The carbon molecular sieve (CMS) market has broad prospects and local companies have competitive advantages

Carbon molecular sieve (CMS), also known as nitrogen-generating molecular sieve, is an excellent non-polar carbon material and refers to a new adsorbent used to separate air and enrich nitrogen. Carbon molecular sieve is the main component of the pressure swing adsorption nitrogen generator, accounting for nearly 70% of its cost. The carbon molecular sieve nitrogen production process has the advantages of fast nitrogen production, low production cost, and high nitrogen recovery rate. It is widely used in food preservation, petrochemical industry, electronics and electrical, metal heat treatment and other fields.

According to the “2022-2027 China Carbon Molecular Sieve (CMS) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center It shows that the global carbon molecular sieve market size will reach US$2.11 billion in 2021, a year-on-year increase of 5.2%. After years of development, carbon molecular sieves have become the preferred pressure swing adsorption nitrogen-rich adsorbent for air separation in the engineering community. With increasingly strong downstream demand and continuous breakthroughs in production technology, the carbon molecular sieve market will usher in a period of rapid growth. It is expected that by 2027, the global carbon molecular sieve market will exceed US$3 billion.

Carbon molecular sieve products have broad application prospects in the fields of food preservation, petrochemical industry, electronic and electrical, metal heat treatment, environmental protection and other fields. In the field of food preservation, the principle of diffusion adsorption of carbon molecular sieves can be used to separate compressed air, nitrogen and oxygen, and can be used for fruit and vegetable storage, food nitrogen expansion, food packaging, etc.; in the field of environmental protection, carbon molecular sieves have separation, adsorption and catalytic properties. It can be widely used in exhaust gas purification, wastewater treatment and other fields.

The main preparation processes of carbon molecular sieve include carbonization method, carbon deposition method, gas activation method, thermal polycondensation method, template method, etc. Carbonization methods can be divided into organic additive modified carbonization methods, one-step carbonization methods and two-step carbonization methods. The two-step carbonization method is widely used. Using walnut shells, coconut shells, hawthorn shells, etc. as raw materials, carbon molecular sieves are obtained through carbonization. The carbon deposition method has the advantages of low production cost and simple operation, but has higher requirements on volatile content of raw materials; the carbon deposition method includes vapor deposition method and liquid deposition method, which requires strict control of temperature.

The major global carbon molecular sieve manufacturers include Japan’s Osaka Gas, Japan’s Kuraray, and Germany’s CarboTech. In recent years, the independent research and development capabilities of Chinese enterprises have continued to improve, gradually breaking the monopoly of overseas carbon molecular sieve brands. Jianlong Micro-Nano New Materials, Haihua Chemical, Jiuzhou Chemical, Shanli Chemical Materials, Minqiang Carbon Industry, etc. are the main suppliers of carbon molecular sieves in my country.

Industry analysts said that Japan and Germany have long held monopoly positions in the global carbon molecular sieve market, benefiting from the technological innovation of local companies, and my country’s High-end product quality and production technology have gradually reached the world’s leading level. As the prosperity of my country’s carbon molecular sieve industry continues to improve, product quality and quality have been greatly improved, and the products are exported to European and American countries.
