Patent number: 11021420Abstract: Improvements in the commercial viability of oxygen transfer agents (OTAs) and/or catalysts associated with the OCM and the ODH of hydrocarbons to olefins through enhancement of one or more of the selectivity, yield, rate and lifetime of the OTA and/or catalyst is described by one or more of (i) exposing the OTA or the catalyst to a sulfur-containing compound at a site or at a time that is different from where and when the saturated hydrocarbon is converted by the OTA or the catalyst to an unsaturated hydrocarbon; (ii) increasing the particle density of the OTA or the catalyst by treating the OTA or the catalyst with a reducing agent at a site different from where the saturated hydrocarbon is converted by the OTA or by the catalyst to an unsaturated hydrocarbon; and (iii) removing non-selective redox oxygen (NSRO) present on the OTA by subjecting the OTA to a gas that is substantially free of any molecular oxygen.Type: GrantFiled: April 30, 2020Date of Patent: June 1, 2021Assignee: Bio2Electric, LLCInventor: John A.

Patent number: 10322392Abstract: A system for promoting endothermic conversions includes a first and a second portion, a first and second supply, a first outlet and a heat exchanger. The first portion defines a first inner volume containing an oxygen transfer agent. The first supply contains one or more of hydrogen and a saturated hydrocarbon and is fluidly connected to the first inner volume. The first outlet conveys one or more of carbon dioxide, water, and an unsaturated hydrocarbon from the first inner volume. The second portion and the heat exchanger positioned within the second portion define a second inner volume containing reduced oxygen transfer agent. The second supply contains an oxidizing agent fluidly connected to the second inner volume. The heat exchanger also defines a third inner volume segregated from the second inner volume, and the heat exchanger is configured to transfer heat resulting from the oxidation of the reduced oxygen transfer agent to the third inner volume.Type: GrantFiled: June 21, 2016Date of Patent: June 18, 2019Assignee: Bio2Electric, LLCInventor: John A. Sofranko

Patent number: 10138182Abstract: A oxygen transfer agent useful for the oxidative dehydrogenation of saturated hydrocarbons includes at least one mixed oxide derived from manganese or compounds thereof, as well as a promoter, such as tungsten and/or phosphorus. The oxygen transfer agent may also include an alkali metal or compounds thereof, boron or compounds thereof, an oxide of an alkaline earth metal, and an oxide containing one or more of one or more of manganese, lithium, boron, and magnesium. A reactor is at least partially filled with the oxygen transfer agent in the form of a fixed or circulating bed and provides an unsaturated hydrocarbon product, such as ethylene and/or propylene. The oxygen transfer agent may be regenerated using oxygen.Type: GrantFiled: September 23, 2015Date of Patent: November 27, 2018Assignees: Bio2Electric, LLC, North Carolina State UniversityInventors: John A. Sofranko, Fanxing Li, Luke Neal

Publication number: 20170247803Abstract: A reactor and process capable of concurrently producing electric power and selectively oxidizing gaseous components in a feed stream, such as hydrocarbons to unsaturated products, which are useful intermediates in the production of liquid fuels. The reactor includes an oxidation membrane, a reduction membrane, an electron barrier, and a conductor. The oxidation membrane and reduction membrane include an MIEC oxide. The electron barrier, located between the oxidation membrane and the reduction membrane, is configured to allow transmission of oxygen anions from the reduction membrane to the oxidation membrane and resist transmission of electrons from the oxidation membrane to the reduction membrane. The conductor conducts electrons from the oxidation membrane to the reduction membrane.Type: ApplicationFiled: April 6, 2017Publication date: August 31, 2017Applicant: Bio2Electric, LLCInventor: John A.
