Product Name
Name：Carbon Molecular Sieve
Product Overview
carbon molecular sieves (CMS) is a carbon adsorbent with a relatively uniform microporous structure developed in the late 20th century. It has wedge slit micropores close to the diameter of the adsorbed molecules, which can separate the molecules with different three-dimensional structure sizes. Carbon molecular sieve is mainly based on the principle of gas molecular size, polarity and diffusion speed difference for gas separation, has the advantages of high adsorption strength, high hardness, heat resistance, acid resistance and chemical stability. As a new adsorbent, carbon molecular sieve is mainly used for the separation of some gas components in the air, and can also be used for the separation of some organic compounds. At present, it has been widely used in food hygiene, medical treatment, catalysis, air separation, nitrogen production, hydrogen recovery in coke oven gas and so on.

Product Features
High adsorption selectivity: The adsorption capacity of carbon molecular sieve for nitrogen is much higher than that of other gases, and nitrogen can be separated through selective adsorption, thus providing high purity nitrogen.
Rapid adsorption and release: The surface of the carbon molecular sieve has many micropores and mesoporous pores, and nitrogen molecules can quickly enter these pores, so as to achieve rapid adsorption. Similarly, carbon molecular sieves can release adsorbed nitrogen molecules very quickly, so that it can provide a continuous supply of nitrogen.
High storage capacity and long service life: Due to the large surface area and high selectivity of carbon molecular sieve, it can adsorb a large number of nitrogen molecules, and because of its chemical stability, high temperature resistance, corrosion resistance and other characteristics, the service life of carbon molecular sieve is relatively long.
Application Fields
Air separation: Carbon molecular sieves can be used to separate oxygen and nitrogen from the air, which is one of its main applications. Through pressure swing adsorption (PSA) process, carbon molecular sieves can efficiently adsorb oxygen and achieve nitrogen enrichment.
Petrochemical: In the petrochemical industry, carbon molecular sieves can be used for gas separation, purification and purification processes. For example, the removal of carbon dioxide and hydrogen sulfide from natural gas, and the separation of ethylene and propylene from petroleum cracking gas, etc.
Metal heat treatment: In the process of metal heat treatment, nitrogen is often used as a protective atmosphere. The carbon molecular sieve nitrogen machine can provide high purity nitrogen to ensure that the metal material is not oxidized during the treatment process.
Electronic manufacturing: The electronics industry has high purity requirements for nitrogen, and carbon molecular sieve nitrogen machines can meet this demand. Nitrogen is used in chip manufacturing, semiconductor packaging and other processes to prevent oxidation and contamination of products.
Food preservation: Nitrogen can be used for food preservation and storage to extend the shelf life of food. Carbon molecular sieve nitrogen machines can provide nitrogen for food processing and storage.
Hydrogen recovery: In some industrial processes, exhaust gas containing hydrogen is produced. Carbon molecular sieves can be used to recover these hydrogen and improve resource utilization.
Medical field: Carbon molecular sieves also have certain applications in the medical field, such as for oxygen concentrators to provide a high concentration of oxygen for patients who need oxygen inhalation.
