Abstract
A method for producing an odor-free HTC coal, at least comprising the following steps: a) providing a biomass; b) performing a hydrothermal carbonization in order to produce a carbon sludge, the carbon sludge comprising HTC coal and HTC process water; c) separating HTC coal and HTC process water by a mechanical dewatering process; d) heating the HTC coal to a temperature of at least 150 degrees Celsius in order to remove highly volatile carbon compounds.

A process for producing an HTC carbon, at least comprising the following steps:
- a) providing a biomass;
- b) performing a hydrothermal carbonization to produce a carbon sludge;
- where said carbon sludge comprises HTC carbon and HTC process water;
- c) separating HTC carbon and HTC process water by a mechanical dewatering operation;
- d) heating the HTC carbon for removal of volatile carbon compounds to a temperature of at least 150 degrees Celsius.
An HTC carbon, wherein the HTC carbon at an ambient pressure and 20 degrees Celsius is odorless with respect to volatile carbon compounds.
