  • Core-shell composite particles and methods of making same
    Patent number: 11970429
    Abstract: A composite particle is described herein. The composite particle can contain a seed particle of an agricultural treatment material and a shell disposed on the seed particle, wherein the shell comprises a clay.
    Type: Grant
    Filed: October 1, 2020
    Date of Patent: April 30, 2024
    Assignee: CARBO CERAMICS INC.
    Inventors: Keith Hogan, Steve Canova, David Osby
  • Mineral additive blend compositions and methods of use thereof
    Patent number: 10982163
    Abstract: Mineral additive blend compositions and a method for operating a furnace are provided in order to avoid combustion problems such as agglomeration, deposition, corrosion and reducing emissions. A method for operating a furnace, such as a fluidized-bed reactor, pulverized-fuel combustor, and grate combustor, includes introducing fuel and a mineral additive blend including a clay and a functional mineral into the furnace.

  • Mineral Additive Blend Compositions and Methods for Operating Combustors for Avoiding Problems such as Agglomeration, Deposition, Corrosion and Reducing Emissions
    Publication number: 20150122161
    Abstract: The method further includes heating at least a portion of the inorganic compound-containing material and clay, such that at least a portion of the clay is at least partially calcined, and the at least partially calcined clay and functional mineral adsorb at least a portion of the inorganic volatile compounds present in the furnace and react with the ash produced during fuel combustion increasing its refractoriness. The method further includes removing at least a portion of the at least partially calcined clay and adsorbed inorganic compounds from the furnace.
