5A Molecular Sieve Suppliers and Manufacturers

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. Attention To avoid damp and pre-adsorption of organic before running, or must to be reactivated.

Summary Molecular sieve is a kind of cubic crystal aluminosilicate compounds. Molecular sieve has the advantages of uniform porous structure, the diameter of the aperture size uniform, these holes to the adsorption of molecules smaller than the diameter of the cavity to the internal, and the polar molecules and unsaturated molecules has a preferential adsorption capacity, and are better able to different degrees, different saturation degree, molecular size and the boiling point of different molecules are separated, that is "screening" molecular, the so-called molecular sieve. Molecular sieve has the advantages of high adsorption capacity, high thermal stability, and so on, so that the molecular sieve is widely used.

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
