摘要：

High-surface-area activated carbons in granular form were prepared by chemical activation of pistachio-nut shells with potassium hydroxide. The effects of the preparation variables on the carbon pore structure were studied in order to optimize these parameters. It was found that the chemical to shell impregnation ratio, the activation temperature and the activation hold time were the important parameters that affect the characteristics of the activated carbons produced. For the experimental parameters investigated, the optimum conditions for preparing activated carbon with a high surface area and pore volume were identified. (C) 2003 Elsevier Inc.
