecular Sieves
Specific Application：
Deep drying of air, natural gas, alkaline, refrigerants and other gases and liquids; Static drying of pharmaceutical packaging, electronic components and perishable objects; The preparation and purification of air etc.
Xintao Molecular Sieve type 4A is an alkali alumina silicate; it is the sodium form of the Type A crystal structure. 4A molecular sieve has an effective pore opening of about 4 angstroms (0.4nm). Guangdong Xintao type 4A molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger. Such adsorb-able molecules include simple gas molecules such as oxygen, nitrogen, carbon dioxide and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excludeRegeneration:Guangdong Xintao molecular sieve Type 4A can be regenerated by either heating in the case of thermal swing processes; or by lowering the pressure in the case of pressure swing processes. To remove moisture from a 4A molecular sieve, a temperature of 250-280°C is required. A properly regenerated molecular sieve can give moisture dew points below -60°C. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process Size: pellet 2-3 mm.
