Abstract: Glycerol，the main by-product of biodiesel production process，is increased rapidly with the development of biodiesel industry. Production of high quality hydrogen from the aqueous phase reforming (APR) of glycerol is one of the main techniques to increase the added value of glycerol and reduce the cost of biodiesel production. In this review，the production of biodiesel and its by-product，glycerol，was introduced briefly，the concept of hydrogen production by the APR of glycerol was elaborated，and the effect on the APR of glycerol reaction was explained in detail in terms of both thermodynamics and dynamics. Especially，three aspects of the catalyst，the influence of precious metal，non-precious metal and supports on the APR of glycerol were summarized. It is proposed that the bimetallic catalyst may become a potential catalyst with high activity and high stability in APR reaction.

Key words: glycerol, hydrogen production, aqueous-phase reforming, catalyst

摘要： 甘油作为生物柴油的副产物，当前的产能严重过剩。甘油制氢，尤其是通过水相重整（APR）制取可以供燃料电池直接使用的高品质氢气，是提高甘油附加值、降低生物柴油成本的重要途径和手段。本文简述了当前生物柴油及其副产物甘油的生产，阐述了甘油的水相重整制氢反应，详细介绍了甘油水相重整制氢反应的热力学和动力学影响因素。分别从催化剂的贵金属活性组分、非贵金属活性组分和载体等三方面对甘油水相重整制氢反应进行了详细的综述，最后提出了双金属催化剂可能具有优异的催化甘油水相重整制氢性能。
