Activated Carbon - an overview ScienceDirect Topics

Carbon source, pyrolysis heating rate, peak pyrolysis temperature, and the activation process all affect the properties of the activated carbon to the extent that the BET surface area of the activated carbon can vary from 250 to 2410 m 2 /g and the pore volume can vary from 0.022 to 91.4 cm 3 /g (Ioannidou and Zabaniotou, 2007).
