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 differential scanning calorimetry (DSC) at a heating rate of 5 °C min−1 under nitrogen atmosphere. The structural characteristics of Fe-lignin thermal treated under different temperatures were identified by Fourier transform infrared (FTIR) spectrometry. The temperature-programmed thermal decomposition (TPD) of Fe-lignin samples was carried out in a fixed-bed reactor; the gaseous products were analyzed qualitatively and quantitatively by an on-line quantitative gas analysis system. The temperature and pressure of the reactor were monitored and recorded during the thermal decomposition process. It was observed, the thermal decomposition of Fe-lignin samples is a strong exothermic process, and a significant amount of heat is released from the reaction, which triggers a thermal runaway situation.
