A Raman spectroscopic study of the pyrolysis of lactose and tannins — •Simon Brehm, Cameliu Himcinschi, Jakob Kraus, and Jens Kortus — TU Bergakademie Freiberg, Germany

Lactose and tannin are naturally occurring and eco-friendly alternatives to commonly used binders for carbon-bonded alumina filters that are applied in steel melt filtration. A contribution to understand the production process of these filters is the investigation of the pyrolysis process of the binders. In this work, lactose and different tannins were investigated by in situ and ex situ Raman spectroscopy. The transformation of the tannin and lactose molecules to a system of amorphous carbon and at even higher temperatures to nanocrystalline graphite could be observed in the Raman spectra. In addition, intermediate pyrolysis products of the investigated tannins as well as their pyrolysis temperatures could be determined.
