| 摘 要： | 采用气液固三相滴流床反应器，在反应温度(493~558) K，氢压(1.5~3.0) MPa和氢油体积比为200~800条件下，研究了苯并噻吩和二苯并噻吩模型化合物在钴钼基催化剂上加氢脱硫反应及其宏观动力学。根据幂函数型动力学方程，以全局通用算法结合马夸特算法对动力学参数进行估值，建立了与实验数据相吻合的柴油中含硫模型化合物的深度加氢脱硫反应动力学模型。其中,苯并噻吩的一级方程活化能为3.985×104 J·mol-1，二苯并噻吩的二级方程的活化能为3.130×104 J·mol-1。残差检验和统计学考察表明，模型计算结果和实验数据吻合良好。

| Abstract: | In the three-phase trickle bed reactor under the conditions of (493-558) K, (1.5-3.0) MPa and H2/Oil volume ratio (200-800), the hydrodesulfurization reaction and its macrokinetics were studied over CoMo/Al2O3-TiO2 catalyst with the model compounds of benzothiophene and dibenzothiophene. According to the power-law type model, the parameters were estimated with the Universal Global Optimi-zation and Marquardt method. The results showed that the activation energy of benzothiophene on the first models agreeed well with the experimental data. |
