Patent number: 11041128Abstract: A catalyst system has been designed that disrupts the sedimentation process. The catalyst system achieves this by saturating key feed components before the feed components are stripped into their incompatible aromatic cores. The efficacy of this disruptive catalyst system is particularly evident in a hydrocracker configuration that runs in two-stage-recycle operation. The catalyst is a self-supported multi-metallic catalyst prepared from a precursor in the hydroxide form, and the catalyst must be toward the top level of the second stage of the two-stage system.Type: GrantFiled: August 6, 2019Date of Patent: June 22, 2021Assignee: Chevron U.S.A. Inc.Inventors: Theodorus Ludovicus Michael Maesen, Derek Blackwell, Viorel Duma, Varut Komalarajun, Alexander E. Kuperman, Hyunuk Ryu, Horacio Trevino, Alex Yoon, Ujjal Mukherjee

Publication number: 20130212930Abstract: In one aspect, a method for rendering biomass-derived pyrolysis oil miscible with refinery hydrocarbons comprises mixing a high oxygen content bio-oil having an oxygen content of at least about 10 wt. % with a low oxygen content bio-oil having an oxygen content of less than about 8 wt. % to produce a blended oil. The blended oil may be hydrotreated to produce a deoxygenated hydrotreated mixture from which water is removed using a separator, resulting in a low oxygen content hybrid bio-oil intermediate miscible in refinery process streams. A portion of the low oxygen content hybrid bio-oil intermediate may be recycled with the high oxygen content bio-oil or removed for use in a refinery process stream for further hydroprocessing.Type: ApplicationFiled: September 28, 2012Publication date: August 22, 2013Applicant: Chevron USA, Inc.Inventors: Douglas G.
