AB  - Hydrothermal carbonization (HTC) of biomass takes place in a closed reactor at temperatures between 180 - 260° C and self-sustained pressure using the influence of subcritical water as a reaction medium. In most cases, treatment duration is within the range of 1-24 h. The outcomes of the process are, a solid material with a higher carbon content, called hydrochar and the residual HTC wastewater. Due to their surface structure and tunable properties, hydrochars have been applied as been applied as solid fuels, soil conditioners and adsorbents1).
Miscanthus giganteus, a perennial purpose-grown crop, has been primarily used as an energy source. However, with low bulk density and moisture and significant transportation costs, thermochemical pretreatment of this feedstock has been suggested as the best way to overcome these issues and to increase its use-value. Besides, miscanthus is characterized by a very low ash content and this attribute is advantageous for HTC2).
The scope of this work was to offer new insights into the application of miscanthus hydrochars as adsorbent materials. The main objectives were the following: a) valorization of Miscanthus giganteus for the production of an added-value material (adsorbent) at different HTC temperatures and a short residence time b) application of the 'as produced' hydrochars in the adsorption of Cu2+ and NH4+ c) investigation of the influence of the production temperature and correlation of the process severity to the properties and adsorption behaviour of the samples.

AB  - In the framework of bio-circular economy, miscanthus biomass was valorized through a single-stage, low severity hydrothermal carbonization process. The produced hydrochars were characterized using elemental and spectroscopic methodologies. It was determined that as the temperature increased so did the C content (47.9 and 68.9% for the samples prepared at 180 and 260 degrees C, respectively), whereas the O content decreased (from 44.2 to 25.5%, respectively). The adsorption behaviour of the hydrochars was investigated in the adsorption of Cu2+ and NH4+ and MIS-180 was determined as the optimum sample, achieving qmax values of 310 and 71 mg g-1, respectively. Isotherm and kinetic analysis indicated the higher number of O-containing functional groups of MIS-180 as the main reason for its higher adsorption capacities. Furthermore, Cu2+ adsorption followed the 2ndorder kinetic model, whereas NH4+ adsorption followed the 1st-order kinetic model, due to the different mechanisms involved, inner-sphere and outer-sphere complex formation, respectively.
