Abstract (en)

[origin: WO8203403A1] After having prepared the coke paste by one or a plurality of the following operations: grinding (1), drying (2), preheating (3) and addition of a binder-solvent (4), the coke paste is given the selected form by compacting (5), and then preferably a surface burning (6) is effected, followed by a coking (7) under a gas pressure substantially higher than the atmospheric pressure, by means of distillation gases which are preferably recycled and pulsed through the aggregate bed and of which the temperature and the pressure are kept at appropriate predetermined values. The coke obtained is then quenched (8).

Abstract (fr)

Apres avoir prepare la pate a coke par une ou plusieurs des operations suivantes: broyage (1), sechage (2), prechauffage (3) et addition d'un liant-solvant (4), on lui donne la forme choisie, par compactage (5), puis on assure de preference une cuisson superficielle (6), on la soumet a une cokefaction (7) sous une pression gazeuse sensiblement superieure a la pression atmospherique, au moyen des gaz de distillation qui sont de preference recycles et pulses a travers le lit d'agregats et dont la temperature et la pression sont maintenues a des valeurs adequates predeterminees. Le coke obtenu est ensuite eteint (8).
