Abstract
Procédé de craquage thermique de fractions lourdes d'huiles de pétrole. On utilise, en tant que système réactionnel, une pluralité de récipients 4, 5 et 6 disposés en série, dont les températures internes sont graduellement abaissées à chaque étape d'une valeur fixée, dans la direction du transfert de la charge Les brais résiduels obtenus sont riches en matières aromatiques, homogènes et sont moins sensibles à la cokéfaction.Process for thermal cracking of heavy fractions of petroleum oils. As the reaction system, a plurality of vessels 4, 5 and 6 arranged in series are used, the internal temperatures of which are gradually lowered at each stage by a fixed value, in the direction of the transfer of the charge The residual pitches obtained are rich in aromatics, homogeneous and are less sensitive to coking.
