  • Publication number: 20250339789
    Abstract: Lithium (Li) is a key element for clean energy technologies, and, accordingly, the global lithium demand has been increasing rapidly. Therefore, to meet the Li demand and keep supply chains stable, it is critical to develop efficient lithium extraction technologies that allow exploitation of unconventional lithium resources, such as geothermal brines and inland brine streams. However, the recovery of Li from these resources is challenging due to low Li concentration and high Li/Na, Li/Mg, or Li/Ca ratios. Disclosed herein are novel Zwitterionic Chromatography resins and methods of use for separating Li from salts and other ions.

  • Publication number: 20240391861
    Abstract: The processes disclosed herein for separation of glucaric acid via antisolvent crystallization and azeotropic drying separate monopotassium glucarate and glucaric acid with a recovery yield of greater than 99.9% and 71% at purities of about 95.6% and 98.3%, respectively. Processes disclosed herein recycle antisolvents such as IPA and acetone with greater than 99% recovery with an energy consumption of about 20 MJ/kg for isolation of potassium glucarate and 1,456 MJ/kg for glucaric acid. Using methods and processes disclosed herein, other oxygenated bio-carboxylic acids (e.g., mevalonic acid) can be separated and recovered from fermentation broths and abiotic reaction solutions.

  • Patent number: 11279666
    Abstract: Disclosed herein are methods for the recovery of target bio-base carboxylic acid products using a sorption-based technology with a mixed elution solvent optimized for minimized downstream distillation energy input. The sorption-based technology includes absorbing the targeted bio-base carboxylic acid products onto a non-ionic resin and eluting the targeted bio-base carboxylic acid products with a mixed elution solvent. The mixed elution solvent includes a first solvent and a second solvent. The first solvent has a boiling point that is lower than the targeted bio-base carboxylic acid products and the second solvent is selected from the group consisting of a phosphine oxide or tertiary amine.
