Product Description (ISO 9001:2015) Manufacturer China Molecular Sieve 4AMolecular 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). XINGFENG 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.Typical Chemical Formula Na2O Al2O3 2.0SiO2 4.5H2O SiO2: Al2O3 ≈2 Technical ParameterItemUnitTechnical dataShape PelletSphereDiametermm1.5-1.73.0-3.31.7-2.53.0-5.0Size ratio up to grade%≥98≥98≥98≥98Bulk densityg/ml≥0.66≥0.66≥0.70≥0.70Wear ratio%≤0.20≤0.40≤0.20≤0.20Crushing strengthN≥30/cm≥45/cm≥30/p≥70/pStatic water adsorption%≥21≥21≥21≥21Static methanol adsorption%≥15≥15≥15≥15Water content, as shipped%≤1.5≤1.5≤1.5≤1.Application Drying and removing of CO2 from natural gas, LPG, air, inert and athmospheric gases, etc.Removal of hydrocarbons, ammonia and methanol from gas streams (ammonia syn gas treating)Special types are used in the air break units of buses, trucks and locomotives.Packed in small bags, it may be used simply as a packaging desiccant.RegenerationMolecular 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 processSize4A - 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 1.6", 3.2".Attention To avoid damp and pre-adsorption of organic before running, or must to be reactivated.Packing and Shipping:Package TypeContainer Load CapacityDelivery timeQuality Insurance20 GP40 GPSteel drum, 150kg/drum12000 kg24000 kgWithin 7-10 daysChinese National Standard; Offer quality assurance as request.Paper drum, 25kg/drum9000 kg18000 kgPaper box, 25kg/box13500 kg27000 kg
