Abstract

L'invention concerne un procédé de préparation de différents brais. Elle se rapporte à un procédé qui comprend le craquage thermique adiabatique d'une huile initiale formée de fractions d'huile obtenues par traitement de bruts en vue du retrait d'impuretés ou de bruts ayant des quantités suffisamment faibles d'impuretés, dans un réacteur de craquage adiabatique, à une température de 700 à 1000 degrés C, le réglage de la teneur en brai entre 20 et 80 % en poids, le traitement thermique du brai brut obtenu dans un réhauffeur à une température de 450 à 550 degrés C et une pression de 50 à 150 bars, pendant 1 à 15 min, puis le traitement dans un maturateur à une température d'environ 350 à 450 degrés C, à une pression d'environ 0,5 à 10 bars et pendant un temps de 15 min à 10 h. Application à la préparation de brais pour électrodes de fours à arc électrique.The invention relates to a method for preparing different pitches. It relates to a process which comprises the adiabatic thermal cracking of an initial oil formed from oil fractions obtained by treating crudes with a view to removing impurities or crudes having sufficiently low quantities of impurities, in a reactor. adiabatic cracking, at a temperature of 700 to 1000 degrees C, adjusting the pitch content between 20 and 80% by weight, heat treatment of the raw pitch obtained in a reheater at a temperature of 450 to 550 degrees C and a pressure of 50 to 150 bars, for 1 to 15 min, then the treatment in a maturer at a temperature of about 350 to 450 degrees C, at a pressure of about 0.5 to 10 bars and for a time of 15 min at 10 o 'clock. Application to the preparation of pitches for electrodes of electric arc furnaces.
