Carbon molecular sieves have good adsorption, catalytic and ion exchange characteristics, and are widely used in adsorption, ion exchange, catalysis and other fields.
1. The molecular sieve of the nitrogen generator has strong water absorption: it should not be immediately exposed to the air when it is stored. They should be kept in a dry place. Long-term storage time. Molecular sieves that have been wet for a long time need to be regenerated during use.
2. In the pressurized regeneration link of the molecular sieve tower of the nitrogen generator, the internal loss of the tower should be discharged slowly. If blood pressure is lowered too quickly, the carbon molecular sieve particles may be crushed and stratified. The higher the regeneration temperature, the safer the regeneration, but the greater the regeneration heat consumption, the service life of the molecular sieve may be reduced. Therefore, the regeneration temperature of 200-350 °C should not exceed 600 °C, otherwise, the molecular sieve will lose its vitality.
3. Prevent oil and liquid water in the carbon molecular sieve: Oil will block the pores of the molecular sieve. Especially during the regeneration process, the oil may charred and clog the pores. For oily vapors, gas, oil and water separators should be used before molecular sieve columns. Because molecular sieves release heat when they absorb water, liquid water releases a lot of heat when it immediately touches a molecular sieve. This may lead to risks or damage to the characteristics of the zeolite.
In the past, we introduced how to solve the application problems of carbon molecular sieves in nitrogen generators, and through the above introduction, we learned about the various properties and storage methods of carbon molecular sieves. When storing carbon molecular sieves, please refer to the above methods. You should put it in a dry environment and pay attention to regeneration. If the regeneration temperature is not well controlled, the carbon molecular sieve may be inactivated, so it should be carefully controlled. In addition, in actual operation, it is necessary to strictly implement the requirements and do not do some operations casually, so as not to affect its characteristics.
