The Use of FT-IR for the Determination of Liquid Products Properties after the Tyres Thermal Degradation

摘要

The article deals with the identification of a chemical structure of pyrolysis liquid occurring by the thermal degradation of tyre debris within the temperature interval from 500°C to 650°C and the temperature increase steps of 50°C in individual experiments and with the use of analytical methods GC/MS, FT-IR and the elementary analysis. The measured FT-IR spectra indicate the representation of functional groups included in measured samples. They could be used for the determination of basic chemical properties. There were changes in the chemical composition monitored as well as the creation of functional groups in the pyrolysis liquid on the basis of FT-IR spectra and GS/MS outcomes.
