Palm shell was used to prepare activated carbon using potassium carbonate (K2CO3) as activating agent. The influence of carbonization temperatures (600-1000 degrees C) and impregnation ratios (0.5-2.0) of the prepared activated carbon on the pore development and yield were investigated. Results showed that in all cases, increasing the carbonization temperature and impregnation ratio, the yield decreased, while the adsorption of CO, increased, progressively. Specific surface area of activated carbon was maximum about 1170 m(2)/g at 800 degrees C with activation duration of 2 h and at an impregnation ratio of 1.0. (c) 2005 Elsevier Ltd.
