Beschreibung
Zusammenfassung:	Disclosed is a method for converting carbonaceous raw materials and in particular biomass into fuels, comprising the steps: - gasifying the carbonaceous raw materials in a gasifier, wherein heated steam is introduced into the gasifier and is used for the gasification; - cleaning the synthesis gas produced during the gasification; - changing the temperature of the synthesis gas; - converting the synthesis gas into a liquid fuel by means of a catalysed chemical reaction, wherein a Fischer-Tropsch reactor is used for this conversion, wherein the gasification is an allothermal gasification and the heated steam is used both as the gasification agent and as the heat carrier for the gasification and has a temperature above 1000°C and a further gaseous medium is fed to the gasifier together with the steam. Further disclosed is a device for converting carbonaceous raw materials such as biomass into liquid fuels, comprising a gasifier, in which the carbonaceous raw materials are gasified by means of heated steam, at least one cleaning unit for cleaning the synthesis gas produced during the gasification, at least one temperature-changing unit for changing the temperature of the resulting synthesis gas, and a Fischer-Tropsch reactor for converting the synthesis gas into a liquid fuel, wherein the device has at least one heating device which heats the steam to a temperature above 1000°C.
