The kinetic behavior and evolution characteristics of gaseous products during the combustion of biocrude oil from solvolysis liquefaction of Chlorella pyrenoidosa were investigated by thermogravimetry-Fourier transform infrared spectroscopy (TG-FTIR). The results indicated the biocrude oil obtained from different ethanol/water mixed ratio had obvious difference with each other. The ignition temperature of biocrude oil from ethanol-water co-solvent was lower than that from pure water solvent, which promoted the comprehensive combustion index. Especially, BO40 (biocrude oil obtained from 40% ethanol content) achieved the lowest ignition temperature (163.4°C) and high comprehensive combustion index (1.24×10-06min-2°C-3). CH, CO, CC, CO2, CO and HCN were the main gaseous products. Compared to other biocrude oil samples, BO40 had high first peak intensity of CH, CO and CC, and low peak intensity of CO, which performed better combustion characteristic.
