【摘要】 根据作者提出的结构-反应活性关系预测出链烷烃裂解时主要基元反应的动力学参数。以乙烷十丙烷混合裂解为例,就不同的反应网络进行了对比分析,提出了反应个数尽可能少而又能全面、真实反映裂解过程的反应网络。用Gear法模拟求解了由此建立的C₄单烃及其混合烃裂解的结构动力学模型,模型预测的产物分布与文献发表的中试数据吻合很好。更多还原

【Abstract】 The kinetic parameters of main elementary reactions for pyrolysis of paraffins are predicted according lo the dependence of structure -reactivity proposed by the authors. The pyrolysis for a mixture of ethane-propane based on different reaction networks are simulated and compared with pilot data. Thus a reaction network which can describe the process properly and really and has a smaller reaction number is proposed in this paper. Gear method is used to solve the structural kinetic model of C4 paraffin pyrolysis. The predicted product distributions based on the model agree well with pilot data published in the literature.更多还原
