4A Molecular Sieve, is an alkali alumina silicate. It is the sodium form of the type A crystal structure. It has an effective pore opening of about 4 angstroms(0.4nm). It will adsorb most molecules with a kinetic diameter of less than 4 angstroms and exclude those larger.

Xintao 4A Molecular Sieve, the pore size distribution is very uniform, has very good adsorption properties and good oil adhesion, and has a certain buffer alkalinity effect. It is non-toxic, safe and reliable to human body, and has no adverse effects on ecosystem.


Activated alumina desiccant is a porous form of granular alumina with high surface area for efficient adsorption of liquids and gases.

When the gas passes through alumina, the water in the gas will be adsorbed by activated alumina, so activated alumina balls are widely used in the deep drying of cracked gas, ethylene and propylene, hydrogen production, oil and gas separation, air separation, and air drying of electronic instruments , hydrogen peroxide dehydration, can also be used in the absorption of pollutants, such as h2s, so2, HF and paraffin in the exhaust gas.
