摘要：
The invention relates to a method for utilizing biomass, in which the biomass is pyrolysed within a temperature range from 550°C to 750°C to obtain driven-out gas and remaining carbon-rich solids. It is an object of the invention to specify a method for utilizing biomass, which is based on comparatively expensive feedstocks, but in return gives products of value with unusually good properties, the proceeds of which make the process economically viable. This object is achieved firstly by the use of biomass which has a lignin content of 10 to 30% by weight and a water content of 5 to 25% by weight, and by virtue of the residence time of the biomass within the temperature range from 550 to 750°C being ten to sixty minutes.
