  • Patent number: 8153059
    Abstract: A chip-holder for holding a micro-fluidic chip has a fixer for detachably fixing the micro-fluidic chip in the chip-holder and at least one process control device configured to support control or monitoring of a chemical process in the micro-fluidic chip, wherein the chip-holder is configured such that the process control device and the micro-fluidic chip are directly and detachably coupled when the micro-fluidic chip is fixed in the chip-holder. Such a chip-holder brings along the advantage that the micro-fluidic chip can easily be removed and exchanged while the process control device can be reused. This reduces running costs of a chemical microreactor system drastically and allows for a very flexible usage of a chemical microreactor system.
    Type: Grant
    Filed: July 25, 2005
    Date of Patent: April 10, 2012
    Assignee: Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung e.V.
    Inventors: Hoc Khiem Trieu, Michael Bollerott, Martin Kemmerling, Robert Hildebrand, Jan Van Hest, Kaspar Koch, Pieter Nieuwland, Teris A. Van Beek, Ernst J. R. Sudhölter, Remko M. Boom, Anja E. M. Janssen, Floris Rutjes

  • Patent number: 4640766
    Abstract: C.sub.4.sup.- hydrocarbons are converted into syngas with a H.sub.2 /CO molar ratio between 0.25 and 2.25 by reforming at a pressure above 10 bar in the presence of specified amounts of carbon dioxide and steam followed by conversion of the syngas into C.sub.5.sup.+ hydrocarbons over a cobalt-containing catalyst or a catalyst combination comprising a cobalt-containing catalyst and having CO-shift activity.

    Date of Patent: February 3, 1987
    Assignee: Shell Oil Company
    Inventors: Martin F. M. Post, Swan T. Sie, Ernst J. R. Sudholter
  • Patent number: 4628133
    Abstract: A two-step process is disclosed wherein C.sub.9.sup.+ hydrocarbons are prepared from C.sub.4.sup.- hydrocarbons by steam reforming followed by Fischer-Tropsch synthesis over a special cobalt-containing catalyst. Yields of C.sub.9.sup.+ hydrocarbons are increased by recycling a gaseous fraction comprising unconverted H.sub.2 and CO as well as C.sub.8.sup.- hydrocarbon by-products and steam to the steam reformer.

  • Patent number: 4579985
    Abstract: C.sub.5.sup.+ hydrocarbons are prepared from C.sub.4.sup.- hydrocarbons by a two-stage process comprising steam reforming followed by Fischer-Tropsch synthesis over a special cobalt-containing catalyst; a gaseous fraction comprising unconverted H.sub.2 and CO as well as C.sub.4.sup.- hydrocarbons and CO.sub.2 formed as by-products is separated from the synthesized product and recycled to the steam reformer.
