China Carbon Molecular
Sieve Co., Ltd. manufactures carbon molecular sieve(CMS) for separation
methane with high methane recovery rate over 97% and with purity 99.5% methane.
Due to the dynamic diameter of CO2, N2 and methane(CH4) are
0.33nm, 0.36nm and 0.382nm. The physical and chemical properties of CO2, N2 and
methane(CH4) are similar. but their kinetic diameters are different in
separation operations, The diffusion rate of CO2, N2 in carbon molecular sieve(CMS)
for methane(CH4) much greater than the diffusion rate of CH4. Based on the
kinetic principle, most of the CO2 and N2 are adsorbed by carbon molecular sieve
in the initial stage of adsorption, and CH4 is directly enriched in the overhead
gas.
Efficient carbon molecular sieve(CMS)
for methane(CH4) and PSA generator purification
and separation technology can improve the treatment of shale gas The recovery
rate of low-concentration CH4 in coalbed methane and landfill gas is meaningful
to alleviate the contradiction between energy supply and demand. improving the
atmospheric environment.
Therefore, the pressure swing adsorption method is an effective method for
separating CO2, N2 and methane(CH4) by be using carbon molecular sieve(CMS)
for
methane(CH4) as the adsorbent, which increase the recovery rate of methane(CH4).
China Carbon Molecular Sieve Co., Ltd. uses high-purity raw materials through
carbonization and chemical vapor deposition of CH4 to realize the control of the
microporous structure, and prepares carbon molecular sieve for methane(CH4) with
uniform pore size, with a microporosity of 93%, and it is very effective for CO2/CH4,N2/CH4 has good separation ability and high CH4 recovery rate. When the
pore size diameter of our carbon molecular sieve(CMS)
for methane(CH4) is 0.35nm, the
(N2,CO2)/CH4 separation coefficient is as high as 13.6, and the recovery rate is
over 97%.
