  • Processes for Making Linear Alpha-Olefins
    Publication number: 20240010579
    Abstract: Fischer-Tropsch processes for converting syngas produces linear alpha olefins at high yield and selectivity in the presence of supported nano-particle catalyst compositions and/or metal carbide/nitride-containing catalyst compositions.
    Type: Application
    Filed: August 10, 2021
    Publication date: January 11, 2024
    Inventors: Jeffrey C. Bunquin, Joshua J. Willis, Partha Nandi, Javier Guzman
  • Supported nanoparticle compositions and precursors, processes for making the same and syngas conversion processes
    Patent number: 11857954
    Abstract: Disclosed are novel supported nanoparticle compositions, precursors, processes for making supported nanoparticle compositions, processes for making catalyst compositions, and processes for converting syngas. The catalyst composition can comprise nanoparticles comprising metal oxide(s), such as manganese cobalt oxide. This disclosure is particularly useful for converting syngas via the Fischer-Tropsch reactions to make olefins and/or alcohols.

  • Compositions Comprising Nanoparticles and Processes for Making Nanoparticles
    Publication number: 20220176366
    Abstract: The present disclosure relates to nanoparticle compositions, catalyst compositions, processes for making nanoparticle compositions and processes for making catalyst compositions. In at least one embodiment, a composition includes a plurality of nanoparticles, where each nanoparticle includes a kernel, the kernels include at least one metal element and oxygen, and the kernels have an average particle size from 4 to 100 nanometers, and a particle size distribution of less than 20%.
