Abstract: 
The production of carbonaceous materials from biomass has recently attracted much attention. The hydrothermal carbonization process (HTC) is of great importance because it can generate chars (HTC-chars) that are rich in organic carbon from biomass with high water content; these chars have the potential to be used in a wide range of applications. In this review we discuss an investigation into the production of carbonaceous materials from four types of wetland biomass (reed, typha, juncus and carex) using hydrothermal carbonization. Furthermore, the influence of reaction temperatures on the carbonization process was examined by varying the temperature over a range of 180 to 230 degrees C. A comparison between the properties of the resulting chars was performed, focusing on elemental analysis and nitrogen adsorption. Depending on the biomass, the HTC-chars were found to contain around 53 to 60% of the carbon originally present in the biomass. There was a clear positive correlation between reaction temperature increase and the carbon proportion of the HTC-char of all variants. The atomic ratios H/C and O/C of the chars were found to be more similar to lignite than those of the raw material. The study shows that wetland biomass has great potential for the production of HTC-char.
