What's the development status of carbon molecular sieve?

Here is the development status of carbon molecular sieves:

Global: The global carbon molecular sieve market sales reached $120 million in 2021. It is expected to reach $160 million in 2028, with a compound annual growth rate (CAGR) of 3.7% from 2022 – 2028.
China: As one of the largest carbon molecular sieve producers in the world, China has a huge production capacity and market demand. The domestic demand for carbon molecular sieves is also growing continuously. The main production areas are concentrated in coastal regions such as Hebei, Zhejiang, Anhui, and Shandong.

Air Separation: Air separation is the largest application field of carbon molecular sieves, accounting for approximately 60% of the market share. It is used to separate gases such as nitrogen and oxygen from the air and improve gas purity, and is widely applied in numerous industries including chemicals, oil and gas, electronics, food, and coal.
Hydrogen Recovery: It is used to recover hydrogen from gases such as coke oven gas, accounting for about 20% of the market share. With the development of the hydrogen energy industry, its application prospects in hydrogen – related fields are broad.
Other Fields: It is also used for air purification to remove harmful substances, sewage treatment to remove harmful substances in sewage for reuse, as well as separation and purification processes in industries such as chemicals, pharmaceuticals, and food.

International: The top five global manufacturers together account for approximately 60% of the market share. The main manufacturers include Osaka Gas Chemical, Kuraray, etc. The Americas is the largest carbon molecular sieve market in the world, accounting for more than 35% of the market share. Subsequently, the European and Asia – Pacific markets together account for approximately 60% of the share.
Domestic: There are about 14 carbon molecular sieve manufacturers in China, mainly distributed in Hebei, Zhejiang, Anhui, and Shandong. Enterprises such as Hebei Saisheng, with their strong comprehensive strength, have become industry leaders in terms of product output, variety, and quality. Imported products in the domestic market have gradually withdrawn.

Preparation Technology: Currently, the main methods for preparing carbon molecular sieves include chemical vapor deposition, templating method, sol – gel method, etc. The technological process is gradually simplified, the yield is continuously increased, and the cost is gradually reduced. However, challenges still remain in controlling the uniformity of pore size and specific surface area, and improving the stability of carbon molecular sieves.
Modification Technology: The modification methods mainly include acid treatment, oxidation treatment, metal ion modification, etc. The modification technology is constantly evolving, improving the adsorption performance and selectivity of carbon molecular sieves. However, the modification process may affect the structure and stability of carbon molecular sieves. How to maintain their original performance is a key issue in the modification technology.

Green and Environment – friendly: With the increasing awareness of environmental protection, the market demand for low – carbon and environmentally friendly adsorption materials will continue to grow. The industry will pay more and more attention to environmental protection and sustainability, promoting the application of green production technologies to reduce energy consumption and environmental pollution.
Intelligent Production: With the development of Industry 4.0, the carbon molecular sieve industry is expected to increase the application of intelligent manufacturing technologies to improve production efficiency and product quality.
Application Expansion: With the rapid development of emerging fields such as new energy and environmental protection, the applications of carbon molecular sieves in hydrogen energy storage and transportation, carbon dioxide capture and utilization, etc. will gradually increase, becoming important growth points in the future. ‘
