Patent number: 10668463Abstract: 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.Type: GrantFiled: April 25, 2018Date of Patent: June 2, 2020Assignee: ExxonMobil Research and Engineering CompanyInventors: Chuansheng Bai, Paul Podsiadlo, Stephen J. McCarthy, Kiara M Benitez
