ActiveCarbon Fiber(ACF) is a new type of carbon fiber material prepared by an activated medium at a high temperature of about 900 °C under the protection of an inert gas after pre-oxidation or non-melting of carbon fiber at 250 °C -500 °C on the basis of high-performance carbon fiber. Active carbon fiber has unique physical and chemical structure and properties. The surface of the material is smooth and smooth. Compared with traditional activated carbon, it has a large surface area and pore volume, and the outer surface is more than 100 times larger than the traditional activated carbon. It has a highly developed microporous structure, narrow aperture distribution, and micropores open directly to the fiber surface. High adsorption capacity. The absorption and desorption are fast, conductive, low thermal expansion coefficient, corrosion resistance, and have better adsorption performance and adsorption Kinetics than traditional activated carbon. Active carbon fiber products include Maozhanbu, paper, Honeycomb, fabrics, messy short fibers and fiber bundles, etc.. The density is small, the molding is good, and it is not easy to powder, and the filling is not loose and excessively dense under vibration. phenomenon, It overcomes the problems such as grooves and subsidence in the process of operation of granular and powdered activated carbon, and has greater flexibility and simplicity in practical application. Active carbon fiber has the characteristics of large surface area, high strength, few impurities, high temperature resistance, corrosion resistance, and long service life. It has been hailed as one of the most advanced materials in the 20th century and has received great attention from various countries in the world and has been widely used in various fields..

Product characteristics

High adsorption capacity

Adsorption of activated carbon fiber has always been a hot topic in research and application. Various pollutants are rapidly and steadily concentrated in the activated carbon fiber micropores by filling the surface with multiple microholes. Active carbon fiber has a developed microporous structure and therefore has a large adsorption capacity. Active carbon fiber adsorbs several to dozens of times larger than conventional activated carbon, such as gasoline, aldehydes, alcohols, phenols, and olefins, and has good adsorption capacity for inorganic gases(such as NO, NOB2B, SOB2B, HB2BS, HF, HCl, etc.), The adsorption of substances in aqueous solutions(such as dyes, phenols, CODs, BODs, oils, volatile phenols, sulphides, iron ions, precious metal ions, etc.) is much higher than that of conventional activated carbon, and it is also good for microorganisms and bacteria. Adsorption ability.

Comparison of adsorption performance between activated carbon fiber and activated carbon particles

Fast adsorption speed

Active carbon fiber has a special pore structure, which makes its adsorption and desorption speed much faster than traditional active carbon. The surface of activated carbon fiber is mainly a micropore with concentrated aperture distribution. The adsorbent does not need to pass through a long distance hole and a transition hole to reach the microhole like activated carbon. Therefore, the diffusion resistance in the particle is small, so the adsorption speed is fast. The adsorption of gas can generally be achieved in tens of seconds or minutes. Balance. The adsorption of the liquid also takes only a few tens of minutes. For IB2B adsorption, activated carbon fiber conventional active carbon is 2-3 orders of magnitude faster. Similarly, the desorption path is short and the desorption speed is fast. At a certain temperature and time, activated carbon fiber can be completely desorbed, compared with the poor regenerative performance of traditional activated carbon materials, so active carbon fiber can be used to adsorb industrial exhaust gases containing different concentrations of organic solvents with high wind speeds. Inhalation phenomenon, After the adsorption is completed, the adsorbent can be desorbed and recycled for reuse.

Low concentration adsorption property is good

Adsorption to low concentration substances is particularly good. In surface absorption, the smaller the aperture, the larger the adsorption force field. Adsorption capacity is particularly good for low concentrations, even if the weight-weight adsorbents still maintain a high adsorption rate, while traditional activated carbon materials tend to have a significant decrease in adsorption capacity at low concentrations. Activated carbon loses its adsorption ability when the toluene concentration is less than 0.01 %, while activated carbon fiber still has a good effect at 0.001 %.

High Redox reaction activity

Active carbon fiber is not only an efficient physical adsorbent, but also has strong Redox properties. The Redox performance of activated carbon fiber is most obvious when it adsorbs metal ions from solution. It can reduce high metal ions to low prices in the process of adsorbing certain metal ions in aqueous solution. The Redox properties of activated carbon fiber are caused by a series of surfactant groups with different electrode potentials. Active carbon fiber can be used as a reducing agent or as an oxidant, depending on the potential level of the system used. The types and concentrations of groups involved in the reaction are the same, and the Redox capacity of activated carbon fibers is also different. Active carbon fiber has the function of gas catalytic Redox. NO can be reduced to NB2B in the presence of NHB3B by activating activated carbon fibers with HB2BSOB4B to give their surface catalytic capacity.
