Biocoal in Minutes - Biomass Steam Processing on the Pilot Plant Scale

J. Steinbrück, D. Reichert, B. Genova, M. Rossbach, L. Walz & H. Bockhorn
The use of steam to carbonize biomass has been tested in a laboratory screw reactor at atmospheric pressure and at temperatures between 250 and 400°C for short reaction times between 30 and 150 minutes. This treatment has been named biomass steam processing (BSP). The resulting biocoal is compared with products of hydrothermal carbonization (HTC) of biomass in liquid, pressurized water at typical HTC reaction parameters i.e. 180 to 240°C, 15 to 33 bar, 0.5 to...
