| 摘 要： | 根据苯与长链烯烃烷基化反应动力学方程,笔者利用在负载杂多酸中孔分子筛催化剂上液-固相反应的实验数据进行参数估值,确定了反应速率常数、扩散系数、反应活化能和扩散活化能参数,建立了考虑内扩散影响的苯与长链烯烃烷基化反应动力学模型.结果表明,所建动力学模型具有较高的计算精度,符合苯与长链烯烃烷基化反应规律. |

| Abstract: | A reaction kinetic equation for alkylation of benzene with long chain olefin over a solid acid catalyst, comprising a heteropoly acid supported on a mesoporous molecular sieve, was first developed The kinetic parameters, such as reaction rate constants, diffusion coefficients, reaction activation energy and the diffusion activation energy, were determined through parametric estimation by using the experimental data of alkylation in a liquid slid reaction system The kinetics model of alkylation, in which internal diffusion factors were considered, was established The results indicated that the established kinetics model exhibited a highly simulation precision and was in accord with the laws of the alkylation |
| Keywords: | solid acid benzene olefins alkylation kinetics |
