摘要: 由于生物柴油产业的蓬勃发展而造成副产物甘油的大量过剩,迫使人们努力寻求甘油转化为高附加价值产物的有效途径。本文综述了国内外甘油氢解制1,2-丙二醇催化剂以及机理研究的新进展。指出催化剂是甘油氢解制1,2-丙二醇的关键因素,目前甘油氢解反应中以Cu、Ni、Ru、Pt、Rh基催化剂使用较多,其中Cu基催化剂的研究最为广泛,载体、助剂、制备方法、反应溶剂、甘油氢解条件等对Cu基催化剂的活性、选择性、寿命、产物分离难度等具有较大影响。为进一步改善催化剂的综合性能,需要加强对甘油氢解机理和催化剂制备技术的基础性研究。多金属催化剂、复合多功能催化剂和甘油原位氢解反应因其自身优势颇受关注,而催化剂的失活机理及再生性能考察是值得深入研究的新课题。

Abstract: The huge surplus of by-product glycerol due to the rapid development of biodiesel industry, people were motivated to find a way to convert glycerol to high value-added chemicals. This review summarized the catalytics and mechanisms of the glycerol to 1,2-propanediol. Catalyst is the key factor in the hydrogenolysis of glycerol to 1,2-propanediol. At present, Cu, Ni, Ru, Pt, Rh-based catalysts are often used in hydrogenolysis of glycerol. Among them, Cu-based catalysts are the most widely studied. The activity, selectivity, stability of Cu-based catalysts, and product separation are affected by the supports, promoters, preparations, solvent and process conditions. To improve the performance of glycerol hydrogenolysis, it is necessary to strengthen the basic researches on the mechanism for hydrogenolysis of glycerol and catalyst preparation technologies. Composited metal catalysts, composite multifunctional catalysts and glycerol in situ hydrogenolysis had been received much attention due to their own advantages. The regeneration of catalyst and deactivation mechanism are new directions for the future researches.

Key words: glycerol, hydrogenolysis, 1,2-propanediol, catalyst, hydrogenation, support
