中文摘要: |
基于对 8种中国生物质材料非等温热分解的实验结果和动力学分析 ,发现分别源于生物质样品变动和动力学模型变动的表观热解动力学参数 ,即表观活化能E和指前因子A ,满足动力学补偿效应关系。详细讨论了鉴别真、假动力学补偿效应的定量统计判据. |
英文摘要: |
The wood and leaf of eight species are examined by non isothermal means with linear temperature programming in air atmosphere, and a simple kinetic description is developed based on the experimental results and integral analysis method. The relation between the apparent activation energy E and pre exponential factor A is analyzed and it is found that the parameters E and A resulted from the variation of the species and the variation of model functions exhibit kinetic compensation effects. Quantitative and statistical criterion to distinguish between real and false compensation effects is discussed in detail. |
