摘要：根据长链烷烃催化脱氢反应机理,采用某新型国产长链烷烃脱氢催化剂,建立了工业反应条件下的直链烷烃脱氢制单烯烃表观反应动力学模型和催化剂失活模型。以在轴向连续流动固定床微型反应器中C10~C13直链烷烃脱氢反应的实验数据为基础,采用多元函数包维尔（Powell）法优化计算了反应速率常数、失活速率常数、失活级数与活化能,实验值与计算值拟合效果良好。动力学模型参数分析表明了所建模型动力学与热力学的合理性。
Based on the reaction mechanism of heavy paraffin catalytic dehydrogenation, with a new domestic catalyst of paraffin dehydrogenation as research objective, apparent reaction kinetic model and catalyst deactivation model of heavy paraffins dehydrogenation to mono-olefins were established under industrial reaction conditions. Based on the experimental data of C10--C13 paraffins dehydrogenation in an axial continuous flow fixed bed microreactor, the reaction rate constants, deactivation rate constants, deactivation order and activation energy were calculated by multivariate function Powell method, and the fitting effect of experimental values and calculated values is good. The analysis of kinetic model parameters showed the rationality of kinetics and thermodynamics.
