China Carbon Molecular Sieve Co., Ltd. has long
been engaged in the research and productes Lithium molecular sieve for oxygen
production
People hope that carbon molecular sieve has high nitrogen yield, long service
life and low raw gas consumption. In order to increase the nitrogen yield, the
diameter of the carbon molecular sieve(CMS) is
reduced. People make carbon molecular sieve with a diameter of less than 1.1mm.
However, in the process of using carbon molecules(CMS),
if the oil and water in the air enter the carbon molecular sieve, the carbon
molecular sieve(CMS) absorbs
water and oil, which will gradually reduce the nitrogen yield and service life
of the carbon molecular sieve and the nitrogen generator. In addition, the
flushing of the airflow will cause The pulverization of carbon molecular sieve
will also reduce the nitrogen yield and service life of the nitrogen generator.
Therefore, the carbon molecular sieve(CMS) must
be vibrated and compacted when it is loaded into the adsorption tower of the
nitrogen generator. In the process of use, the air entering the carbon molecular
sieve in the adsorption tower of the nitrogen generator is usually first dried
and purified to control the oil in the air. And the water content is below 3ppm.
The carbon molecular sieve itself should also have high strength, suitable water
and oil resistance. Thereby improving the service life of carbon molecular
sieve. However, carbon molecular sieves with small diameters have lower strength
than carbon molecular sieves with large diameters, and carbon molecular sieves(CMS) have
a shorter service life.
China Carbon Molecular Sieve Co., Ltd. found that increasing the nitrogen yield
of carbon molecular sieves can also be achieved by selecting appropriate pure
raw materials. The lower the ash content of inorganic salts in the raw materials
for carbon molecular sieves, especially sodium ions The smaller the content, the
higher the nitrogen yield, water resistance and oil resistance of the carbon
molecular sieve, and the longer the service life. Secondly, the raw material
powder should be crushed and ground to less than 3 microns. The finer the raw
material powder, the higher the strength of the carbon molecular sieve(CMS).
The higher the nitrogen production rate and the higher the water and oil
resistance of the carbon molecular sieve, the longer the service life.
Therefore, the nitrogen yield of our carbon molecular sieve with a diameter of
1.2-1.8mm is the same as that of a carbon molecular sieve with a diameter of
less than 1.1mm, but the strength of the carbon molecular sieve(CMS) is
greatly improved and the service life is long.
Finally, China Carbon Molecular Sieve Co., Ltd. adopted a suitable coating
process to improve the water resistance and oil resistance of the carbon
molecular sieve(CMS) and
increase the service life of the carbon molecular sieve.
China Carbon Molecular Sieve Co., Ltd. uses pure raw materials that do not
contain inorganic salt ash, advanced hole adjustment technology, advanced
grinding and coating processes to produce carbon with a diameter of 1.2-1.8mm
with long service life, high nitrogen yield and low air consumption. Molecular
sieve. It has the same nitrogen yield as carbon molecular sieve with a diameter
of less than 1.1mm, but the strength is greatly increased and the service life
is increased.
