     Improve the quality of carbon molecular sieve for N2 (CMS for N2).
     By selecting appropriate raw materials, grinding and carbonization processes, finely controlling carbon deposition and adjusting the aperture diameter of carbon molecular sieve, we will increase nitrogen yield and service life, and reduce the air consumption.
    High-performance carbon molecular sieve for N2 are: 1. High nitrogen yield, each ton of carbon molecular sieve (CMS for N2) produces a certain concentration of nitrogen yield per hour. 2. Air consumption, to produce a certain concentration of nitrogen production, how much air is consumed per hour. 3. Service life.
     People expect high-performance carbon molecular sieve for N2 (CMS for N2) to have high nitrogen yield, low air consumption and long-term service life.
     1. China Carbon Molecular Sieve Co., Ltd. found that the lower the ash content of inorganic salts in carbon molecular sieve raw materials, the higher the ability of carbon molecular sieve to separate nitrogen and oxygen. We use pure coconut shell and phenolic resin as raw materials to make carbon molecular sieves to achieve high nitrogen yield.
      2. China Carbon Molecular Sieve Co., Ltd. found that the larger the specific surface area and pore volume, the more uniform the micropores of 3-5a, that is, the higher the nitrogen output and the lower the gas consumption of carbon molecular sieve. In order to obtain high-performance carbon molecular sieve with high nitrogen yield (CMS is used for N2), reduce air consumption. By selecting the appropriate carbonization process and finely controlling the carbon deposition process, the pore size of the carbon molecular sieve can be controlled to be more uniform. By carbonization or activation and vapor-phase carbon deposition methods, We prepare carbon molecular sieves for nitrogen with uniform pore size, with a microporosity of 93%, which is suitable for large-capacity pressure swing adsorption and separation of carbon molecular sieves with high adsorption capacity and selectivity.
     It is better to use this method to obtain nitrogen with low air/nitrogen ratio and high nitrogen yield and can produce 99.999% N2.
       3. The service life of carbon molecular sieve is related to its hardness, water resistance and oil resistance. Since the amount of oil and water in the compressed air is small, pulverization will affect the pore size of 3-5a, so the use of carbon molecular sieve for N2 will affect the water resistance and oil resistance of carbon molecular sieve.
.       By selecting appropriate pure raw materials and passing appropriate grinding, grinding and coating processes; controlling the carbon deposition and pore size of high-performance carbon molecular sieves to increase nitrogen yield and carbon molecular sieve air consumption (CMS is used for N2)
      Our high-performance carbon molecular sieve for N2 has the characteristics of high nitrogen production, low air consumption, long service life and energy saving.
