Activated carbon is a specially treated carbon, black, (activated charcoal, activated coal or active carbon), usually made of organic raw materials such as coconut shells, nut shells, coal, wood, etc., which are heated and carbonized in isolation from the air to reduce non-carbon components. , and then react with the gas, and the surface is eroded, producing a structure with developed micropores. Most of these micropores have a diameter between 2 and 50nm, which makes a small amount of activated carbon have a huge surface area and complex pore structure. The specific surface area of 1g of activated carbon is as large as a football field. Activated carbon is widely used because of its high adsorption performance. Applications. Such as gas purification and liquid purification, water treatment and purification, industrial desulfurization and denitrification, deodorization, and decolorization. At the same time, it is widely used in industries such as biogas, natural gas purification, gold refining, and food and beverage decolorization.
Highly porous structure: Activated carbon has a developed pore structure with moderate pore size, and can adsorb various organic compounds, heavy metals and other pollutants.
Extremely high surface area: Activated carbon has a large surface area, usually 1000-2000 square meters per gram of activated carbon, so it can carry a lot of substances.
Excellent adsorption: Activated carbon has strong adsorption performance and can adsorb organic matter, inorganic matter and microorganisms in gas, liquid and solution.
Excellent catalytic properties: Activated carbon can not only adsorb organic matter, but also provide catalysis, making the decomposition rate of organic matter faster. The catalytic effect is combined with the adsorption of substances, which has a dual effect.
Excellent compressibility and strength: Activated carbon has high compressibility and strength, is relatively light in density, has very high tensile and compressive strength, and is not easily broken and worn.
Chemical inertness and stability: Activated carbon is chemically inert and stable. It will not be corroded by strong corrosive substances such as acids and alkalis, and has good stability.
Excellent thermal stability: Activated carbon has excellent thermal stability and can be used at high temperatures without burning or oxidizing.
Wide range of applications: Activated carbon is widely used in water treatment, air purification, desulfurization and denitrification, solvent recovery and other fields due to its unique properties.
Raw material preparation: Select appropriate raw materials, such as coal, sawdust, fruit shells, coconut shells, etc.
Carbonization: heating raw materials to a certain temperature to cause carbonization reaction.
Cooling: Cool the carbonized material to a certain temperature.
Activation: Mix the cooled material with chemicals and undergo an activation reaction at a certain temperature to develop the pore structure of the material.
Washing: Use clean water to wash away the chemicals in the activated material.
Drying: Drying the washed materials.
Finished product processing: Process the dried materials into finished activated carbon products of different shapes.
Usually 1.8 tons-2 tons of raw materials can produce 1 ton of activated carbon.

The companies with the largest activated carbon production scale in the world are Calgon Carbon, Jacobi Carbon, and Sinou Carbon. The first two activated carbons that started earlier have obvious brand advantages. Sinou Carbon is made in China. Due to sufficient raw materials and economical benefits, it is currently the largest activated carbon manufacturer. China's top activated carbon company has rapidly entered the international market in recent years and has become a major manufacturer of activated carbon.
Sinou activated carbon is exported to Europe, Africa, the Middle East, America and other regions.
