摘要: 本文就不同体系(单纯扩散体系和一次等温吸附体系)同时采用脉冲响应和阶跃响应两种测定方法,通过响应曲线拟合,对算出的速度因子的灵敏度进行比较.解析结果可见,在应用非稳定信号输入响应法测算固定床中速度因子时,脉冲响应法要比阶跃响应法精确.

Abstract: Shot and Step response measurements were carried out with inert bed and adsorption bed both under isothermal conditions. Parameter values were determined from a time domain analysis of the measured input and response signals. Sensitivity test in the parameter values showed that shot response measurements may give more reliable parameter values than step measurements.
