【摘要】：通过生物油蒸汽重整制备氢气可以减少环境污染,降低对化石燃料的依赖,是一种极具潜力的制氢途径。乙酸是生物油的主要成分之一,常作为模型化合物进行研究。镍基催化剂是乙酸蒸汽重整过程中常用的催化剂,但容易因积炭失去活性,降低了制氢过程的经济性。本文首先分析了影响乙酸蒸汽重整制氢过程的各种因素,阐述了在这一过程中镍基催化剂的积炭原理,讨论了优化镍基催化剂的方法,包括优化催化剂的预处理过程、添加助剂和选择合适的载体,最后对乙酸蒸汽重整制氢的热力学分析研究进展进行了总结。未来应重点研究多种助剂复合使用时对镍基催化剂积炭与活性的影响,分析多种助剂的协同作用机理,得到一种高活性、高抗积炭能力的用于生物油蒸汽重整制氢的镍基催化剂。
[Abstract]:Hydrogen production by steam reforming of bio-oil can reduce environmental pollution and reduce the dependence on fossil fuels. It is a promising way to produce hydrogen.Acetic acid is one of the major components of bio-oil and is often studied as a model compound.Nickel based catalyst is a common catalyst in acetic acid steam reforming process, but it is easy to lose activity due to carbon deposition, which reduces the economy of hydrogen production process.In this paper, the factors affecting the process of hydrogen production from steam reforming of acetic acid are analyzed, the principle of carbon deposition of nickel based catalyst is expounded, and the methods of optimizing nickel based catalyst, including the pretreatment process of catalyst, are discussed.Finally, the thermodynamic analysis of hydrogen production by steam reforming of acetic acid was summarized.In the future, we should focus on the influence of various additives on the carbon deposition and activity of nickel-based catalysts, analyze the synergistic mechanism of various additives, and obtain a kind of high activity.Nickel-based catalyst for hydrogen production from steam reforming of bio-oil with high resistance to carbon deposition.
