| 摘 要： | 以参数敏感性定义作为理论基础和数学依据,证明了热点轨迹拐点是反应系统的参数敏感点,从理论上给出了固定床反应器采用一维拟均相模型,进行一级反应,冷却介质温度不变,且与物料入口温度相等时,反应系统安全操作所允许的温度上限,并利用临界操作曲线热点和超临界操作曲线拐点之间的关系,推导出反应系统安全操作的临界判据,该关联式与El-Swai等人的实验结果吻合很好.

| Abstract: | The parametrically sensitive point of a reactor was proved to be an inflection point of the hot spot locus by taking the definition of parametric sensitivity as the theoretical basis and mathematical starting point. The upper limit of the safe operation temperature was derived with respect to a one dimensional paeudo - homogeneous plug flow reactor with constant wall temperature, in which a first order reaction was carried out. With regard to the relation between the hot spot on the critical operation curve and the inflection point on the supercritical one, a criterion of the safe operation of reaction systems is obtained. This formula agreed well with the experimental data of El - Swai et al. |
