Title (EN) ACTIVATED NUTSHELL CARBONS WITH ENHANCED REMOVAL OF POLAR ORGANICS
(FR) CARBONES DE COQUILLE DE NOIX ACTIVES AVEC ELIMINATION AMELIOREE DE COMPOSES ORGANIQUES POLAIRES
Abstract:
(EN) Activated carbons derived from lignocellulosic nutshell waste, and for use in absorption of polar organic compounds, are prepared utilizing carbon dioxide or steam activation at 800 °C to 900 °C for 3 to 8 hours and subsequent oxidation with air at 260 °C to 400 °C for 3 to 6 hours.
(FR) La présente invention concerne des carbones activés dérivés de déchets lignocellulosiques de coquille de noix, utilisés dans l'absorption de composés organiques polaires, et préparés à l'aide d'une activation de dioxyde de carbone ou de vapeur à des températures allant de 800 °C à 900 °C pendant 3 à 8 heures puis par oxydation atmosphérique à des températures de 260 °C à 400 °C pendant 3 à 6 heures.
