Combustion characteristics of bio-oil from sewage sludge were investigated using thermogravimetry (TG) and Fourier Transform Infrared Spectroscopy (FT-IR) techniques. The combustion process could be divided into two weight loss stages. Light compounds volatilized and were oxidized in the first stage and the heterogeneous combustion between oxygen and heavy compounds happened in the second stage, which were confirmed by FT-IR technique. Most weight loss occurred in the first stage. The effect of heating rate was also studied and higher heating rates were found to facilitate the combustion process. The kinetic parameters of the two stages were calculated and the change of activation energy indicated higher heating rates benefited combustion.
