The paper discusses the various applications of FTIR absorption spectroscopy as a tool for characterizing waste biofuels for pyrolysis and gasification. The FTIR spectrometer used in the study allows for analysis of solid and liquid waste and biofuel samples. Further, an attached dedicated gas cell is used in the characterization of gases evolving during pyrolysis in a versatile pyrolyser/gasifier attached to the FTIR. The pyrolyser operates in a batch mode and generates large quantities of product samples suitable for further chemical and physical analysis. The paper presents the preliminary results from investigation of the pyro-lysis gases from three different biofuels: pure cotton, wood and fuel made from a mixture of biomass and plastics (ROFIREŽ). First, certain characteristic classes of components are identified in the gas, and second, an attempt is made to explain the origin of the gas compo-nents based on the known chemical constituents of the waste/biofuel.

W artykule omówiono możliwości zastosowania spektroskopii absorpcyjnej FTIR do określania własności odpadów i biopaliw w procesach pirolizy i zgazowania. W badaniach posłużono się spektrometrem FTIR pozwalającym na analizowanie zarówno stałych jak i płynnych próbek odpadów lub biopaliw. Ponadto urządzenie wyposażone jest w moduł z celą pomiarową do analizy próbek gazowych, które otrzymano z uniwersalnego reaktora pozwalającego na przeprowadzenie pirolizy lub zgazowania próbek biopaliw. Reaktor ten wyposażony jest w ruszt stały, a jego podstawową cechą jest możliwość generowania dużych ilości produktów pirolizy/zgazowania do dalszej analizy. W pracy przedstawiono pierwsze wyniki badań spektroskopowych FTIR próbek gazowych uzyskanych z pirolizy trzech biopaliw: bawełny (celulozy), peletów drewnianych i mieszanki biomasy z tworzywami sztucznymi (ROFIREŽ). Uzyskane spektra posłużyły początkowo do identyfikacji charakterystycznych dla danego paliwa grup składników, a następnie do próby powiązania zidentyfikowanych związków gazowych ze składnikami zawartymi w paliwach poddanych pirolizie.
