1. The adsorption principle of coal columnar activated carbon adsorbent:

Coal-based columnar activated carbon is a kind of activated carbon that is mainly made of high-quality anthracite as raw materials. It has a black appearance, developed internal pore structure, large specific surface area, and strong adsorption capacity. There are a large number of micropores invisible to the naked eye in the columnar activated carbon material. The surface area of ​​the micropores in 1 gram of activated carbon material can be as high as 800-1500 square meters after unfolding, and it is even higher for special purposes. In other words, in an activated carbon particle the size of a rice grain, the inner surface area of ​​the micropores may be equivalent to the size of a living room area. It is these highly developed, human capillary-like pore structures that enable activated carbon to have excellent adsorption performance, and therefore it is used as a good adsorbent. To

2. Features of coal columnar activated carbon adsorbent:
To
1) The advancement of coal-based columnar activated carbon as an adsorbent: Coal-based columnar activated carbon is made of high-quality anthracite as raw materials and refined through a series of production processes. It has large specific surface area, developed pore structure, strong adsorption capacity, and high mechanical strength. It is not easy to break, easy to regenerate repeatedly, and can achieve maximum adsorption and desorption, thus greatly improving the service life of the product (average 2-3 years), which is 1.4 times that of ordinary coal-based carbon.

2) Applicability of coal columnar activated carbon adsorbent:
①Used for liquid and gas phase adsorption;
②Used for the recovery of organic solvents;
③Used for the treatment of impurities, toxic gases and industrial waste gas;
④Used for recovery of excessive gasoline in refineries, gas stations, and oil depots;
⑤Used to catalyze the removal of HCl from tetrachloroethane to prepare trichloroethylene by activated carbon

3. Application of coal columnar activated carbon adsorbent:

Coal-based columnar activated carbon has good adsorption capacity due to its strong specific surface area and developed pore structure, so there is a saying that activated carbon is an adsorbent. As an adsorbent, it is widely used in daily life, industry and agriculture. But what are the specific fields of application of coal-based columnar activated carbon? We can take a look together.

1) On liquid phase adsorption:
① Food industry: used for the purification, decolorization and refining of alcohol and sucrose;
②Chemical industry: used for decolorization of organic matter;
③Environmental protection: used for the treatment of domestic and industrial sewage, wastewater and drinking water;
④Other aspects: used for recovery and extraction in the metallurgical industry.
To

2) On gas phase adsorption:
①Industry: used in the purification treatment of industrial toxic gases, industrial waste gas, etc.;
②Special application: used for gas masks or gas masks;
③Other applications: cigarette filters
