Abstract (EN): The preparation of activated carbons from ground pine (Pinus pinaster) bark was studied, using pyrolysis at 600° C in a nitrogen atmosphere for 30 min, followed by activation in a carbon dioxide atmosphere, at temperatures from 800 to 1100°C, for 10 to 40 min. It was shown that the carbons activated at 1000 and 1100°C had excellent adsorption properties. Pine bark pyrolysed in the same way, and in an open pile along with untreated bark, was also compared with peat, on the basis of water-holding capacity and pore size, for its suitability as a soil conditioner. © 1984.
