Equipment

For research and further development on hydrothermal processes, DBFZ operates several autoclaves and experimental set-ups at different scale. Batch reactors have the advantage in processing a wide range of different biomass, usually without pretreatment steps. Besides the discontinuous reactors, DBFZ also operates continuous lab reactors.

 

electrically heated:

  • Tmax = 300 °C, pmax = 200 bar, heating rate: up to 2.4 K min-1
  • in-situ-sampling of process water possible
  • liquid charging during the process possible

thermal oil heated:

  • Tmax = 270 °C, pmax = 200 bar, heating rate: up to 2 K min-1
  • in-situ-sampling of process water possible
  • liquid charging during the process possible
  • fast, active cooling via thermostat possible

thermal oil heated:

  • Tmax = 300 °C, pmax = 150 bar, heating rate: up to 2 K min-1
  • fast, active cooling via thermostat possible
