Abstract

L'invention décrit un perfectionnement permettant d'augmenter la quantité et la qualité des liquides produits, à partir de charbon solide par un procédé comportant une zone de liquéfaction et un réacteur de pyrolyse, de préférence une zone de cokéfaction utilisant des noyaux de coke fluidisés. On recycle les liquides lourds obtenus dans le réacteur de pyrolyse (par exemple les matières de P.E. 538 degrés C) vers la zone de liquéfaction plutôt que vers le réacteur de pyrolyse pour un traitement supplémentaire dans des conditions d'hydrogénation et une transformation des liquides lourds en des liquides à plus faible point d'ébullition, que l'on peut enlever par distillation de l'alimentation du réacteur de pyrolyse. On peut ainsi obtenir divers produits de raffinage.The invention describes an improvement making it possible to increase the quantity and the quality of the liquids produced, from solid coal by a process comprising a liquefaction zone and a pyrolysis reactor, preferably a coking zone using fluidized coke cores. . Heavy liquids obtained in the pyrolysis reactor (e.g. PE 538 degrees C material) are recycled to the liquefaction zone rather than to the pyrolysis reactor for further processing under hydrogenation conditions and heavy liquid processing to lower boiling liquids, which can be distilled off from the feed to the pyrolysis reactor. Various refining products can thus be obtained.
