Fast Pyrolysis for the Thermochemical Conversion of Biomass

At KIT, fast pyrolysis is conducted in a twin-screw mixing reactor. Dry and comminuted biomass is mixed with a preheated heat carrier and heated up within seconds. Upon heating, pyrolytic conversion takes place within seconds, the pyrolysis products are separated from the heat carrier material, and quickly cooled down in a quench.
