project of production of synthetic fuels, chemicals and electricity from dry biomass

The Forschungszentrum Karlsruhe (Research Centre Karlsruhe) and the Future Energy GmbH in Freiberg are pursuing a joint project with the goal of producing synthetic fuels from dry residual biomass, such as straw or residual forest wood. In the first process step, the fast pyrolysis of the de-centrally arising residual biomass in regionally operated hybrid reactors takes place at about 500 °C; this results in pyrolysis oil, coke and gas. Oil and coke are mixed to give easily stored and transported pumping and atomisable suspensions (“slurries”), and gas is used in the pyrolysis process. These slurries are transformed in a large entrained-flow gasification system at temperatures of around 1,200 °C and pressures of above 40 bar to a tarless synthetic crude gas. The purified and conditioned synthesis gas is processed to synthetic fuel in an additional processing step after Fischer-Tropsch.
