Introduction
Chemxin 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). Chemxin 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.
Regeneration
Chemxin 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 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 process
Size
4a - 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.

Molecular Sieve 3A/5A/13X/13X-APG/13X-HP/Li-X/CMS
Molecular Sieve are so named because there are uniform pores inside the particles of molecular sieves, which can separate molecules of different sizes according to the size of the pores.
Zhongci, as a professional production factory for more than 20 years, produces many types of zeolite molecular sieve adsorbents.

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.

Molecular sieve is a kind of synthetic silicoaluminate with microporous cubic lattice.depending on the size of the pores inside the crystal,the molecules of different substances are adsorbed or repelled,and are therefore called "molecular sieve".substances whose molecular diameter is smaller than the pore diameter of the molecular sieve crystal can enter the molecular sieve crystal and be adsorbed.

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.
