High Affinity Adsorbent 3A Molecular Sieve Desiccant For H2O NH3 H2S CO2 Adsorbing Producing
Product Description of 3A Molecular Sieve Desiccant
Selective Adsorption Based on Molecular Polarity, Unsaturation and Polarizability
Molecular sieves have a high affinity for polar molecules and unsaturated molecules; among non-polar molecules, they have a higher selective adsorption advantage for molecules with a high polarizability. In addition, the lower the boiling point of the molecule, the less easily adsorbed by the molecular sieve.
Molecular sieves have a high affinity for H2O, NH3, H2S, CO2 and other polymer polarities, especially for water, at low partial pressure (even below 133 Pa) or low concentration, high temperature (even above 100 ℃) and so on. It still has high adsorption capacity under severe conditions.
Molecular sieve is the only high-temperature adsorbent available. At 100 ℃ and 1.3 % relative humidity, the molecular sieve can absorb 15% by weight of water. So at higher temperatures, molecular sieve can still absorb a considerable amount of water, and activated alumina, especially silica gel, greatly lost the adsorption capacity.
