Hydrothermal Carbonization: 2. Kinetics of Draff Conversion

The hydrothermal carbonization is a promising process to produce carbon-rich products for different application, e. g. as substitute for fossil coal in power plants. The decrease of the oxygen content as main indication of proceeding carbonization is exemplary investigated with draff as feedstock and described by two simple kinetic approaches. By the product composition a distinction between carbonization by carbon dioxide-and water elimination, respectively, was possible.
