Activated Carbon Fiber (ACF)

ACF Fabric

ACF Felt

ACF Non-woven

ACF Tow

　　KoTHmex® Activated Carbon Fiber (ACF) is a new highly efficient functional adsorbent material. It can be made into different patterns like felt and fabric. Compare to Granulated Activated Carbon (GAC), the efficiency of adsorption systems of KoTHmex® ACF is higher and it is easy to be used。

　　 KoTHmex® ACF provides widely applications such as industrial processing, environmental protection, absorptive material for medical using.

‧Properties of Activated Carbon Fiber (ACF)

　　The surface area of KoTHmex® Activated Carbon Fiber (ACF) is extremely large and its micro pore configuration is similar to long and narrow. This makes the capacity of adsorption large. Physical adsorption of ACF makes its regeneration and degeneration process outstanding and Below are its characteristics：

‧	ACF’s large surface area and average aperture of micropore makes its fast speed of adsorption and desorption。
‧	ACF also has excellent adsorption to low concentration substance, because its adsorption forces and unit adsorptive volume。
‧	The good tensile strength of carbon fiber can be made into different patterns, like paper, non-woven, a honeycomb structure and corrugated cardboard。
‧	ACF itself is not easy to become powder so it will not cause second pollution。
‧	It can reach to the expectable efficiency in short time because its Low density and small loss of press。
‧	ACF’s thin and light adsorption layer allow it be used in the small treatment with high efficiency。
‧	ACF can also be applied as fuel cell electrodes material。
‧	Without reducing it’s adsorption function, its easy to be regenerated. And it can be used for very long time。
‧	Ozone Removal application。
‧	ACF has also a function of bacteriostasis。
‧	ACF can be a deoxidizer to recycle the precious metal。
‧	acid-proof, alkali-proof。

‧Recovery of Organic Compounds and Solvents：
　　ACF can be used in gas / air separation, recovery of organic compounds and solvents, especially for caustic nitrides, reaction solvent、low boiling point solvent; The speed of adsorption and desorption are fast and the percentage of recovery can be reached to 97%。
‧Air purification：
　　ACF can eliminate malodorous substance in the air, especially for aryl substance which will generate carcinogens。
‧Wastewater treatment：
　　ACF is also suitable to be applied in organic wasterwater treatment, like substance content phenol, medical waste,etc. which are hard to decompose by organism. With large quantity of adsorption volume, fast speed of adsorption, excellent desorption function, and easy to regenerate, ACF can be used in a small, continuous, simple design condition which cost low and do not make second pollution。
‧Water purification：
　　Deodorizing and decoloring Applications in different industrial field, like food and beverage, pharmaceutical, sugar-making, wine-making. Besides, it also can be applied in super-pure water treatment system of electronic industry and aqueous filtration treatment etc。
‧Domestic products：
　　ACF can be a refrigerator deodorizer and keep food fresh。
