A simple and accurate model of high-temperature treatment of wood can assist in the process design and the evaluation of performance of equipment. The high-temperature treatment of wood is essentially a drying process under linearly-increased gas temperature up to final temperature of 220-230°C which is a challenging process to model. This study is aimed to assess the applicability and accuracy of the reaction engineering approach (REA) to model the heat treatment of wood. In order to describe the process using the REA, the maximum activation energy (ΔE(v,b)) is evaluated according to the corresponding external conditions during the heat treatment. Results indicate that the REA coupled with the heat balance describes both moisture content and temperature profiles during the heat treatment very well. A good agreement towards the experimental data is indicated. It has also been shown that the current model is highly comparable in accuracy with the complex models.
一种简单而精确的高温木材处理模型可以辅助工艺设计和设备性能评估。木材的高温处理本质上是在气体温度呈线性增加的情况下进行的干燥过程，最终温度达到 220-230°C，这是一个具有挑战性的建模过程。本研究旨在评估反应工程方法（REA）在木材热处理建模中的适用性和准确性。为了使用 REA 来描述该过程，根据热处理过程中的相应外部条件来评估最大活化能（ΔE(v,b)）。结果表明，REA 与热平衡相结合可以很好地描述热处理过程中的水分含量和温度分布。实验数据表明吻合度很好。此外，还表明当前模型在准确性方面与复杂模型高度可比。
