Abstract

The boom of the biodiesel industry has led to an oversupply of by-product glycerol as a direct consequence, which has been detrimental to its market value. The chemical reactivity that this compound possesses makes it an exceptional building block from which many synthetic routes can originate. In the past two decades, as a way to upgrade glycerol, there have been great developments in experimental approaches to obtain different products with applications as fuel additives, green solvents or precursors to other materials. These works have focused mainly on the development of catalytic and biotechnological processes and optimization of operation conditions to obtain chemicals like glycerol carbonate, acetals, esters, ethers, 1,2- and 1,3-propanediol, acrolein, halogenated products and different organic acids. Throughout these years an increasing amount of articles have reported thermodynamic information and kinetic models for different reactions using glycerol of substrate, whose knowledge is essential for subsequent reactor and process design. For the first time, these aspects for transformation reactions from glycerol are compiled and presented in a systematic way in this comprehensive review that also touches on process intensification strategies to enhance glycerol conversion.

甘油转化为增值化学品:反应工程和动力学建模方面的最新技术和进展
生物柴油产业的蓬勃发展直接导致副产品甘油供过于求,从而损害了其市场价值。这种化合物所具有的化学反应活性使其成为一种特殊的构件,许多合成路线都可以从它出发。在过去的二十年里,作为一种升级甘油的方法,实验方法有了很大的发展,以获得不同的产品,用作燃料添加剂、绿色溶剂或其他材料的前体。这些工作主要集中在催化和生物技术工艺的开发以及操作条件的优化上,以获得碳酸甘油酯、乙醛、酯、醚、1,2- 和 1,3- 丙二醇、丙烯醛、卤化产品和不同有机酸等化学品。这些年来,越来越多的文章报道了以甘油为底物的不同反应的热力学信息和动力学模型,这些知识对于后续的反应器和工艺设计至关重要。本综述首次对甘油转化反应的这些方面进行了系统的汇编和介绍,同时还涉及了提高甘油转化率的工艺强化策略。

期刊介绍: Fuel Processing Technology (FPT) deals with the scientific and technological aspects of converting fossil and renewable resources to clean fuels, value-added chemicals, fuel-related advanced carbon materials and by-products. In addition to the traditional non-nuclear fossil fuels, biomass and wastes, papers on the integration of renewables such as solar and wind energy and energy storage into the fuel processing processes, as well as papers on the production and conversion of non-carbon-containing fuels such as hydrogen and ammonia, are also welcome. While chemical conversion is emphasized, papers on advanced physical conversion processes are also considered for publication in FPT. Papers on the fundamental aspects of fuel structure and properties will also be considered.
