In recent years, magnetic hydrochars have experienced an increasing research interest. Their promising prospects comprise the use in filtration, adsorption, and even biogas production. Knowledge is limited to the use of different magnetic char-like materials in these fields. Nevertheless, knowledge lacks certain information on the influence of the production parameters on the characteristics of the final material. However, this information is necessary to tune the properties of magnetic hydrochar with respect to the needs of the aforementioned various applications. Therefore, this on-going project, co-financed by the German Federal Ministry of Education and Research (BMBF, Grant-No.: 03VNE1031C), focuses on the use of a metallic residue and beech wood for the production of magnetic hydrochar in a single-step synthesis. First results from an experimental design (face-centered central composite design) with varying temperature, holding time, and mass ratio of metal and wood will be presented. The outcomes will be discussed in view of preferred characteristics and the suitability of the resulting magnetic hydrochar for the use in filtration of flue gases and effluent streams.
