Abstract: In present work, Fe-lignin composites were prepared by chemical coprecipitation of metal salts and kraft lignin; the thermal stability of the Fe-lignin mixture was then investigated at temperatures up to 300 °C using thermogravimetric analysis (TGA) and diferential scanning calorimetry (DSC) at a heating rate of 5 °C min−1 under nitrogen atmosphere. The structural characteristics of Fe-lignin thermal treated under diferent temperatures were identifed by Fourier transform infrared (FTIR) spectrometry. The temperature-programmed thermal decomposition (TPD) of Fe-lignin samples was carried out in a fxed-bed reactor; the gaseous products were analyzed qualitatively and quantitatively by an on-line quantitative gas ana ysis system. The temperature and pressure of the reactor were monitored and recorded during the thermal decomposition process. It was observed, the therma decomposition of Fe- lignin samples is a strong exothermic process, and a signifcant amount of heat is re eased from the reaction, which triggers a thermal runaway situation.
