摘要

由于大庆重石脑油正构和异构烷烃、五元和六元环烷烃的裂解性能差异较大，在大庆重石脑油8集总动力学模型的基础上，建立了将重石脑油划分为4个原料集总的10集总动力学模型。引入浅度裂解的概念，采用分层和分步相结合的方法求取了反应速率常数，并进一步回归得到了各反应的活化能和指前因子。实验值与预测值对比分析表明，该模型具有更好的预测能力，可为更宽范围的原料预测提供参考数据。

Abstract

Due to the large difference of pyrolysis performance of n-paraffin

i-paraffin

5-cyclanes and 6-cyclanes in Daqing heavy naphtha

it may be necessary to modify the 8 lumped component kinetic model. A 10 lumped component kinetic model with 4 stock lumped component is proposed for the pyrolysis of Daqing heavy naphtha.The kinetic parameters in the new model can be determined as follows: using the conception of shallow pyrolysis

the reaction rate constants are estimated by combining lay-method and stepwise-method

including their activation energy and pre-exponential factors.The better agreement between experimental and calculated data shows that this model is of predicting ability with better accuracy in wider range of feedstocks.
