Nitrogen carbon molecular sieve, also known as Carbon molecular sieve nitrogen generator, has a CBNumber of CB71173803. It is a crucial material widely used in various industrial applications due to its unique properties.

Properties of Nitrogen Carbon Molecular Sieve

• Adsorption Property: The dynamic adsorption property of radon and xenon on carbon molecular sieve is distinctly different, which can be used to separate radon from xenon. Also, the adsorption and diffusion of oxygen and nitrogen in carbon molecular sieves used for air separation have been studied, and the results indicate that the diffusion process of oxygen and nitrogen in carbon molecular sieve is activated, which may be represented by the dual diffusion resistance model.
• Gas Permeation Mechanism: Characteristics, preparation and gas permeation mechanism of molecular sieve carbon membranes are discussed. Computer simulation of the mechanism of gas separation through carbon molecular sieve membranes (CMSM) has been developed in recent years, including the development and choice of simulation methods, and the non-equilibrium molecular dynamics method. 

Preparation of Nitrogen Carbon Molecular Sieve

The method for preparing the coal-based carbon molecular sieve has rich source of preparation raw materials and low cost. For carbon molecular sieve membrane, it can be prepared with coating solution of novolac phenol formaldehyde (PF) resin containing hexamine on the outer of green support from the same material.

The carbon molecule sieve membrane was prepared by coating, drying and one-step carbonization. It is effectively solved the problem that the separation layer is prone to pinholes and cracks in the preparation of carbon membranes.

Applications of Nitrogen Carbon Molecular Sieve

• Air Separation: The compressed air after removing oil, water and dust enters the absorption container of the nitrogen generator. In this, there is a carbon molecular sieves separating oxygen and nitrogen in the air. Experimental study on separation of oxygen and argon by carbon molecular sieves has also been conducted.
• CA Storage: Carbon molecular sieves nitrogen generator can be successfully used in CA storage of ‘Red Delicious’ apples in natural air cold storage (15 – 0℃).
• It can strongly inhibit the conversion of ACC and the production of ethylene in fruit tissue. It can maintain fruit quality, reduce weight loss rate, effectively control the occurrence of disease, and extend the shelf life.
• Gas Purification: Purification processes using dry media, such as activated charcoal (carbon) or molecular sieve. This may be subject to rapid exotherms from sudden exposure of the media to large quantities of NF3. In addition, a method for producing a mixture of ethylene and carbon monoxide comprises contacting ethane. And an oxygen source with a catalyst comprising synthetic cryptomelane or octahedral molecular sieve. Also, the recent progress of adsorption desulfurization of gasoline using adsorbents based on activated carbon, molecular sieve, metal oxide and clay materials was reviewed
