  • Method of producing carbon fibers and carbon fiber composites from plant derived lignin and its blends
    Patent number: 11512173
    Abstract: Carbon fiber composites containing lignin carbon fibers are described. The lignin carbon fibers can be derived from organosolv lignin obtained from single source lignocellulosic feedstocks or combinations of such feedstocks or lignin obtained via other pulping or extraction methods. Also described are methods of preparing the carbon fiber composites.
    Type: Grant

  • Spectroscopic Prediction of Formaldehyde Emission and Thickness Swell of Wood Panels
    Publication number: 20090230306
    Abstract: A process for spectroscopic measurement of the emission of formaldehyde from refined wood products destined to be used in the manufacture of composite wood products such as medium density fiberboard (MDF), particleboard, and plywood. The process employs near-infrared (NIR) spectroscopy to measure the absorption of light by the wood furnish; the level of absorption is then related to the formaldehyde emission and thickness swell of the finished wood panel. This process allows for real-time quantitative prediction of future formaldehyde emissions and thickness swell of a composite wood panel.
