As a highly efficient adsorption material, activated carbon has become a "jack of all trades" in the fields of environmental protection, industry and daily life due to its unique pore structure and chemical stability. In recent years, with the advancement of technology and the upgrading of environmental protection needs, the activated carbon industry has ushered in a new round of development opportunities. The following is the latest knowledge about activated carbon products:

• Core properties and production process of activated carbon

  Activated carbon is made through high-temperature carbonization and activation processes, and the raw materials include organic substances such as coal, wood, and coconut shells. Its adsorption capacity depends on the iodine adsorption value (the higher the better) and the pore structure. For example, coal-based activated carbon is widely used in industrial wastewater treatment because the raw materials are easy to obtain and have high strength; while coconut shell activated carbon has developed micropores and an iodine value of more than 1300mg/g, making it the first choice for high-end water and air purification.

• Diversified application scenarios of activated carbon

  1.Environmental governance:Activated carbon is used for deep purification of municipal sewage and industrial wastewater, especially for the adsorption of heavy metal ions (such as copper) and organic pollutants.

  2.Food and medicine:In the food industry, it is used for decolorization of syrup and purification of wine; in the pharmaceutical field, it is used for purification of antibiotics and production of injections.

  3.New Energy and Electronics:Supercapacitor activated carbon has become a key material in the energy storage field due to its high specific surface area (over 2000㎡/g), helping the development of new energy vehicles and renewable energy systems.

  
  

• Activated carbon product classification and technology upgrade

  1. Coal-based activated carbon:

  Using crushed coal as raw material, it has high strength and is easy to regenerate, but the production process consumes a lot of energy and faces pressure from environmental protection policies. 

  2. Wood-based activated carbon:

  Using agricultural and forestry waste as raw materials, it has low ash content and significant environmental benefits.

  3. Coconut shell activated carbon:

  It has excellent adsorption performance and an iodine value of over 1300 mg/g, but the cost is relatively high. Experiments show that its formaldehyde removal effect is significantly better than nano-activated carbon.

The activated carbon industry is transforming from traditional adsorption materials to green, high value-added fields. As the "dual carbon" goals are advanced, technologies such as biomass activated carbon and supercapacitor carbon will continue to make breakthroughs, injecting new impetus into environmental protection and energy revolution. Consumers and companies need to pay attention to product performance and technological innovation to jointly promote the sustainable development of the industry.
