柚皮粉热解特性及动力学分析

Pyrolysis characteristics and kinetic analysis of pulverized shaddock peel

采用热重分析仪对柚皮粉在氮气气氛下的热解特性进行试验研究,考察了不同升温速率(10、20、30、40和50℃/min)下柚皮粉的热重(TG)曲线和微商热重(DTG)曲线。采用不同方法对实验数据进行回归拟合,探讨了柚皮粉热解机理,并求出反应动力学活化能和频率因子。

Pyrolysis characteristics of pulverized shaddock peel were investigated under nitrogen atmosphere. The thermogravimetric （TG） curve and differential thermogravimetric （DTG） curve of pulverized shaddock peel with different heating rates （10,20,30,40 and 50℃/min） were examined. The experimental data were fitted by different methods,and the pulverized shaddock peel pyrolysis mechanism was discussed. Then activation energy and frequency factor of reaction kinetics were obtained.
