The device and method of the present invention employs a column (1) having a gas inlet (2) in its lower part (5) and a gas outlet (3) in its upper part (4). Carbon particles are introduced into the column (1) through a supply pipe (7). The supply pipe (7) is movable so that by manipulating the height of the supply pipe (7) in conjunction with discharging particulate matter through the column (1), the height of the bed (8) of particulate matter in the column (1) can be adjusted so that the retention time of the off gas in the particulate bed (8) is constant. By maintaining a constant retention time of the off gas in the bed (8), complete conversion of the off gas is achieved.
L'invention concerne un dispositif et un procédé faisant appel à une colonne (1) comprenant une entrée (2) de gaz dans sa partie inférieure (5) et une sortie (3) de gaz dans sa partie supérieure (4). Des particules de carbone sont introduites dans la colonne (1) à travers un conduit d'alimentation (7). Le conduit d'alimentation (7) est mobile de telle sorte que la manipulation de la hauteur du conduit (7) d'alimentation conjointement à la décharge du matériau en particules à travers la colonne (1) permet de régler la hauteur du lit (8) de matériau en particules dans la colonne (1) afin d'assurer un temps de rétention constant des gaz d'échappement dans le lit (8) de particules. Le maintien d'un temps de rétention constant des gaz d'échappement permet d'obtenir une conversion complète de ces derniers.
