固定床反应器进行n级反应的飞温判据

本文以一级反应系统参数敏感性理论为依据，给出ｎ级反应系统以ε为扰动参数的临界热点温度表达式，内插得到该系统的飞温判据。结果表明：反应级数越大，系统抵抗外部环境干扰的能力越强，安全操作区域越大，参数敏感区域越小。

The Criterion for Runaway of the n-th Order Reaction in Fixed Bed Reactor

Based on the theory of parametric sensitivity of the first order reaction systems,the formula of the temperature of the critical hot spot with e as a perturbation parameter ,and the runaway criterion for the n-th order reaction systems are derived respectively. The results indicate that the higher the reaction order is, the stronger the resistible capacity will be to the perturbation of operation parameters and external surroundings. Also, the larger safe operation region and the smaller parameter sensitivity region will be expected at higher reaction order.
