【摘要】 采用双外推法确定了稻壳热解的最概然机理函数为Avrami-Erofeev方程G(α)=[-ln(1-α)]4,热解活化能约为70 kJ.mol-1,小于文献报道的松木等木质纤维素类生物质的热解活化能(一般大于100 kJ.mol-1),这可能与稻壳灰分较高,起到催化热解作用有关。更多还原

【Abstract】 The most probable mechanism function for describing thermolysis of rice husks has been detected to be Avrami-Erofeev equation {G(α)=[-ln(1-α)]4} and the activation energy for thermolysis is about 70 kJ·mol-1,which is less than those for thermolysis of lignocellulose such as pine wood provided by some literature(generally greater than 100 kJ·mol-1).The difference might be resulted from the catalytic effects played by the more abundant ash in the rice husks.更多还原
