Introduction:
Molecular sieves are highly porous crystalline metal-alumino silicates. It has a uniform pore diameter and high specific surface area and other excellent features. It only adsorb those molecules smaller than the molecular sieve aperture, and has a rather strong water absorption capacity, even at a higher temperature, larger space velocity or large water content condition. It is widely used in chemical, petrochemical, natural gas and other industries.
Molecular sieve absorbs 18% to 22% of its own weight and can hold moisture to temperatures well past 450°F (230°C). Because of its high affinity for moisture, molecular sieve is able to bring the relative humidity in packages down as low as 10% RH.
