摘要:丁二酸二乙酯(SE)在Cu基催化剂上气相加氢可获得1,4-丁二醇(BD),γ-丁内酯(BL)及四氢呋喃(THF)三种重要产品。本文采用Cu基催化剂,在连续流动管式固定床反应器中,研究了SE气相加氢反应本征动力学。得到了该反应的网络。根据这一网络,建立了SE加氢体系的幂级数动力学模型。在200~230℃,1.90~3.92MPa,H_2:SE=100:1(mol)的条件下,考察了反应温度和氢气压力对反应速率的影响,求取了动力学参数。模型验证结果表明:模型对实验数据的拟合是有效的。
1,4-Butanediol(BD), y-butyrolactone(BL) and tetrahydrofuran(THF) are three important products which can be obtained by the gas phase hydrogenation of diethyl succinate (SE) over Cu-based catalyst. The intrinsic kinetics study of the gas phase hydrogenation of SE over a Cu-based catalyst was performed in a continuous flow fixed bed reactor. From the experimental results, a reaction scheme (see p.350) was established. Based on the reaction scheme, the power order kinetic model was established. Under the conditions of 200-230℃, hydrogen pressure 1,96-3.92 MPa and molar ratio of H2 to SE 100 = 1, the influence of reaction temperature and hydrogen pressure on the reaction rates was investigated, and the kinetic parameters were estimated by non-linear regression. The result of verification of the kinetic model showed that the kinetic model fitted the experimental data closely.
