  • 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: 20140099346
    Abstract: An iron oxide containing effect pigment, and methods for producing and using the same are discussed. The iron oxide containing effect pigment may include an iron oxide coating in direct contact with a particulate substrate, which may have high levels of hematite, magnetite, or maghemite; and low amounts of toxic metals. A method for producing the pigment may include chemical vapor deposition of iron pentacarbonyl onto a particulate substrate. The iron oxide containing effect pigments may be incorporated into compositions, such as cosmetics.

  • Publication number: 20130344239
    Abstract: A process for production of a granular urea product in a fluidized-bed where: small droplets (10) of fresh urea melt are contacted with a cooling medium to form solid particles, said solid particles (11) are contacted with droplets of urea melt (12) which are larger than said germ particles, the solid particles and said droplets forming together larger solid particles (13), and said solid particles further increasing their size step by step and upon contact with droplets of urea melt, until the solid particles reaches a given size, and said solid particles are then subject to a further growing process by contact with liquid droplets now smaller than the solid particles, until a desired size of the granular product is reached.

    Abstract: Mechanically fluidized systems and processes allow for efficient, cost-effective production of silicon. Particulate may be provided to a heated tray or pan, which is oscillated or vibrated to provide a reaction surface. The particulate migrates downward in the tray or pan and the reactant product migrates upward in the tray or pan as the reactant product reaches a desired state. Exhausted gases may be recycled.
