Title (EN) METHODS FOR REGENERATING AND REJUVENATING CATALYSTS
(FR) PROCÉDÉS DE RÉGÉNÉRATION ET DE RAJEUNISSEMENT DE CATALYSEURS
Abstract:
(EN) Methods for regenerating and/or rejuvenating catalysts, particularly dewaxing catalysts, as well as methods for performing dewaxing of diesel or distillate boiling range feeds with the regenerated and/or rejuvenated catalyst are provided herein. The regeneration and/or rejuvenation methods can include calcining spent catalyst followed by contacting the calcined catalyst with a solution comprising a complexing agent, which can restore hydrotreatment (HDT) activity and dewaxing activity of the spent catalyst such that it may be reused during hydroprocessing.
(FR) L'invention concerne des procédés de régénération et/ou de rajeunissement de catalyseurs, en particulier de catalyseurs de déparaffinage, ainsi que des procédés de déparaffinage de charges de diesel ou de plage d'ébullition de distillat avec le catalyseur régénéré et/ou rajeuni. Les procédés de régénération et/ou de rajeunissement peuvent comprendre la calcination du catalyseur usé puis la mise en contact du catalyseur calciné avec une solution comprenant un agent complexant, ce qui permet de restaurer l'activité d'hydrotraitement (HDT) et l'activité de déparaffinage du catalyseur usé de telle sorte qu'il peut être réutilisé pendant l'hydrotraitement.
