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，由于可以通过甘油和葡萄糖的发酵来生产，因此它可以成为生物质精炼的重要组成部分。最近，选择赤藓糖醇作为在CeO2负载的Re催化剂上脱氧脱水和氢化(DODH + HG)的底物，并进行了动力学建模。在反应过程中，赤藓糖醇中伯-仲邻位OH基团的DODH + HG生成1,2-丁二醇，而1,2-丁二醇的连续DODH + HG生成正丁烷。与此相反，1,4-丁二醇的DODH+HG，作为赤藓糖醇中仲-仲邻位OH基团的产物DODH+HG形成，不进一步进行。此外，预计赤藓糖醇的 DODH + HG 建模将与更复杂的糖（即木糖醇和山梨醇）的 DODH + HG 中的产物分布的预测和解释相关联。
