Carbon Molecular Sieve is in black cylindrical appearance,It is a type of porous material accumulated by carbon element
and a type of new adsorbent for nitrogen separation.
Compare with traditional nitrogen making,using carbon molecular sieve for nitrogen making has a series of advantages,
low investment,low energy consumption,quick installation,high-degree automation,fast production.Therefore,carbon
molecular sieve become nitrogen separation most preferred adsorbent in industry fields.Nitrogen separated by carbon
molecular sieve is widely used in the industry of metallurgy,metal heat-treatment,chemical,medicine,pipeline transport,
oil extractions,storage and any other fields.
Working Principle
The principle of nitrogen separation by carbon molecular sieve is on the basis of gas molecule dynamics.In dynamics,gas
molecules diffusion rate is depend on its molecule size.
The size of oxygen molecule is smaller than the size of
nitrogen molecule.Thefore,oxygen molecule diffusion rate
is faster than nitrogen molecule.
Carbon molecular contain large number of micropores care
capable for the adsorption of gas molecules.When gas stream
flow through carbon molecular sieves,adsorption for oxygen
molecules reached saturation in a short time.But adsorption
for nitrogen molecules is limited.The mojority of nitrogen
molecules are separated from the gas mixture by carbon molecular sieves,Therefore,the product of nitrogen is enriched.
