柴油水蒸气催化脱硫精制的动力学研究

建立了可以用于预测水蒸气催化脱硫精制柴油实验结果的四集总反应动力学模型。该模型能够给定原料柴油的脱硫转化率、柴油的收率和汽油的收率，并能选取最佳操作条件。通过对实验数据的处理，得到了该模型的反应级数、速率常数、表观活化能以及催化剂失活因子等参数。结果表明，在温度不是太高的情况下，预测值与实验值有良好的吻合；不同性质的柴油应具有不同的模型参数；高温阶段预测的结果外推能力较差。

Kinetics research of diesel desulfurization refining technology with vapour on catalyst

A tetra-lumping kinetics model used to forecast the experimental results of diesel desulfurization refining technology with vapor was built after further analyzing the reaction mechanism of the method. The desulfurization conversion of the feedstock diesel, diesel yield and gasoline yield can be got, and the optimum operation parameters can be chosen by the model. According to experimental results, the model parameters, such as the order of reaction, the rate constants, the apparent activation energy and the inactivation factor of catalyst were obtained. The calculated results agree with the experiment ones very well on condition that the temperature is not very high. There are different model parameters for different diesel. There are the poor prediction results under higher temperature.
