| 20100101142 | METHOD FOR THE WET-CHEMICAL TRANSFORMATION OF BIOMASS BY HYDROTHERMAL CARBONIZATION - A method for converting biomass into higher-energy-density solids, in particular carbon, humus or peat, is described. In the method, organic substances from the biomass are suspended in water to form a suspension and at least a part of the suspension to be converted is heated to a reaction temperature and is converted into higher-energy-density solids by hydrothermal carbonization at elevated pressure. The conversion is carried out in a reaction volume which is located underneath the Earth's surface. Uniformity of the product quality and an increase in the economic efficiency of the process are achieved by the method. | 04-29-2010 |
