The activated carbon was prepared by capsicum straw as the research object. The carbonization temperature, carbonization time and heating rate were taken as the influencing factors, and the specific surface area and char yield were taken as the test indexes of orthogonal experiment. The pore structure and surface chemical properties of activated carbon were characterized, which was prepared under the optimum carbonization process. The results showed that the optimum carbonization conditions were as follows: the carbonization temperature of 400℃, coking time of 50 min, heating rate of 5℃/min. Under these conditions, the char yield of activated charcoal was 39.900%, the BET specific surface area was 966.003 m2/g, the total pore volume was 0.544 cm3/g and the average pore diameter was 2.252 nm. Besides, rich pore structure and the functional groups such as phenol, alcohol hydroxyl, carboxyl, ether etc. existed in the surface of activated carbon.
