Introduction To Air Purification Activated Carbon

Jul. 20, 2018

Activated carbon contains more than 90% carbon, has developed micropores, and has a surface area of 500~2000 square meters/g. It has strong adsorption capacity and is one of the better adsorbents. The physical and chemical properties of activated carbon are relatively stable, insoluble in water and organic solvents, resistant to acid and alkali, and subjected to water, high temperature and high pressure. It is easy to regenerate after use, so it is widely used in sugar, pharmaceutical, and MSG industries. It is used as a catalyst and catalyst for chemical fiber chemical industry. It can be used for solvent purification, air purification, water treatment and other environmental purification. It can also be used for user anti-virus masks. Anti-atomic radiation and other defense industries, as well as agriculture and other industries.

The types of activated carbon are as high as 200~300. At present, the raw materials of activated carbon produced in China are mainly plant raw materials (accounting for more than 60%). Most of the activated carbon is Wooden Activated Carbon, and a small amount is corn cob. The wood raw materials are each produced by drug activation and gas activation. For gas activation, the wood material should be carbonized before it can be activated. Therefore, before introducing the carbonization process and equipment classification, we introduce the classification of wood raw materials, as well as the basic theory of wood carbonization process, products, chemical evolution from wood to charcoal, activated carbon, and the structure of activated carbon.

The production of ordinary activated carbon is generally divided into two processes, first: carbonization, and second: activation. Activated carbon is divided into dozens of types such as decolorized activated carbon, water-treated activated carbon, air-purified activated carbon, and heavy metal-recovered activated carbon. It is widely used and is the most effective adsorbent material that can be achieved at the current scientific level.

Air Purifying Activated Carbon: is a cylindrical activated carbon. It is a special quality activated carbon specially treated to purify the polluted air. Only activated carbon with high hardness, high strength, high porosity and developed micropores can be used as air purifying carbon. Shell charcoal and coal can be used as air purification carbon materials. Among them, coconut shell activated carbon has the best effect.

Air purification activated carbon, using high quality wood or coconut shell, through deep activation and unique pore size adjustment process, the activated carbon has abundant pores, and the pore size is slightly larger than toxic gas, the specific surface area is >1300 square meters / gram, for benzene, Formaldehyde, ammonia and other toxic and harmful gases have high-efficiency adsorption capacity, which can effectively remove gaseous pollutants and harmful odorous substances in indoor air, thereby achieving the purpose of reducing pollution and purifying air.
