Change in Relaxation State of Polymer Components of Wood During its High-Temperature Biorefining

  • Published:
Fibre Chemistry Aims and scope

The change in relaxation state of polymer components of wood during its high-temperature biorefining and extrusion briquetting and subsequent heating at 380-450°C, i.e., above the thermal decomposition temperature of wood, is analyzed. It is demonstrated that the system can be translated into brittle state by changing the moisture content of the wood and treatment temperature and into forced plastic state by subsequent moistening, heating, and compression-shearing. Carbonization and activation of charcoal briquettes can be combined by subsequent low-temperature pyrolysis in controlled vaporgas environment conditions.
