采用TGA Q500热分析仪和傅里叶变换红外光谱仪联用技术, 对生物油蒸馏残渣在不同升温速率下的热解动力学特性进行分析研究.结果表明:生物油蒸馏残渣热解可分为小分子物质挥发析出、大分子物质裂解和焦炭产生3个阶段, 热解产物主要为水、烷烯烃、CO2和芳香类物质.在不同升温速率10、20、30℃/min下, 热解主要阶段反应级数均为2级, 活化能分别为74.19、72.52和69.05 kJ/mol.随着升温速率的增大, 热重曲线整体向高温区移动, 热解主要阶段活化能逐渐减小.“,”The pyrolysis behaviors and kinetics of bio-oil distillation residues are investigated by TGA Q500 thermal analyzer and Fourier transform infrared spectrometer at different heating rates. The results show that the process of pyrolysis of bio-oil distillation residues in nitrogen could be separated into three stages, which are the volatilization of small molecule substance, macro molecular substance cracking, and the formation of coke, respectively, with the formation of water, CO2, alkanes, alkenes, as well as small molecules of phenols and aromatic aldehydes. The pyrolysis main stage is two-order reaction at different heating rates, whereas their activation energy are 74.19, 72.52 and 69.05 kJ/mol, respectively. The thermogravimetric curves move to high temperature and the activation energy decreases with the heating rate increasing.
