Activated carbons from Uruguayan eucalyptus wood

摘要: Activated carbons were prepared from eucalyptus wood chars and the results of CO2, CO2-O2 steam activation compared. The carbonization step gave rise to a narrow micropore structure highly developed macroporosity which increased slightly upon CO2 significantly activation. This last process led also widening size distribution mesoporosity more than did. presence O2 accompanying in activating gas micro- carbons. No net destruction microporosity was observed even at high burnoff levels with as much 5 vol. % gas.
