Scientific knowledge about activated carbon filter materials

Activated carbon filter material with high specific surface area and pore volume, is one of the traditional chemical adsorbent, in recent years, the activated carbon fiber and textiles caused the extensive concern of the industry, the textile material into activated carbon fiber/textile manufacture and polymer thermal chemical process combination of cutting-edge technology. Then discussed with textile technology, thermal chemical process, material structure and properties of activated carbon materials science and engineering characteristics, in order to give people a feeling of production cost and benefit, the activated carbon fiber and the production cost of granular activated carbon were compared. Activated carbon is inert, carrier and active phase ( Most precious metals) The interaction between small, therefore, compared with the other carrier, active carbon carrier have less effect on the quality of metal, because of inertia, hardly showed the activity of acid catalyst, activated carbon decomposition of hydrocarbons, lead to carbon deposition on the metallic, cause catalyst poisoning. In contrast to the stability of the oxide carrier activated carbon has an aggressive in acidic and alkaline solution, and because of that, activated carbon is often used in corrosive liquid reaction, activated carbon can be used in high temperature in an inert atmosphere, because does not deformation at high temperature. Steam activated carbon in much higher than 900 ℃, the activation temperature stability.
