固定床催化反应器逆响应的动态特性

Dynamic characteristics of fixed bed reactors——Wrong way behavior

总结了固定床催化反应器中逆响应行为研究的现状。通过对有关文献的分析，发现固定床催化反应器中这一固有特性存在的可能性及其对固定床催化反应器正常运行操作的潜在危害。依据文献中对固定床催化反应器这一固有特性的实验和理论研究（模拟和预测），总结了各种因素对逆响应行为的影响并分析了各个模型的应用范围及其不足，提出了今后的研究方向。

The current status of study is reviewed on the wrong way behavior in fixed bed catalytic reactors.The wrong way behavior is proved to be the intrinsic specific characteristics of fixed bed catalytic reactors and has potential harms on the normal operation of the reation systems. Moreover, based on the experimental and theoretical studies (modeling and predicting)of the relevant literatures on the dynamic characteristics, effects of various factors on the wrong way behavior are reviewed and the applicable scope of each model and its deficiency are also discussed.Finany, the diraction is pointed out for research work in the future.
