Title (EN) SLURRY HYDROCARBON SYNTHESIS WITH CYCLIC CO PURGE AND CATALYST REJUVENATION
(FR) SYNTHESE DE BOUES D'HYDROCARBURES A PURGE CYCLIQUE DU CO ET REGENERATION DU CATALYSEUR
Abstract:
(EN) Partially deactivated catalyst in a slurry hydrocarbon synthesis process is rejuvenated employing a cyclic rejuvenation process in which syngas or CO flow into the slurry is stopped to stop the hydrocarbon synthesis reaction, the CO purged out of the slurry with a purge gas in the presence of hydrogen, the catalyst rejuvenated with a hydrogen containing rejuvenating gas and the hydrocarbon synthesis reaction restarted by passing the synthesis gas feed back into the reactor. All or a portion of the purge gas and/or the rejuvenating gas may be recycled during the respective purge and/or rejuvenation. The hydrogen required during the purge is typically part of the purge gas.
(FR) Dans un processus de synthèse de boues d'hydrocarbures, on régénère le catalyseur partiellement désactivé au moyen d'un procédé cyclique de régénération selon lequel: le courant de gaz de synthèse ou de CO traversant les boues est arrêté afin d'interrompre la réaction de synthèse, le CO est retiré des boues à l'aide d'un gaz épurateur en présence d'hydrogène, le catalyseur est régénéré à l'aide d'un gaz régénérateur contenant de l'hydrogène, et la réaction relancée en faisant repasser le gaz de synthèse dans le réacteur. Tout ou partie du gaz épurateur et/ou du gaz régénérateur peut être recyclé pendant les opérations d'épuration et de régénération. L'hydrogène requis pour l'épuration fait normalement partie du gaz d'épuration.
