A molecular sieve is a material with tiny, uniform pores that is used to adsorb gases and liquids. Unlike common filters, the molecular sieve operates on a molecular level. It only could adsorb molecules which are small enough to pass through the pores, such as water molecules. Because of this, the molecular sieve is usually used as a desiccant, which can adsorb water up to 22% of its own weight. Molecular sieves often consist of aluminosilicate minerals, clays, zeolites, active carbons, synthetic compounds, etc. that have pores which small molecules can pass through. Usually, a 4 to 8 mesh sieve is ideal for gas phase applications, and a 8 to 12 mesh sieve is perfect for liquid phase applications. The powder forms of the 3A, 4A, 5A and 13X sieves are used in specialized applications. Xiangrun is an experienced molecular sieve manufacturer in China. To ensure our customers could find the product they are looking for, we offer four types of molecular sieves, which are listed below carton packing, drum packing

Zeoli is a magical aluminosilicate mineral and contains potassium, calcium and sodium as exchangeable elements. There are different types of zeolites, among which clinoptilolite zeolite can be used as a molecular sieve in the agricultural industry due to its ion exchange and porous structure.
Introduction Chemxin molecular sieve type 5a is an alkali alumino silicate; it is the calcium form of the type a crystal structure. Type 5a has an effective pore opening of 5 angstroms (0.5 nm). It will adsorb molecules with a kinetic diameter of less than 5 angstrom and exclude those larger. It is especially suitable for psa adsorber applications where it may be used for the separation of normal- and iso- paraffins (c4 to c6 species), in psa hydrogen purification and in oxygen concentrators. Regeneration Chemxin molecular sieve type 5a 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 5a molecular sieve, a temperature of 250-300°c is required. A properly regenerated molecular sieve can give moisture dew points below -100°c, or mercaptan or co2 levels below 2 ppm. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process. Size 5a - zeolites are available in beads of 1-2 mm(10x18 mesh), 2-3 mm(8x12 mesh), 2.5-5 mm(4x8 mesh) and as powder, and in pellet 1.6mm, 3.2mm.
Introduction Chemxin molecular sieve type 4a is an alkali alumino 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). Chemxin type 4a molecular sieve will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger. Such adsorbable molecules include simple gas molecules such as oxygen, nitrogen, carbon dioxyde and straight chain hydrocarbons. Branched chain hydrocarbons and aromatics are excluded. Regeneration Chemxin 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 -100°c. The outlet concentrations on a pressure swing process will depend on the gas present, and on the conditions of the process Size 4a - zeolites are available in beads of 1-2 mm(10x18 mesh), 2-3 mm(8x12 mesh), 2.5-5 mm(4x8 mesh) and as powder, and in pellet 1.6mm, 3.2mm. Attention To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
