Abstract

L'invention porte sur un procédé de séparation de gaz consistant à mettre un gaz sélectionné présent dans un courant d'un mélange de gaz en contact avec une enzyme présentant un site actif directement en contact avec le courant gazeux ce qui permet d'en extraire au moins une partie du gaz sélectionné. Dans un mode de réalisation, le gaz sélectionné est mis en contact avec une enzyme solvatée dont le site actif est directement en contact avec la phase gazeuse, le gaz sélectionné se trouvant converti en un premier produit en phase condensée par contact avec l'enzyme solvatée. L'invention porte également sur un bioréacteur comportant une cuve présentant au moins une première paroi délimitant une zone d'admission et une deuxième paroi délimitant une deuxième zone de phase. Une partie de la deuxième cloison est perméable à au moins l'un des gaz sélectionnés de la zone d'admission, mais retient la deuxième phase dans la zone de deuxième phase. Une partie de la deuxième cloison comporte également une surface support à laquelle est fixée au moins une enzyme si bien que le mélange de gaz pénétrant dans la zone d'admission entre en contact avec l'enzyme qui extrait un gaz sélectionné du mélange de gaz et transfert le gaz sélectionné dans la zone de seconde phase. L'invention porte en outre sur un autre bioréacteur comportant: des perles flottantes revêtues d'un enzyme flottant à la surface d'une phase fluide condensée et en contact avec une phase gazeuse de manière à ce que le site actif de l'enzyme soit en contact direct avec la phase gazeuse, les perles pouvant tourner librement en réponse aux mouvements de l'une ou l'autre phase. L'invention porte enfin sur un moyen mettant en mouvement au moins l'une des phases de manière à ce que des parties des perles entrent alternativement en contact avec la phase gazeuse et avec la phase fluide, ce qui amène le gaz sélectionné en phase fluide condensée.
