Wet Torrefaction of Norwegian Biomass Fuels

Q.V. Bach, K.-Q. Tran & Ø. Skreiberg
Wet torrefaction of biomass for bioenergy applications involves the use of hot compressed water as reaction environment to improve the fuel properties of the biomass materials, which among others includes increased heating values and better grindability. The process may be defined as hydrothermal pyrolysis of biomass fuels within the temperature window of 200–260 °C. Compared with dry torrefaction, wet torrefaction is capable of upgrading biomass fuels with very high moisture contents without the need of...
