In this work the potential application of olive biomass in the elaboration of activated carbon, is evaluated. The raw materials used were olive bone extracted from the alperujo and pruning wood of the olive grove, whose characterization was carried out on the basis of preliminary tests and their content in lignin, cellulose and hemicellulose. The activated carbon (c.a.) was obtained in two stages, carbonization and activation step. The carbonization was carried out in an inert atmosphere at 600 °C and the activation process consisted of a pyrolysis at different temperatures (from 280 °C to 900 °C) with carbon dioxide or air as activators.They were characterized by dry basis carbon yield (YC), Electronic Scanning Microscopy (SEM), Electron Microsound (EDS), Specific Surface Area (BET) and iodine index determination. Better activated carbon was achieved by activation with carbon dioxide.
