本文采用正态函数逼近分析的方法,讨论了活性分布宽度对球形催化剂有效因子的影响。对于具有幂指数型动力学的放热反应,活性组分集中在最佳位置处的无限薄层上可得到最大有效因子η_(max),然而,分布宽度的略微增加会使有效因子迅速降至最小有效因子η_(max)。随着β值的增加,这种现象更加显著。若活性组分以一定宽度存在于颗粒内部,那么,分布位置必须向的内侧偏移一定距离才会使催化剂有最佳有效因子。因此,为使真实催化剂具有最佳有效因子,就必须在附近对分布宽度和位置再次进行优化。
In this paper, the normal function approximation method is used to discuss the effect of active distribution width on the effective factor of spherical catalyst. For exothermic reactions with exponential kinetics, the maximum effective factor, η max, can be obtained by focusing the active component on the infinite layer at the optimum position. However, a slight increase in the distribution width causes the effective factor to drop rapidly To the minimum effective factor η_ (max). With the increase of β, this phenomenon is more significant. If the active component is present within the particle at a certain width, the distribution must be offset to the inside of the bladder to provide the best possible catalyst effectiveness. Therefore, in order for the true catalyst to have the best possible efficiency factor, the width and location of the distribution must be optimized again near .
