Carbon Molecular Sieve

Carbon molecular sieve is a type of new adsorbent, it is the most preferred adsorbent for psa nitrogen separation.
INQUIRY

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.

Regeneration

So called regeneration, in actual is to restore the adsorption capability of carbon molecular sieve to its normal standard by the method of activation.

In long time use process,micropores of carbon molecular sieve are clogged by its excessive adsorbed moisture,rare gases and greasy substances from the air.This phenomeno is called carbon molecular sieve poisioning.Once the micropores are clogged,carbon molecular sieve adsorption capacity would reduce gradually,therefore,result in the deduction of nitrogen productivity and increasing of energy consumption.

Regeneration technology for carbon molecular sieve is a new technology, it is research and developed by ourself according to market demand.

According to feeback from end user and test result from state test center, it is proved that the regenerated carbon molecular sieve adsorption performance could completely retored to normal standard.

The birth of this technology made carbon molecular sieve recycle use come true.It not only effectively protected the natural environment, but also greatly reduced the production cost for the nitrogen production.
