Activated carbon is a higher carbon content and voids more developed substances, such as coal, shell, wood, bone, petroleum residues as raw materials, the first after carbonization, and then after 800 to 1500 degrees of heat activation treatment, the formation of well-developed micro- hole and the hole, making it the specific surface area and adsorption capacity of certain requirements. Normal production of activated carbon is generally divided into two processes: Firstly, charring, Second: activation. Han research into activated decolorizing charcoal, activated carbon water purification, air purification activated carbon, activated carbon and hundreds of metal recovery types, uses and widely used, is present scientific level can achieve the most effective adsorbent material. Air purification activated carbon [1]: a cylindrical activated carbon. High quality activated carbon is a special treatment for special purify polluted air. Only hardness, high strength, porosity of microporous activated carbon can be used as carbon air purification. Shell charcoal, coal can be used as carbon air purification materials. Coconut shell activated carbon which works best. Air purification activated carbon, high-quality wood or coconut shells, through activation of the depth and diameter adjusting our unique process, the activated carbon has a wealth of holes and hole size slightly larger than the toxic gas, the specific surface area> 1300 square flat / g, for benzene, a Chuo, ammonia and other toxic gases with high efficiency adsorption capacity, can effectively remove indoor air pollutants and harmful gaseous odorous substances, and thus to reduce pollution, air purification purposes. Division I launch different applications according to spherical, cylindrical two specifications of products, it is easy desorption regeneration, loss, compared to conventional granular or powdered activated carbon have a higher life, can greatly reduce the user cost. Therefore, regardless of performance or on the consumer perspective, the best air purifier simply shot the lights activated carbon filter.
