PURPOSE: A process for preparing activated carbon using mineral oil, in particular bunker C oil and ferric sulfate is provided which can produce activated carbon having high activity at low cost. CONSTITUTION: A process comprises the steps of mixing 20 to 25% by weight of heavy oil (C35H72.C40H40) containing 85% by weight of carbon and 15% by weight of hydrogen with ferric sulfate, heating at 300 to 500°C and added with water when carbonization is completed, and filtering. The ferric sulfate in filtrate is mixed with an oxidizing agent such as H2O2, HNO3 and KNO3 to reuse. The heavy oil which is carbonized at high viscosity and high temperatures is used as raw material.
