  • Use of Multifunctional CO2 for Depolymerization of Polyethylene Terephthalate
    Publication number: 20240117140
    Abstract: A high-efficiency, low-energy consumption and environmental-friendly recycling technology for PETE plastic waste is disclosed. The degradation of PETE plastic waste includes a method for attacking the —O— ester linkage in the repeat unit of PETE plastic with water in saturated pressure and CO2 in supercritical (Sc) conditions.
    Type: Application
    Filed: December 11, 2023
    Publication date: April 11, 2024
    Applicants: University of Wyoming, Washington State University
    Inventors: Maohong Fan, Wenyang Lu, Jinwen Zhang

  • SYNTHESIS OF HIGH PURITY BETA-SILICON CARBIDE
    Publication number: 20210276876
    Abstract: A clean and low-cost approach for reusing waste residual from coal utilization and sandstone powder is disclosed. The coal waste residual may be produced from any thermal, solvent extraction or combination process. For example, a sustainable and environmentally friendly method for synthesis of beta-silicon carbide (?-SiC) using, for example, the residual of Powder River Basin (PRB) coal extraction derived from ethanol and supercritical CO2 (EtOH-SCC) extraction combined with natural sandstone.
