Data for: Vitrification of environmentally harmful by-products from biomass torrefaction process
Spectroscopy in the mid-infrared range: 4000 - 400 cm-1 was carried out using a Brucker 70V Fourier spectrometer. The samples were prepared in the form of KBr pellets. Measurements were made by the transmission technique, and the spectra were recorded on the scale of absorbance at 256 scans and 4 cm-1 resolution. XRD tests were conducted using the powder method on an X'Pert Pro diffractometer from Philips. A measurement step of 0.008°and count time of 50 s were used. Phase identification was performed based on data from the ICDD PDF-4 database. High-temperature microscopy was carried out using a Misura 3.232 hot stage microscope.
