Abstract
L'invention concerne un procédé consistant à utiliser un bioréacteur doté d'un absorbeur à pulvérisation pour le traitement biocatalytique de gaz. Le procédé décrit dans cette invention comprend les étapes qui consistent à mettre en contact une phase gazeuse, qui contient un gaz devant être traité, avec une phase liquide contenant un réactif capable de réagir chimiquement avec le gaz et/ou d'absorber le gaz, ce qui permet de produire une phase liquide résiduaire contenant au moins un produit de réaction et une phase gazeuse traitée essentiellement exempte de gaz; une telle étape étant réalisée en présence de biocatalyseurs permettant de catalyser la réaction chimique entre le gaz et le réactif. Dans ce procédé, la phase gazeuse est mise en contact avec des gouttelettes pulvérisées des biocatalyseurs contenant la phase liquide. L'utilisation de ces gouttelettes permet d'augmenter l'interface entre le gaz et le liquide, ce qui favorise un taux de transfert de masse élevé du gaz devant être traité depuis la phase gazeuse vers la phase liquide. Ces conditions de transfert de masse élevé permettent de transformer le gaz avec une vitesse de réaction maximum. Le procédé susmentionné peut être avantageusement utilisé pour nettoyer ou purifier une phase gazeuse contenant un gaz dangereux. Par exemple, le procédé peut être utilisé pour extraire du CO¿2? d'une émission de gaz.
