Carbon molecular sieve utilize their screening properties to achieve the goal of separating O2 and nitrogen. When molecular sieves adsorb residual vapor, the pores and upright pores only have the effect of safe channels, which transfer the adsorbed molecules to micropores and sub micropores. micropores and sub micropores are considered the true capacity for adsorption.

Carbon molecular sieve contain many micropores on the outside, which allow small molecules of electrical energy to rapidly disperse into the pores, while limiting the entry of large-diameter molecules. Due to differences in the relative dispersion rates of vapor molecules with conflicting specifications, the composition of vapor impurities can be effectively separated.

The Production of carbon molecular sieves

Therefore, in the production and manufacturing of carbon molecular sieve, according to the size of the molecular specifications. The external micropores of the carbon molecular sieve dispersed within 0.2-0.38nm.

Within this micropore specification range, O2 can quickly deceive itself and disperse into the pores through the entire process of micropore opening.

While nitrogen is difficult to pass through the entire process of micropore opening and reach the separation of oxygen and nitrogen.

The diameter of micropores is the foundation for producing oxygen and nitrogen through the separation of carbon molecular sieves. If the diameter is too large, O2、 Nitrogen molecular sieves are very easy to enter the micropores. And not separated for production and manufacturing. And the diameter is too small, O2、 Nitrogen cannot enter the micropores and not separated for production and manufacturing purposes.

Precaution of Using Carbon molecular sieve in Nitrogen Generator

What are the common problems during the application of carbon molecular sieves in nitrogen production equipment? Let’s describe them in detail below:

1. After the gas expansion of the air compressor resolved, the vapor subjected to preparatory treatment, and water and oil prohibited from entering to avoid poisoning caused by alumina micro powder and activated carbon molecular sieves.
2. Ensure the reliability of the standard air pressure at the intake port and avoid fluctuations.
3. Pay attention to changes in the total flow rate of bloating gas.
4. Pay attention to the changes in nitrogen purity.
5. The nitrogen production equipment group well suited for continuous use.
