Abstract: A fuel cell is provided including an anode configured to receive, and allow to pass through, an anode process gas, a cathode configured to receive, and allow to pass through, a cathode process gas, and an electrolyte matrix layer separating the anode and the cathode. One of the anode or the cathode has an extended edge seal chamber, and the fuel cell is configured to receive the anode process gas and the cathode process gas in substantially perpendicular directions relative to each other, and the extended edge seal chamber is configured to allow the anode process gas and the cathode process gas to pass through the anode and the cathode in substantially parallel flow paths.

Abstract: A submersible device submersible within an algae slurry contained within a pond of an algae bioreactor, the submersible device including a drive motor operable to actuate one or more driven devices that move the submersible device within the pond, a circulation device operable to circulate the algae slurry through the submersible device and discharge the algae slurry back into the pond from a discharge port provided on the submersible device, and a computer system that controls operation of the drive motor and the circulation device.

Abstract: A system for growing algae in a slurry, includes a pond having an inlet and an outlet and a plurality of contiguous elongate channel segments coupled fluidically in sequence between the inlet and the outlet, and the inlet is located at an elevation higher than outlet to allow gravity to flow the slurry from the inlet to the outlet. The system further includes a separation device fluidically coupled to the outlet to receive and separate algae from the slurry.

Abstract: Disclosed are processes and systems for oxidizing cycloalkylbenzene such as cyclohexylbenzene to make an oxygenate such as a hydroperoxide thereof. A liquid distributor having multiple liquid ingress ports is used for supplying a cycloalkylbenzene-containing liquid into an oxidation reactor in the form of liquid streams forming part of the reaction medium. A gas distributor distributing an O2-containing gas into the reaction medium in the form of gas streams is preferably located below the liquid distributor. Preferably the gas bubbles upwards in the reaction medium. The agitation and mixing provided by the liquid streams, gas streams/bubbles result in sufficient homogeneity of cycloalkylbenzene concentration, cycloalkylbenzene hydroperoxide concentration, dissolved oxygen concentration, and temperature in the liquid phase.

Abstract: Systems, methods, and apparatus for distribution of oxygen-containing gas within a gas-liquid oxidation reaction are provided herein. The invention is particularly suited for oxidation of liquid-phase organic reactants with oxidizing gas, such as the oxidation of cyclohexylbenzene to cyclohexylbenzene hydroperoxide using an oxygen-containing gas. The oxygen-containing gas is distributed through a gas distributor and into a liquid-phase reaction medium within an oxidation reactor. In some aspects, this achieves a high degree of uniformity of oxygen concentration within the liquid-phase reaction medium. The gas distributor is disposed within a lower portion of the reactor, and may comprise a network of conduits in fluid communication with each other, which are arranged within a plane that is substantially parallel to a bottom surface of the reactor.
