The present invention discloses a process for distillation and decarbonization of oil shale species using fluidized bed. The shale oil contained in oil shale having certain size distribution in fluidizing condition is gasified by using high temperature dry gas and/or high temperature steam as heat carrier and fluidizing medium, meanwhile, dry gas dissolves some organics in oil shale, that is, fluidizing, distillation and deoil. The powder which has removed shale oil is fluidized by high temperature air under oxygen riched condition. The carbon in oil shale is combusted, ie. fluidizing decabonization.
Le schiste bitumeux contenu dans le schiste bitumeux présentant une certaine distribution granulométrie en condition fluidisée est gazéifié au moyen d'un gaz sec à température élevée et/ou d'une vapeur à température élevée en tant que véhicule thermique et milieu de fluidisation, alors que le gaz sec dissout certains éléments organiques dans le schiste bitumeux, à savoir les fluidise, les distille et les déshuile. La poudre qui a éliminé le schiste bitumeux est fluidisée par de l'air à température élevée dans des conditions riches en oxygène. Le carbone contenu dans le schiste bitumeux est brûlé, à savoir décarbonisé par fluidisation.
