The conversion of bio‐based succinic acid (SA) to the value‐added chemicals 1,4‐butanediol (BDO), γ‐butyrolactone (GBL), and tetrahydrofuran (THF) can replace the corresponding petrochemical production routes to achieve a sustainable process. The reaction network for aqueous‐phase catalytic hydrogenation of succinic acid over a supported Re‐Pd catalyst was identified and the reaction kinetics was determined. With the developed kinetic model, the composition of the product mixture regarding the desired products (BDO, GBL, THF) can be described as a function of educt concentration, temperature, and pressure. The maximum BDO yield was achieved at high pressure and low temperature, while low pressure and high temperature favored GBL and THF production.

生物质琥珀酸的选择性加氢：反应网络和动力学
将生物基琥珀酸（SA）转化为增值化学品1,4-丁二醇（BDO），γ-丁内酯（GBL）和四氢呋喃（THF）可以替代相应的石化生产路线，以实现可持续发展的过程。确定了在负载型Re-Pd催化剂上进行琥珀酸水相催化加氢的反应网络，并确定了反应动力学。利用开发的动力学模型，可以将与所需产物（BDO，GBL，THF）有关的产物混合物的组成描述为离析物浓度，温度和压力的函数。在高压和低温下可获得最大的BDO产量，而低压和高温有利于GBL和THF的生产。
