Description
Carbon molecular sieve is a new kind of adsorbent developing from
***0, and is excellent non-polar carbon material. It can be used to
separate the nitrogen from the oxygen under normal temperature and
pressure (PSA). To compare with tradition, PSA (Pressure swing
adsorption at room temperature) has some advantages such as low
investment, short start-up time, high production rate and low cost
of nitrogen.
Carbon molecular sieve raw material is coconut shell, coal, resin,
etc.
Carbon molecular sieve utilize the different sizes of nitrogen
molecules and oxygen molecules to achieve the aim of separation of
the oxygen and nitrogen, in carbon molecular sieve internal
contains a large number of micropores, these micropores allow
oxygen molecules rapidly spread into them, but large diameter such
as nitrogen molecules are restricted into them. Aperture size is
the basis of carbon molecular sieve to separate oxygen and
nitrogen, if the aperture is too large, the oxygen nitrogen
molecules are easily into the pores, and if the aperture is too
small, the oxygen nitrogen cant spread into the pores, therefore
would not achieve the effect of separation.
Carbon molecular sieve processing steps:
The first step is to shape;
The second step is activation and pore-forming, spraying into
activator under **0~***0℃, commonly used activator is carbon
dioxide, oxygen, water vapor or mixture of them;
Step 3 is using chemical steam adjusting aperture size, for
example, used benzene vapor deposition in carbon molecular sieve
pore wall to control its micropore aperture distribution, and make
it in the range of 0.*8 ~ 0.*8 nm.
