  • Patent number: 8784949
    Abstract: The present invention relates to a novel process for the remote plasma surface treatment of substrate particles at atmospheric pressure. The invention is motivated by the urge to overcome major drawbacks of particle treatment in low pressure plasmas and in-situ particle treatment at atmospheric pressure. The former requires complex and mostly expensive vacuum installations and vacuum locks usually prohibiting continuous processing. Independent of the system pressure, in-situ plasma treatment causes particle charging and therefore undesirable interaction with the electric field of the discharge, which is seen to contribute to the process of reactor clogging. Additionally, the filamentary discharges modes of atmospheric pressure plasmas are inflicted with inhomogeneous surface treatment. Furthermore, short radical lifetimes at elevated pressures complicate a remote plasma treatment approach as widely used in low pressure applications.

  • Publication number: 20120315390
    Abstract: Apparatus and methods are described for transporting and cooling silicon-coated granules produced in a fluidized bed reactor. The described system allows consistent silicon-coated granule production with fewer impurities than traditional silicon granule coolers. Granules flow from the reactor into a cooling vessel and subsequently are transported to a post production treatment system below the cooler. The cooling vessel is constructed as a single standpipe, vertical or near vertical, with a pipe diameter that allows granules to flow freely while providing adequate residence time for cooling. The standpipe is cooled by flowing a cooling medium through a passageway that extends along an external surface of the standpipe. The passageway can be provided by a pipe jacket or conduit.
