  • Publication number: 20110039955
    Abstract: This invention describes gas-solid, liquid-solid and gas-solid-liquid processes in microchannels devices including such processes as heterogeneous catalysis, particle formation, particle attrition, particle separation and adsorption or desorption of selected species. Various processes can be enhanced by the unique properties of microchannels such as the predominance of laminar flow, high rates of shear, high rates of heat transfer and high rates of mass transfer. Also encompassed by this invention are methods for the introduction to and removal from microchannels of particle containing fluid streams.

  • Patent number: 7883670
    Abstract: New designs, methods and processes are described that in which laminated devices and configured in a style named the “ortho” style. To form a device in the ortho style, plates or sheets are machined to have apertures and then stacked together such that the apertures connect and fluid can flow through the device in a direction that is substantially parallel to the direction of sheet thickness. Various laminated devices and processes using them are also described. For example, devices in which non-rectangular microchannels conform around reaction chambers or other bodies that need to be heated or cooled, are described. Features that separate or trip boundary layer and enhance heat transfer are also described.
