Physical activation of petroleum coke was investigated at 800°C, at different carbonization and activation times. Also, chemical activation of petroleum coke and the coke produced from co-coking of decant oil and bituminous coal was investigated at 700°C. For the chemical activation, the coke was chemically activated with KOH. Mixtures of KOH and coke at 4:1 ratio were prepared for activation. The pore characteristics of activated carbons and their differences from the parent coal were investigated. It was found that physical activation is ineffective for activating of petroleum coke samples. High surface area (1948 m2g-1) activated carbon was developed by chemical activation.
