molecular sieve adsorbent application and sieves 4A molecules

Molecular sieve particles and the medium is a synthetic, molecular sieve aremicroporous aluminosilicate cubic lattice between particles and medium. On the basis of the crystal interior cavity size and adsorption or rejection of molecules of different substances, sieves 4A molecules, thus called "molecular sieve".Molecular sieve particles and the medium is less than the diameter of the aperture of molecular sieve crystal material can enter the crystal of the molecular sieve, molecular sieve adsorbent by adsorption, otherwise, sieves 4A molecular exclusion. Gas molecular sieve dehydration hydration according todifferent polarity molecules are molecular sieve adsorbent preferentially adsorbed order decision.molecular sieve natural gas dehydration select adsorption by molecular size and shape of different, de hydration is only adsorption are smaller than those of molecular sieve aperture molecular gas molecular sieve. Sieves 4A molecules for polarsmall molecules and unsaturated molecules, molecular sieve dehydration of natural gas hydrate production with the selective adsorption performance,sieves 4A molecular polarity is greater, increasing unsaturation, the selective adsorption is stronger. Zeolite molecular sieve which belongs to a kind ofmolecular sieve desiccant, and the structure of NaCl is very similar to natural gas hydrate, molecular sieve dehydration belongs to cubic. Molecular sieve drying the space network structure composed of silicon oxygen tetrahedronunit [SiO4] and tetrahedral [AlO4] units are staggered into. molecular sieves 4a and gasmolecular sieve dehydration of hydrated ion exchange properties, water softening function: natural gas molecular sieve dehydration every oxygen atomhydrated skeleton are two tetrahedral adjacent to the total, natural gasmolecular sieve dehydration hydration this structure form for Yang from thecrystal cave and water molecules occupy, natural gas molecular sieve dehydration hydration and these cations and water molecules have greatermobility, of cation exchange and reversible dehydration.
