Abstract
A method and device for producing low-tar synthesis gas from biomass. The method according to the invention lowers the tar content in the synthesis gas by splitting the biomass into pyrolysis coke and pyrolysis gas in a fluidized bed reactor, both of which are fed to at least one more fluidized bed reactor, wherein tars in the largely tar-free pyrolysis coke are catalytically split at a higher temperature without the ash melting point being exceeded. The method according to the invention enables the production of largely tar-free synthesis gas.
