3 Angstrom Molecular Sieve Adsorbent High Anti - Pollution Capacity For Methane Gas
Molecular Sieve Beads 3A Adsorbent For Methane Gas 2.0-3.0 mm; 3.0-5.0 mm; 4.0-6.0 mm
Products Introduction
3A molecular sieve has a pore size of 3A or 3 angstrom. Any molecule larger than 3A will not be able to be adsorbed. Mole Sieve is an alkali metal alumino-silicate, the potassium form of the type A crystal structure. 3 Angstrom is created when part of the sodium ions of the 4 Angstrom sieve are replaced by potassium ions.

Storage
The molecular sieve shall be stored at room temperature, in which the relative humidity does not exceed 90%, and be not exposed to air, and prevented against water, acids and alkalizes.
Attention
1. The product cannot be exposed in the open air and should be stored in dry condition with the air-proof package.
2. The product should be regenerated after a certain period of adsorption. The appropriate regenerated temperature would be better below 350°C.
