Structure and Properties Characterization of Coke Powder Activated Carbons

By chemical method coke powder activated carbons was prepared using coke powder as raw material and KOH as activator.The coke powder activated carbon with the optimum specific surface area as 185m2/g was obtained through orthogonal experiment with three factors and four levels.The influence degree of three factors on the adsorption of activated carbon powder was: activation temperature> alkali carbon ratio(KOH and coke mass ratio)>activation time.The samples before and after activation were comparatively de...
