-
Gas-phase Adsorption: It is used for industrial waste gas treatment to adsorb harmful gases such as benzene, toluene, xylene, and formaldehyde, reducing air pollution. In the field of oil and gas recovery, it can recover volatile oil and gas, reducing resource waste and potential safety hazards.
-
Liquid-phase Adsorption: In the purification of drinking water, it can remove odors, residual chlorine, some heavy metal ions and organic pollutants in the water. In the sewage treatment process, it has a certain adsorption and removal ability for pollutants such as COD and BOD in sewage, improving water quality.
-
Catalyst Carrier: With its good adsorption performance and stable chemical structure, it can carry active components such as metal catalysts and is used in chemical synthesis, environmental protection catalysis and other reaction processes to improve reaction efficiency and selectivity.
-
Excellent Adsorption Performance: The abundant pore structure endows it with a powerful adsorption force for multiple substances, enabling it to effectively remove target pollutants and achieve remarkable purification effects.
-
Selective Adsorption: It can conduct selective adsorption on substances with different molecular sizes and polarities according to the pore size and surface chemical properties, improving the pertinence and efficiency of adsorption.
-
Economical and Practical: It has a wide range of raw material sources, relatively low production costs, and a long service life, showing good cost-effectiveness during long-term operation.
-
Good Regeneration Performance: Through appropriate regeneration methods such as thermal regeneration and chemical regeneration, part of its adsorption performance can be restored, realizing multiple cycles of use and reducing resource consumption.
-
Physical Characteristics: It has a regular columnar shape, a well-developed internal pore structure, including micropores, mesopores and a small number of macropores, with a wide range of pore size distribution. Its specific density is moderate, approximately 0.4 - 0.6g/cm³.
-
Chemical Characteristics: It has stable chemical properties and is not easy to undergo chemical reactions under general acid-base environments. It can withstand certain temperature changes, but its structure may change and its performance may decline under high temperatures (such as above 800℃) and the action of strong oxidants. Its surface has certain functional groups such as carboxyl groups and hydroxyl groups, which can participate in some adsorption and chemical reaction processes.
Firstly, the raw materials are pretreated by screening, crushing, drying, etc. Then, carbonization is carried out under anaerobic or oxygen-deficient conditions to make the raw materials initially form a carbonaceous structure and release volatile components. Next, activation is carried out under high temperature and with the action of activators (such as steam, carbon dioxide, etc.) to further expand the pores, increase the specific surface area and adsorption performance. After that, post-treatment processes such as screening, impurity removal and packaging are carried out on the activated products to obtain columnar activated carbon finished products that meet the quality standards.
