Granular activated carbon (GAC) is mainly used in the field of VOCs treatment. The high-end competitiveness of local enterprises needs to be improved.

​​According to different appearances, activated carbon can be divided into two types: powder activated carbon and granular activated carbon. Granular activated carbon (GAC) is also called granular activated carbon. Compared with powdered activated carbon, it has the characteristics of larger particle size and larger monomer volume. It is widely used in water treatment, VOCs treatment, petrochemical industry, military and national defense, food processing, medical and other fields. .

​According to different raw materials, granular activated carbon can be divided into three types: coal-based granular activated carbon, coconut shell granular activated carbon, and fruit shell granular activated carbon. Coal-based granular activated carbon is a representative product in the granular activated carbon market. It is made from coal as raw material and can be subdivided into two types: amorphous granular activated carbon and shaped granular activated carbon; coconut shell granular activated carbon has high strength, good adsorption performance, and is green and environmentally friendly. Advantages, it is an emerging product in the granular activated carbon market; Guoke granular activated carbon uses high-quality fruit core shells as raw materials and is widely used in the field of water treatment.

The main preparation methods of granular activated carbon include binder method and binder-free method. The binder method refers to using sulfite pulp waste liquid, starch, waste molasses, wood tar, carboxymethyl cellulose, etc. as a binder. The raw materials are crushed and then bonded with the binder to achieve the molding effect. Carbonization and other processes are used to produce finished products; the binder-free method can be divided into two types: chemical activation method and direct activation method. The chemical activation method has the advantages of short reaction time and easy parameter control, and is widely used in the production process of granular activated carbon. .

According to the “2023-2028 China Granular Activated Carbon (GAC) Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center It shows that granular activated carbon is widely used in water treatment, VOCs treatment, petrochemical industry, military and national defense, food processing and medical treatment. In the field of VOCs treatment, granular activated carbon can be used to treat low-concentration, high-volume organic waste gases. Chemical plants, food processing plants, rubber factories, etc. are its main application scenarios. In recent years, benefiting from national policy support, the development of my country’s VOCs treatment industry has accelerated, driving further growth in the market demand for granular activated carbon.

Changzhou Leiterui Environmental Protection Technology Co., Ltd., Shandong Tansuo Activated Carbon Co., Ltd., Fujian Xinsen Carbon Co., Ltd., Fujian Yuanli Activated Carbon Co., Ltd., etc. are the main manufacturers of granular activated carbon in my country. Compared with overseas developed countries, there are gaps in my country’s granular activated carbon companies in terms of production scale, equipment quality, and degree of automation. Mid- and low-end products occupy a larger share of the Chinese market.

Industry analysts said that thanks to the gradual implementation of national environmental protection policies, granular activated carbon has been widely used in the field of VOCs treatment. The sufficient supply of raw materials and the improved technological maturity of local enterprises have laid a good foundation for the development of my country’s granular activated carbon industry. However, at present, Chinese companies are focusing on the production of mid- to low-end granular activated carbon, and the market share of high-end products still needs to be increased.
