The pore size of 3A molecular sieve is 3 A . It does not adsorb any molecular larger than 3 Å. It is an alkali metal alumina-silicate, the potassium form of the typ A crystal structure. 3 Angstrom, is obtained when part of the sodium ions of the 4 Angstrom sieve are replaced by potassium ions. Will adsorb, in sequence of adsorption rate, helium, neon, nitrogen and water.

According to the industrial application specialties, we endue our products with the characters of higher adsorption speed, stronger crushing and anti-contaminative resistance, more cyclic times and longer work-span. All these advantage have made it come to be the most essential and necessary desiccant in the fields of the deep drying, refinery, polymerization for cracked gases, ethylene, propylene and any other non-acidic gases or liquids in petroleum and chemical industrials.

Most of the industries require 100% water-free Ethanol. The finally manufactured alcohol is a rectified spirit with almost 94.6% alcohol and the remaining percentage is water. It is very difficult to remove the amount of water in alcohol using any straightforward and simple distillation process. Therefore, a special dehydration process needs to be carried out using latest technology to manufacture the absolute alcohol. In the case of ethanol, water is extracted by making it dehydrated with the help of adsorbent structure of molecular sieve 3A.

Molecular Sieve type 4A (Angstrom) is an alkali alumina silicate, obtained through synthesis of type A zeolite in sodic form. 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). Galaxychem type 4A molecular sieve will absorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger.

Formula: Na2O·Al2O3·2SiO2·4.5H2O

Silica-alumina Ratio: SiO2/ Al2O3≈2

Aperture: 4A

Molecular Sieve type 5A is an alkali alumina silicate; it is the calcium form of the Type A crystal structure. The pore size of 5A molecular sieve is about 5A . It can absorb all kind of molecular smaller than this size, zeolite desiccant molecular sieve 5a is mainly used in separation of the normal and isomerous alkane; pressure swing absorption (PSA) for gases; co-absorption of moisture and carbon dioxide.

Molecular Sieve 13X is the sodium form of the type X crystal and has a much larger pore opening than the type A crystals. The pore size 13X molecular sieve is about 10 A. It can absorb any molecular smaller than 10 A, mainly used as catalyze carrier, co-absorption of CO2 and H2O, H2O and H2S, as desiccant for medical and air compressor system, and can also be adjusted to fit other various applications.

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.
