Granulation of Powdered Activated Carbon Generated
(Kim, 2009) Activated carbon exists in two common forms, powder activated carbon (PAC) and granular activated carbon (GAC) Usually, PAC has a better pore structure and surface area than GAC but due to simplicity of GAC use, its regeneration potential, and its granular structure makes it more practical for NOM removal than PAC (GAN et al, 2006)The hazardous waste activated carbon is "reactivated" and organic matter is changed into clean gas to save energy and reduce consumption； Low cost (The cost of tons of water is 30% 40% lower than that of powder activated carbon, heat loss less than 5%)颗粒活性炭吸附再生Activated carbon is an expensive product In most of the cases the cost of replacing the saturated carbon would be prohibitive It should therefore be regenerated, and four methods have been developed for this purpose: Steam regeneration; This method is restricted to regenerating carbon which has only retained a few very volatile productsRegeneration / Actived Carbon Lenntech

Adsorption on Activated Carbon – Part 1 Process
Adsorption on Activated Carbon – Part 1, M Tanzio 09/10/20 Background As a unit operation, many do not consider Adsorption a glamorous technology – “just put some charcoal in a drum and away you go!” But the physics involved and the engineering required for an effective system are quite challenging and sophisticated For a long Traditional activated carbon has been activated and processed porous carbon, which is in powder or granular form, while activated carbon fiber is fibrous, with micropores on the fiber, and its ability to adsorb organic gases is higher than that of granular activated carbon in the air Several to several tens of times, 56 times higher in aqueous The Classification of Activated Carbon – Okaysou
