Abstract Activated carbons were derived from peach stone shells by H 3 PO 4 -scheme under standard conditions: 50% H 3 PO 4 and pyrolysis for 2 h at 500 °C. Five carbons were prepared by changing the gas atmosphere during thermal treatment (no external gas, flowing of either nitrogen, carbon dioxide, steam or air). Additional carbon was obtained by extra-heat treatment at 800 °C of the standard carbon, for 2 h. Characterization was performed by adsorption of N 2 at 77 K, and testing of capacity… CONTINUE READING
