采用热重-傅里叶变换红外光谱（TG-FTIR）研究了蛋白核小球藻溶剂解液化生物原油燃烧过程中气体产物的动力学行为和演化特征。结果表明，不同乙醇/水混合比例所得的生物原油存在明显差异。乙醇-水共溶剂的生物原油的着火温度低于纯水溶剂的生物原油，提高了综合燃烧指数。其中，BO40（乙醇含量为40%的生物原油）具有最低的着火温度（163.4℃）和较高的综合燃烧指数（1.24×10−06min−2℃−3）。 C单键H、C双键O、C双键C、CO2、CO和HCN是主要的气态产物。与其他生物原油样品相比，BO40的C单键H、C双键O和C双键C第一峰强度较高，CO峰强度较低，表现出更好的燃烧特性。
The kinetic behavior and evolution characteristics of gaseous products during the combustion of biocrude oil from solvolysis liquefaction ofChlorella pyrenoidosawere 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). Csingle bondH, Cdouble bondO, Cdouble bondC, CO2, CO and HCN were the main gaseous products. Compared to other biocrude oil samples, BO40 had high first peak intensity of Csingle bondH, Cdouble bondO and Cdouble bondC, and low peak intensity of CO, which performed better combustion characteristic.
