Biomass Conversion by Fast Pyrolysis

N. Tröger, E. Dinjus, D. Richter & R. Stahl
For the fast pyrolysis a process development unit (PDU) for a continuous biomass throughput of 10­20 kg/h has been planned, built and is currently being operated at the Karlsruhe Institute of Technology. A broad feedstock variety of several biomass residues has been studied. Straw chops or other small, dry biomass particles are mixed with an excess of a hot heat carrier in a twin screw mixer reactor with two rotating screws (LR-mixer reactor). The biomass...
