项目摘要

Erythritol is a typical C4 sugar alcohol, and it can be an important building block in biomass refinery because of a possibility of its production by fermentation of glycerol, as well as glucose. Recently, erythritol was selected as the substrate for the deoxydehydration and hydrogenation (DODH + HG) over CeO2 supported Re catalsyt, and the kinetic modelling had been conducted. During the reaction, DODH + HG of primary-secondary vicinal OH groups in erythritol gives 1,2-butanediol while the consecutive DODH + HG of 1,2-butanediol results in n-butane. Contrary to it DODH+HG of 1,4-butanediol, formed as a product DODH + HG of the secondary-secondary vicinal OH groups in erythritol, does not proceed further. Moreover, it is envisaged that in the modelling of DODH + HG of erythritol will be connected to the prediction and the interpretation of the product distribution in DODH+HG of more complex sugars, i.e. xylitol and sorbitol.
赤藓糖醇是一种典型的C4糖醇,由于其可以通过发酵甘油以及葡萄糖来生产,因此它可以是生物质精炼中的重要构件。最近,在CeO_2负载的Re催化剂上,选择铼作为脱氧脱水和氢化(DODH + HG)的底物,并进行了动力学模拟。在反应过程中,顺丁烯二醇中的伯-仲邻位OH的DODH + HG生成1,2-丁二醇,而1,2-丁二醇中的连续DODH + HG生成正丁烷。与此相反,1,4-丁二醇的DODH+HG,作为仲-仲邻位OH基团的产物DODH + HG形成于丁二醇中,不进一步进行。此外,设想在对D 0 DH + HG的建模中,将与更复杂的糖(即木糖醇和山梨糖醇)在D 0 DH +HG中的产物分布的预测和解释相关联。
