摘要
从理论上推导出四种情况下的脉冲反应动力学模型,并提出了模型分辨方法。所提模型均得到实验验证,并通过这些模型求得了相应的脉冲反应动力学参数。
The kinetic models of pulse reaction under four cases have been derived theoretically as follows:A→R + SCage Ⅰ: When the product R is of strong adsorption, See Eq.(10). Case Ⅱ: When all components are of weak adsorption, See Eq.(17).A + B→SCase Ⅲ: When the reactant B is of strong adsorption, see Eq.(22). Case Ⅳ: When all components are of weak adsorption, see Eq.(28).Model discrimination methods were also presented. The experimental proofs showed that under the four cases the experimental data obeyed the corresponding models, from which the kinetic parameters of pulse reaction were determined.
