Abstract

L'invention concerne un procédé permettant non seulement de pyrolyser un déchet contenant de la matière organique en l'absence d'oxygène, mais également d'effectuer un traitement continu pendant le fonctionnement normal, tout en évitant une fuite et/ou un écoulement à contre-courant du gaz de pyrolysat résultant de la pyrolyse. Le procédé selon l'invention permet de pyrolyser en continu un déchet contenant de la matière organique et ainsi générer un gaz de pyrolysat et un carbure résiduel. Ledit déchet contenant de la matière organique chargé côté amont est pyrolysé et le gaz de pyrolysat produit est émis côté aval ; un gaz inerte est introduit, via un moyen d'injection de gaz inerte, dans une chambre hermétiquement fermée fournissant une zone de chauffage pyrolytique entre le côté amont et le côté aval dans laquelle est émis ledit carbure résiduel, le gaz inerte étant introduit de sorte que la pression de gaz inerte à l'intérieur de ladite chambre soit constamment supérieure à la pression atmosphérique ; l'air ambiant est coupé de manière à placer la chambre hermétiquement fermée dans des conditions anoxiques ; enfin, tandis que l'on crée un gradient de pression de gaz inerte entre le côté amont et le côté aval de ladite chambre de manière à dépasser la pression du gaz de pyrolysat généré, ledit gaz de pyrolysat est émis par la chambre hermétiquement fermée sans remonter à contre-courant du côté aval vers le côté amont.
