  • Publication number: 20150101406
    Abstract: In various aspects, methods and systems are provided for monitoring catalyst bed levels using multiple sensors that are temporarily installed in a reactor during catalyst loading. The multiple sensors are able to take distance measurements at substantially the same time and at predetermined time intervals so as to provide a catalyst time profile. The catalyst time profile allows an operator monitor catalyst levels during and after catalyst loading. Once catalyst loading is completed, the multiple sensors are removed from the reactor.

    Abstract: A method for producing a hydrogen containing gas for use in an internal combustion engine system is provided. The method includes cyclically operating at least two pressure swing reformer reactors such that one is reforming while another is regenerating, thereby producing a continuous stream of hydrogen containing gas. During engine operation exhaust gas is fed to the pressure swing reformer reactor that is undergoing regeneration, thereby supplying at least part of the heat for regeneration. Also, the hydrogen gas produced is used in at least one of (i) the engine; (ii) an engine exhaust treatment device; and (iii) a fuel cell.

  • Patent number: 6102843
    Abstract: A one-pass centrifuge separator for mixtures of two liquids which may also contain gas. The centrifuge uses separation zones on a rotor's inner wall to improve separation efficiency and minimize turbulent mixing. The zones consist of surface and interface vanes, and baffle plates to control flow at the fluid interface. The zones also retain an open concept to facilitate washing by cleaning fluids which are provided by nozzles installed on a stationary feedpipe mounted along the rotational axis of the centrifuge. A fluid accelerator gradually accelerates the fluid from the feedpipe to the inner wall of the rotor.
