Optimized preparation of activated carbon with high porosities based on puck shells (Afrostyrax lepidophyllus) by response surface methodology and physico-chemical characterization.

ABSTRACT: From recent research, lignocellulosic materials assert themselves as good precursors for the manufacture of highly carbonaceous and porous materials. Hence, the perspective of this work is the preparation of the low-cost activated carbons (ACs) based on puck shells (Afrostyrax lepidophyllus) with a large surface area. To achieve this, chemical activation using phosphoric acid and sodium hydroxide as an activating agent was carried out. The response surface methodology through Box-Behnken design was used to optimize the preparation conditions. Box-Behnken design was used to optimize the preparation conditions. The factors whose influences have been studied are the concentration of activating agent (0.5-1.5 mol l^-1), the carbonization temperature (300-500°C) and the residen
