3A Molecular Sieve

3A Molecular Sieve

Molecular Sieve type 3A is an alkali metal alumino-silicate; it is the potassium form of the type A crystal structure. Type 3A has an effective pore opening of about 3 angstroms (0.3nm). This is large enough to allow in moisture, but excludes molecules such as unsaturated hydrocarbons which can potentially form polymers; and this maximises lifetime when dehydrating such molecules. Molecular sieve Type 3A 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 3A molecular sieve, a temperature of 200-230°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...







4A Type Molecular Sieve

4A Type Molecular Sieve

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). 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. 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 3A molecular sieve, a temperature of 200-230°C is required. A properly regenerated molecular sieve can give moisture...






5A Type Molecular Sieve

5A Type Molecular Sieve

5A molecular sieve pore size for 5A, can adsorption is less than the diameter of any molecule, is mainly used in heterogeneous hydrocarbon separation, pressure swing adsorption, adsorption separation and water and carbon dioxide, based on the industrial application characteristics of 5A molecular sieve, we in the production of 5A molecular sieve choose high adsorption, adsorption speed, especially suitable for the pressure swing adsorption, can adapt to all kinds of size of oxygen, hydrogen, carbon dioxide and other gases pressure swing adsorption device, is the high-quality goods in the industry pressure swing adsorption (PSA). 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...






13X Type Molecular Sieve

13X Type Molecular Sieve

Molecular Sieve 13X is the sodium form of the type X crystal and has a much larger pore opening than the type A crystals. It will adsorb molecules with a kinetic diameter of less than 9 Angstrom (0.9 nm) and exclude those larger. It also has the highest theoretical capacity of the common adsorbents and very good mass transfer rates. It can remove impurities too large to fit into a type A crystal and is commonly used to separate nitrogen from oxygen. Removal of CO2 and moisture from air (air pre-purification) and other gases. Separation of enriched oxygen from air. Removal of mercaptans and hydrogen sulphide from natural gas. Removal of mercaptans and hydrpogen sulphide from hydrocarbon liquid streams (LPG, butane, propane etc.) Catalyst protection, removal of oxygenates...






13X APG Molecular Sieve

13X APG Molecular Sieve

Type 13X APG molecular sieve is specially designed to co-absorb CO2 and H2O for air cryo-separation industry. It has largeer capacity and faster adsorption speed for removal of CO2 and H2O to prevent the bed gelation, it is suitable for any air cryo-separation plants of any size and any types in the world. Attention: To avoid damp and pre-adsorption of organic before running, or must to be reactivated.
