Scientists at the Leibniz Institute for Agricultural Engineering in Potsdam and at the Fraunhofer Institute for Chemical Technology ICT in Pfinztal could demonstrate that the use of near-infrared (NIR) spectroscopy for hydrothermal conversion processes of biomass offer an effective approach for the targeted production of various valuable substances. By means of the NIR substances produced during the process can be quickly identified in a robust and inexpensive manner. Thus, the basis is created to target conversion processes specifically and energy efficiently to the desired substances, while the formation of pollutants is prevented or reduced. Results will soon be published in the scientific journal “Bioresource Technology”.
