  • Method and device for thermal ablative pyrolysis of biomass
    Patent number: 7438785
    Abstract: A method for the pyrolosis of biomass with the aid of a heating element and a feed for guiding the biomass. During pyrolysis, the heating element and the biomass are pressed against each other at a pressure of 5 bars-80 bars. A device for pyrolysing biomasses, comprises a material supply and a pyrolysing station. The material supply comprises elements for generating a pressure of between 5 bars and 200 bars, pressing the raw material which is to be pyrolysed against the pyrolysing station. The pyrolysing station comprises a heating element which is heated to a temperature of between 300° C. and 1000° C. in an operational state.
