Abstract

The present invention relates to a continuous method for the hydrothermal carbonization of renewable raw materials and organic residues, in which, in a first processing stage, a pressure increase essentially to the pressure level of the carbonization occurs, in the second processing stage, the carbonization, which is performed at a pressure of at least 5 bar and at most boiling temperature, the obtained carbonized product is at least partially settled as sediment, and the filling height of the water in the second processing stage is set by removing water, and the temperature of the sediment delivered from the second processing stage is reduced by the vaporization of water and it is supplied to the third processing stage, drying which is heated using steam, in which the drying is performed in steam atmosphere, and subsequently discharged from the process.
