A numerical study describes the catalytic conversion of glucose into ethylene glycol (EG) in a semi‐batch reactor. This analysis couples a set of power law models (homogeneous reactions) and Langmuir‐Hinshelwood‐Hougen‐Watson (LHHW) equations (hydrogenations). For this purpose, the kinetic parameters of the LHHW expressions are estimated for the reaction conditions. Then, the kinetic model evaluates the influence of the H2 pressure and the catalyst concentrations on the selectivity. The results indicate that the EG yield is increased by setting the temperature and the H2 pressure. In this manner, the process reduces the hexitols and methane production and increases the EG yield. The originality of the work is based on the influence of the H2 pressure and the catalyst concentrations in the model.

半连续反应器中葡萄糖生产乙二醇的建模
一项数值研究描述了在半间歇式反应器中葡萄糖催化转化为乙二醇（EG）的过程。该分析耦合了一组幂律模型（均相反应）和Langmuir-Hinshelwood-Hougen-Watson（LHHW）方程（加氢）。为此目的，针对反应条件估计LHHW表达的动力学参数。然后，动力学模型评估H 2压力和催化剂浓度对选择性的影响。结果表明，通过设定温度和H 2压力，EG产率增加。以这种方式，该方法减少了己糖醇和甲烷的产生并增加了EG的产率。作品的原创性基于H 2的影响 模型中的压力和催化剂浓度。
