The present invention is concerned with upgrading the BTU values of carbonaceous materials. The carbonaceous material is introduced into a heat exchanger (20) and is injected with gas such as an inert gas or carbon dioxide at a high pressure to raise the pressure at which the upgrading process is carried out. The carbonaceous material is then heated to the desired temperature by circulating a heat exchange medium throughout the outer casing (30). Water and other by-products such as tar and gases are recovered during this process. The heated water may be used as a source of pre-heating feed material in another vessel.
La présente invention concerne l'amélioration des valeurs BTU de matériaux carbonés. Le matériau carboné est introduit dans un échangeur de chaleur (20) et on lui injecte un gaz tel qu'un gaz inerte ou dioxyde de carbone à une pression élevée afin de relever la pression à laquelle on doit exécuter ledit processus. Ensuite on chauffe le matériau carboné à la température désirée en faisant circuler un milieu caloporteur dans l'enveloppe externe (30). Lors de l'exécution du processus, on récupère l'eau et d'autres sous-produits tels que du goudron et des gaz. L'eau chauffée peut être utilisée comme source de matériau d'alimentation de préchauffage dans une autre cuve.
