    Abstract: A hydroprocessing catalyst has been developed. The catalyst is a crystalline transition metal tungstate material or metal sulfides derived therefrom, or both. The hydroprocessing using the crystalline transition metal tungstate material may include hydrodenitrification, hydrodesulfurization, hydrodemetallation, hydrodesilication, hydrodearomatization, hydroisomerization, hydrotreating, hydrofining, and hydrocracking. A data system comprising at least one processor; at least one memory storing computer-executable instructions; and at least one receiver configured to receive data of at least one unit or stream in fluid communication with and downstream from or upstream to a conversion process comprising at least one reaction catalyzed by the catalyst or a metal sulfide decomposition product of the catalyst has been developed.

    Abstract: Devices and methods for managing the state of health of an electrolyte in redox flow batteries (RFB) efficiently are described. A diffusion cell is added to the RFB which controls one or more properties of the electrolytes using the diffusion of protons through a proton exchange membrane. The diffusion cell can resemble an electrochemical cell in that there are two fluid chambers divided by a proton conducting membrane. Anolyte flows through one side of the device where it contacts the proton conducting membrane, and catholyte flows through the second side of the device where it contacts the other face of the proton conducting membrane. The concentration gradient of protons from high concentration in the catholyte to low concentration in the anolyte is the driving force for proton diffusion, rather than electromotive force, which greatly simplifies the design and operation.

    Abstract: Various current collectors for redox flow batteries are described. The current collectors include at least one metal plate encapsulated in a conductive polymer end plate, the metal plate to the back of a stack end plate with a conductive adhesive, and a flat metal plate having deformable tabs. Battery flow systems incorporating the current collectors are also described. Battery flow systems with easily replaceable current collectors are also described.

    Abstract: A protective layer for an electrolyte in a flow battery and an electrolyte tank having a protective layer. The protective layer includes a light oil that includes hydrophobic hydrocarbons. The light oil having a density lower than a density of the electrolyte, the hydrophobic hydrocarbons being non-reactive to the electrolyte. The protective layer may be a liquid layer or may include a substrate impregnated with the light oil. An inert gas may also be utilized in the electrolyte tank.

    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.
