Abstract:利用热重(TG)-傅里叶变换红外光谱(FTIR)联用对生物柴油的热解及气体产物的释放特性进行了研究,并通过非预置模型法的Vyazovkin算法和Avrami理论计算了生物柴油热解的活化能和反应级数等动力学参数。生物柴油在554~773K区间存在失重率约为87.59%的失重阶段,伴随的热解气体产物主要包括CO2、H2O、CH4和其他有机化合物,其中主要气相产物析出规律一致,但浓度存在差异。随着升温速率的提高,生物柴油的热解向高温区移动。同时,生物柴油的热解呈现多段特性,在不同转化率区间,动力学参数变化较大,活化能为100.48~151.14kJ/mol,反应级数为1.21~1.24。
