摘要: 以稍加修正的对数概率密度函数逼近固定床对脉冲函数输入的应答,导出了形如正态概率分布函数式,计算简捷的固定床透过曲线的近似表达式,并且证明,该式能相当准确地逼近固定床各类模型的精确透过曲线,也能准确地预测床内浓度场或温度场随时间的变化.

Abstract: A simple, easy-to-use approximate equation, in the form of a normal probability distribution function, was derived for breakthrough curves of fixed-bed reactors or adsorbers. The equation predicts breakthrough curves and evolution of concentration or temperature distribution in fixed beds, with an accuracy higher than, or comparable to, other equations previously proposed.
