应用理想喷淋床反应器模型,从实验结果计算了使用Pd-Al_2O_3纤维催化剂时,在低温下裂解汽油中双烯加氢的速度常数及活化能。结果表明,双烯加氢反应基本上可按一级反应处理。按照串行一级反应模型,从实验结果计算了不同温度下的选择因子,从而进一步计算了单烯加氢的速度常数和活化能。此外,还按上述模型计算了单烯选择性。计算值与实验值大体上一致。同时对单烯选择性较好的原因也作了解释。
Based on the experimental results, the rate constant and activation energy of diolefins hydrogenation in pyrolysis gasoline at low temperature were calculated using Pd-Al 2 O 3 fiber catalyst. The results show that the diolefins hydrogenation reaction can basically be a first-class reaction. According to the serial first-order reaction model, the selection factors at different temperatures were calculated from the experimental results to further calculate the rate constant and activation energy of the hydrogenation of mono-olefins. In addition, the mono-olefin selectivity was also calculated according to the above model. The calculated value is in agreement with the experimental value. At the same time, the reasons for the better selectivity of mono-olefins are also explained.
