Patent

CA 2431314

An activated carbon-metal oxide matrix is disclosed. The activated carbon- metal oxide matrix may by obtained by a method including the steps of: preoxidizing a carbon material, grinding the preoxidized carbon material; mixing the ground preoxidized material with a metal oxide to form a carbon mixture; extruding the carbon mixture; carbonizing and activating the extrudate. The activated carbon-metal oxide matrix may be used to remove odorous compounds, acidic gases, and volatile organic compounds from a gas.

La présente invention concerne une matrice oxyde métallique-charbons actifs. On peut obtenir cette matrice oxyde métallique-charbons actifs par une technique qui consiste: à préoxyder un matériau de carbone, à pulvériser ce matériau de carbone préoxydé, à mélanger ce matériau préoxydé pulvérisé avec un oxyde métallique de façon à former un mélange de carbone, à extruder ce mélange de carbone, à carboniser et activer ce mélange extrudé. On peut utiliser cette matrice oxyde métallique-charbons actifs pour supprimer des composés odorants, des gaz acides et des composés organiques volatils issus d'un gaz.
