description L'INVENTION CONCERNE UN PROCEDE POUR EXTRAIRE LES HYDROCARBURES D'UN SUBSTRAT CONTENANT DES HYDROCARBURES ET UN APPAREIL UTILISABLE POUR LA MISE EN OEUVRE DE CE PROCEDE.ON EFFECTUE L'EXTRACTION EN L'ABSENCE QUASI-COMPLETE D'OXYGENE, A DES TEMPERATURES DE PLUS DE 400C, EN FAISANT PASSER DES PARTICULES DU SUBSTRAT A TRAVERS UNE MULTIPLICITE DE ZONES SUCCESSIVES 31 A 35 DANS LESQUELLES LE SUBSTRAT EST MELANGE AVEC UN MILIEU SOLIDE PORTEUR DE CHALEUR, LE MELANGE ETANT MAINTENU DANS UN ETAT DE LIT FLUIDISE, ET LES HYDROCARBURES LIBERES ETANT EVACUES PAR PASSAGE D'UN GAZ INERTE DE STRIPPAGE EN ECOULEMENT TRANSVERSAL PAR RAPPORT AU PASSAGE DES PARTICULES DU SUBSTRAT.APPLICATION NOTAMMENT AU TRAITEMENT DU SCHISTE BITUMINEUX. Hydrocarbons are extracted from a hydrocarbon-bearing substrate, e.g. shale oil, bituminous coal, tar sand, in the substantial absence of oxygen at temperatures above 400 DEG C., by passing substrate particles through a plurality of successive stages in which the substrate is mixed with a solid heat-bearing medium, the mixture being maintained in a fluidized-bed condition, and the liberated hydrocarbons being removed by passage of an inert stripping gas in cross-current flow with respect to the passage of the substrate particles. The average cross-sectional area of at least one or more of the stages subsequent to the first one is preferably smaller than the average cross-sectional area of one or more of the preceding stages. An apparatus for carrying out the process is described.
