The Durra (Sorghum) stalk was employed as a novel precursor for the formation of high surface area activated carbons (ACs) by utilizing ZnCl2 as activating agent followed by pyrolysis in a flow ofN2 gas. The formation of ACs has been investigated at different pyrolysis temperatures (400, 500 and 600 °C) and different ZnCl2 impreg- nation concentrations. The results indicated that, ...
