The Molecular Sieve inside the Oxygen Concentrator towers (sieve beds) will need to be replaced if there is a white powder visible in the machine or if there are high air pressure levels. Contamination of the Sieve can be caused by moisture in the air and the filters prior to the Oxygen Concentrator not functioning. Specifications
Molecular Sieve Molecular sieve is high performance adsorbent with excellent kinetic gas adsorption and separation capacity. Moleular sieve is widely used in various industries such as air separation, oxygen generator, hydrogen purification, natural gas dehydration, ethanol dehydration, ethylene dehydration, propylene dehydration, refrigerant dehydration, air break system etc.

Apr 10, 2019· Zeolite Molecular Sieve Market was valued US$ 4.81 Bn in 2017 and is estimated to reach US$ 6.72 Bn by 2026 at a CAGR of 4.27 % during the forecast. Zeolite molecular sieve is …
Zeolite molecular sieves are used in industrial applications since more than 60 years, mainly as highly efficient adsorbents for separation processes in gas or liquid phase. Zeolite molecular sieves may be applied in powder form, preferably in static applications, but to a much larger extent as shaped material in both static and dynamic (flowing media) applications.
Computational and Experimental Approach to the Role of Structure-Directing Agents in the Synthesis of Zeolites: The Case of Cyclohexyl Alkyl Pyrrolidinium Salts in the Synthesis of β, EU-1, ZSM-11, and ZSM-12 Zeolites
Molecular sieve is also know as a zeolite. A zeolite is a conformation of hydrated aluminosilicates of sodium, potassium, calcium, or other cations. Zeolites can be dehydrated and rehydrated, making them useful in drying applications.

Mar 22, 2019· Zeolites can exchange other positively charged ions for the metal ions originally trapped inside them (technically this is known as cation exchange) and, as Cronstedt found over 250 years ago, they can gain or lose their water molecules very easily too (this is called reversible dehydration).
3A Molecular Sieve is a synthetic zeolite. The pore size is 3 Ångstroms in diameter and has undergone an ion exchange, replacing a sodium (Na) ion with a potassium (K) ion to offer a smaller pore size.
Molecular sieve: Molecular sieve, a porous solid, usually a synthetic or a natural zeolite, that separates particles of molecular dimension. Zeolites are hydrated metal aluminosilicate compounds with well-defined crystalline structures. The silicate and aluminate groupings form three-dimensional crystal lattices
