Patent number: 11865515Abstract: An active material useful in an oxidative dehydrogenation reactor system has an active phase, and a mixed metal oxide support phase. The active phase includes a transition metal oxide such as manganese oxide, which is reversibly oxidizable and/or reducible between oxidized and reduced states. The support phase includes a mixed metal oxide of a two or more IUPAC Group 2-14 elements. The active phase can also include a promoter such as Na-WO4 and/or a selectivity modifier such as Al or ceria. Also, a reactor including the active material in a reactor, a method of making the active material, and a method of using the active material in a regenerative reaction process.Type: GrantFiled: December 6, 2021Date of Patent: January 9, 2024Assignee: EXXONMOBIL TECHNOLOGY AND ENGINEERING COMPANYInventors: Brian M.

Patent number: 11773335Abstract: Systems and methods are provided for using a reverse flow reactor (or another reactor with flows in opposing directions at different parts of a process cycle) for pyrolysis of hydrocarbons. The systems and methods can include a reactor that includes a combustion catalyst to initiate and/or maintain combustion within the reactor in a controlled manner during the heating and/or regeneration portion(s) of the reaction cycle. A fuel can also be used that has a greater resistance to auto-combustion, such as a fuel that is composed primarily of methane and/or other hydrocarbons. During operation, the temperature in at least an initial portion of the reactor can be maintained at a temperature so that auto-ignition of the auto-combustion resistant fuel injected during the heating step(s) is reduced or minimized. This can allow combustion to be initiated when the auto-combustion resistant fuel comes into contact with the catalyst.Type: GrantFiled: December 7, 2021Date of Patent: October 3, 2023Assignee: EXXONMOBIL TECHNOLOGY AND ENGINEERING COMPANYInventors: Brian M. Weiss, Sophie Liu, Michael R. Harper, Jr., Herbert W. Barry, Changmin Chun, Barrington S. Goldson, Justin R. Johnson, Faria Nusrat

Patent number: 11465903Abstract: Systems and methods are provided for using oxycombustion to provide heat within a reverse flow reactor environment. The oxygen for the oxycombustion can be provided by oxygen stored in an oxygen storage component in the reactor. By using an oxygen storage component to provide the oxygen for combustion during the regeneration step, heat can be added to a reverse flow reactor while reducing or minimizing addition of diluents and while avoiding the need for an air separation unit. As a result, a regeneration flue gas can be formed that is substantially composed of CO2 and/or H2O without requiring the additional cost of creating a substantially pure oxygen-containing gas flow.Type: GrantFiled: April 2, 2020Date of Patent: October 11, 2022Assignee: ExxonMobil Technology and Engineering CompanyInventors: Everett J. O'Neal, Brian M. Weiss, Anastasios I. Skoulidas

Publication number: 20220274085Abstract: A reverse flow reactor (RFR) and process having a forward reaction feed cycle, a reverse reaction feed cycle, and a reverse regeneration cycle. The heat convected in the forward feed cycle matches the heat convected in the reverse flow cycles. Compared to an RFR without the reverse feed cycle, the three-cycle RPR substantially reduces the regeneration air flow rate, associated compression requirements, and the overall reactor volume, that are required.Type: ApplicationFiled: July 30, 2020Publication date: September 1, 2022Inventors: Brian M. Weiss, Changmin Chun, Sophie Liu, Federico Barrai, Paul F. Keusenkothen, Zachary D. Young
