Title (EN) A METHOD OF RECOVERING HIGH-GRADE FUEL FROM SOLID MINERAL-FUEL RAW MATERIAL
(FR) PROCEDE DE RECUPERATION DE COMBUSTIBLE DE HAUTE QUALITE A PARTIR D"UN MATERIAU BRUT DE COMBUSTIBLE MINERAL SOLIDE
Abstract: front page image
(EN)A method for recovering high-grade, preferably sulphur-free fuel from bituminous or pyrobituminous mineral-fuel materials, such as coal, oil shale and alum shale, said method comprising finely-dividing the raw material and dividing said material into at least one fuel concentrate and a residual product which is bound to a durable agglomerate form by means of a binder. The method is characterized in that the raw material, subsequent to finely-dividing the same to a sufficient particle size physically, is divided into a high-grade, preferably sulphur-free fuel concentrate containing a given quantity of ash-forming minerals adjusted relative to the content of ash-forming minerals of the raw material, and into a residual product comprising substantial ash-forming minerals. A binder for hydraulically binding the residual product to a durable agglomerate is produced from the fuel concentrate by combusting the same while using the fuel content of said concentrate.
(FR)Procede de recuperation d"un combustible de haute qualite, de preference exempt de soufre, a partir de materiaux combustibles solides bitumeux ou pyro-bitumineux, tels que des schistes huileux ou alumineux, ledit procede comprenant la fine division du materiau brut et en separant ce materiau en au moins un concentrat de combustible et un produit residuel qui est lie au moyen d"un liant sous une forme d"agregat durable. Le procede est caracterise en ce que le materiau brut apres sa reduction physique en fines particules de taille suffisante est separe en un concentrat de combustible de haute qualite, de preference exempt de soufre, contenant une quantite donnee de mineraux formant des cendres ajustee par rapport au contenu en mineraux formant des cendres du materiau brut et en un produit residuel comprenant essentiellement des mineraux formant les cendres. Un liant pour la liaison hydraulique du produit residuel en un agglomerat durable est obtenu a partir du concentrat de combustible en le faisant bruler tout en utilisant le contenu en combustible dudit concentrat.
