提出了一种“性能指数”，它是支护性能的超几何平均值。根据催化反应转化率与表观速率系数(k)的关系，通过建立“性能指数”与表观速率系数的相关性，建立了载体性能与二苯并噻吩（DBT）加氢脱硫（HDS）反应转化率的定量关系模型。并给出了性能变量对催化活性贡献率的分析方法。通过拟合不同载体性能催化剂上DBT - HDS转化的一系列实验数据，估计了模型参数。结果表明，该模型的总平均相对偏差为1.43%，预测偏差为2.21%。
A “property index” has been developed, which is a supergeometric average of the support properties. Based on the relationship between the catalytic reaction conversion and the apparent rate coefficient (k), a quantitative relationship model was established between the support properties and the conversion of dibenzothiophene (DBT) hydrodesulfurization (HDS) reaction by building a correlation between “property index” and the apparent rate coefficient. Moreover, an analysis method about the contribution rate of the property variables to catalytic activity was provided. The model parameters were estimated by fitting a series of the experimental data of the DBT HDS conversion over the catalysts with different support properties. Finally it has been shown that for the proposed model, the total average relative deviation was 1.43% and the prediction deviation was 2.21%.
