  • Publication number: 20240270577
    Abstract: Methods of producing cathode material precursors from metal carbonyl complexes are described.
    Type: Application
    Filed: May 31, 2022
    Publication date: August 15, 2024
    Inventors: Alex Carpenter, Turner Boris Caldwell
  • Publication number: 20240055681
    Abstract: A method for recovering the valuable materials from energy storage devices (e.g., spent rechargeable lithium batteries, especially those batteries using nickel-based or nickel and cobalt containing cathode materials) are described. In particular, the proposed method applies carbonyl technology, also known as vapometallurgy, to regenerate pure materials which can be reused as raw materials for making active cathode materials for new lithium batteries.

  • Publication number: 20230202954
    Abstract: Catalyst preforming rates during hydroformylation may decrease in the presence of carbonates. Carbonate mitigation methods may comprise treating a hydroformylation reaction product with an aqueous carboxylic acid under oxidizing conditions to form a deactivated catalyst aqueous solution having a pH of about 4 or less, reducing the hydroformylation reaction product to form a reduced reaction product, conveying a gas stream through the reduced reaction product to strip carbon dioxide therefrom, contacting caustic aqueous solution with the stripped reduced reaction product to form partially spent caustic aqueous solution, combining at least a portion of the partially spent caustic aqueous solution with the deactivated catalyst aqueous solution to form a combined aqueous mixture sufficiently acidic to decompose carbonate, and extracting a Group 9 transition metal carboxylate from the combined aqueous mixture into an organic phase.

  • Patent number: 11512035
    Abstract: The present disclosure provides a method for forming oxygenates from olefins which includes hydroformylation of aldehydes as a formyl source alternative to syngas. In at least one embodiment, a hydroformylation process is performed at low-temperature and at or near ambient pressure for the conversion of olefins into aldehydes, thus reducing the formation of by-products such as via double bond or skeletal isomerization of the feedstock; or via further conversion of the formed aldehydes and alcohols. In at least one embodiment, the use of gaseous olefinic products (e.g., ethylene) instead of strained olefins (e.g., norbornene) improves the control equilibria in transfer hydroformylation reactions.
    Type: Grant
