Development of a Crotalaria juncea based biorefinery produce large quantity of waste glycerol after trans-esterification of the juncea seeds. This glycerol, after purification, is used as a substrate for producing succinic acid on a microbial route. Hydrogenation of this bio-refined succinic acid is carried out under high pressure in order to produce 1,4-butanediol (BDO) using a batch slurry reactor with cobalt supported ruthenium bimetallic catalysts, synthesized in-house. It is demonstrated that, using small amounts of ruthenium to cobalt increases the overall hydrogenation activity for the production of 1,4-butanediol. Hydrogenation reactions are carried out at various operating temperatures and pressures along with changes in the mixing ratios of ruthenium chloride and cobalt chloride hexahydrate, which are used to synthesize the catalyst. The Ru-Co bimetallic catalysts are characterized by XRD, FE-SEM and TGA. Concentrations of the hydrogenation product are analyzed using Gas chromatography-Mass spectrometry (GC-MS). Statistical analysis of the overall hydrogenation process is performed using a Box-Behnken Design (BBD).

使用双金属催化剂将生物精制琥珀酸液相加氢为1,4-丁二醇

猪屎豆种子的酯交换后，基于猪屎豆属的芥菜的生物精炼厂的生产会产生大量的废甘油。纯化后，该甘油用作在微生物途径上生产琥珀酸的底物。该生物精制琥珀酸的氢化反应是在高压下进行的，以使用内部合成的钴负载钌双金属催化剂的间歇淤浆反应器生产1,4-丁二醇（BDO）。已证明，使用少量钌钴可提高生产1,4-丁二醇的总氢化活性。氢化反应在各种操作温度和压力下进行，同时氯化钌和六水合氯化钴的混合比也发生变化，用于合成催化剂。Ru-Co双金属催化剂的特征在于XRD，FE-SEM和TGA。使用气相色谱-质谱法（GC-MS）分析氢化产物的浓度。使用Box-Behnken设计（BBD）对整个氢化过程进行统计分析。
