  • The effects of supercritical CO₂ on the bending properties and treatment defects of four refractory wood species

    Creator:
    Anderson, Matthew E.
    Abstract:
    It is difficult to treat the heartwood of many wood species with liquid preservatives using conventional liquid processes. Supercritical fluids (SCF) used as carriers of preservatives to impregnate refractory wood species may be an attractive alternative to conventional liquid carriers. While SCF impregnation has many potential advantages, some wood species...

  • Supercritical fluid impregnation with biocides of wood using temperature reduction

    Creator:
    Kang, Sung-Mo
    Abstract:
    Supercritical fluid (SCF) impregnation is a promising preservative treatment method, however, the development of SCF processes has been slowed by a limited understanding of the process. Developing a better understanding of the effects of various process parameters on treatment results would allow for a more rational development of SCF impregnation....
