Zeolite 13X is the most commonly used adsorbent in the air separation for oxygen production. Zeolites are aluminosilicate crystallines of alkaline or earth alkaline elements such as sodium, potassium and calcium.Sep 1, 2017
What is a type zeolite?
Type A zeolites are synthetic, hydrous, alkali aluminosilicates, with exceptionally advantageous structural channels and cavities1. The cubic framework structure is commonly used as a selective sorbent for drying gases and solvents.Jul 16, 2019
What is 4A Zeolite?
Doucil®4A zeolite. DOUCIL® 4A is a zeolite of the first generation optimized for use as a builder, liquid carrier and/or processing aid in laundry detergent products, helping manufacturers to produce detergents with excellent physical properties and cleaning performance.
What is molecular sieve method?
A molecular sieve is a material with pores (very small holes) of uniform size. ... Some molecular sieves are used in size-exclusion chromatography, a separation technique that sorts molecules based on their size. Other molecular sieves are used as desiccants (some examples include activated charcoal and silica gel).
What is molecular sieve filtration?
Molecular sieves are in the family of desiccants, also known as adsorbents, used for hydrocarbon drying, described as the removal of dissolved water from hydrocarbon gases and liquids. ... High-efficiency filtration and separation is key to achieving this reliability and targeted desiccant bed campaign length.

How is molecular sieve made?
Molecular sieve starts out as powder. The powder is then combined with a binding material. This allows the powder to be rolled into beads. ... This exchanges about half of the sodium ions in the structure with potassium ions, which changes the effective diameter of the pore openings and creates the 3A molecular sieve.May 15, 2017
What is molecular sieve effect?
molecular sieve effect (rus. эффект, молекулярно-ситовой) — the effect that includes various availability of the inner space of porous materials for molecules different in size.
What is molecular sieve activation powder?
4A molecular sieve activation powder: An additive or aggregate used in paints, paints, resins, and certain adhesive agents to reduce moisture.Jul 13, 2017
What is 5A molecular sieve?
Molecular sieve 5A is a calcium form of alkali alumina silicate with an effective pore diameter of 5A°. It will adsorb all the molecules with a kinetic diameter of fewer than 5 angstroms and exclude higher than that. ... It offers a tremendously effective adsorbent with a contact surface and large porosity.
What is 5A zeolite?
Molecular sieve 5A, also called zeolite 5A or zeolith 5A, is one type of aluminosilicate crystal with average pores measuring of 5 angstrom (0.5 nm). Molecular with kinetic diameter larger than 5 angstrom will be adsorbed by zeolite 5A, otherwise be excluded.
What is 4A molecular sieve?
4A molecular sieve means the molecules with the pore size of 4A0 or 4 angstroms are used for the adsorbing process. It simply signifies that molecules with the pores size larger than 4a cannot be used for adsorption. ... Such type of molecular sieve is perfect to remove the moisture from liquids and gases.
