Seed hulls (or coats) of peanut, soybean, cottonseed, lupine, broad beans, and sunflower seeds, were subjected to various treatments in order to get adsorbing carbons. Characterization of porosity was determined by N 2 /77K adsorption isotherms. Simple pyrolysis at 500°C yields low adsorbing carbons of meso-/macroporous character, whereas steam activation of these chars at 850°C enhances porosity,...
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 2h 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...
