  • Publication number: 20230097875
    Abstract: A flow battery system with a cathode cell including a first electrode, an anode cell includes a second electrode, and a membrane between the two cells. A first electrolyte tank includes a catholyte. A second electrolyte tank includes an anolyte. The system includes two rebalancing cells. A first rebalancing cell is in fluid communication between the cathode cell and the first electrolyte tank and is configured to reduce active species from the catholyte. The second rebalancing cell is in fluid communication with the first electrolyte tank and the second electrolyte tank such that the first electrolyte tank and the second electrolyte tank are in direct fluid communication. The second rebalancing cell is configured to reduce active species from the catholyte and the reduced catholyte may be combined directly with the anolyte. The second rebalancing cell may be a chemical reactor, a catalytic reactor, or an electrochemical reactor.

  • Patent number: 10941352
    Abstract: Processes for producing a gasoline blend in which C7 hydrocarbons are separated from a naphtha feed. The C7 hydrocarbons are isomerized and dehydrogenated to increase the octane value of the components therein. In order to avoid conversion of methylcyclohexane to toluene in the dehydrogenation reactor, the various processes provide flow schemes in which the methylcyclohexane bypasses the C7 dehydrogenation reaction zone.

  • Patent number: 10626065
    Abstract: Processes for co-production of methyl tertiary-butyl ether (MTBE) and alkylate is disclosed. The process includes comprising passing a hydrocarbon feed stream comprising C4 hydrocarbons to a dehydrogenation unit to generate a dehydrogenation effluent comprising C4 olefins. The dehydrogenation effluent is passed to a MTBE unit to provide a mixed stream comprising C4 olefins and MTBE. The mixed stream is separated to provide an MTBE product stream and a fractionator overhead stream comprising olefins. The fractionator overhead stream is passed to an alkylation unit to produce an alkylation product stream comprising an alkylate.

  • Patent number: 10384986
    Abstract: A process is presented for the production of light olefins. The process utilizes a SAPO-18 catalyst and is operated at an elevated pressure. The process generates higher concentrations of heavier olefins which can then be processed to generate light olefins. The processing of the heavier olefins can include metathesis reactions and olefin cracking processes.
