【摘要】：通過生物油蒸汽重整制備氫氣可以減少環(huán)境污染,降低對化石燃料的依賴,是一種極具潛力的制氫途徑。乙酸是生物油的主要成分之一,常作為模型化合物進(jìn)行研究。鎳基催化劑是乙酸蒸汽重整過程中常用的催化劑,但容易因積炭失去活性,降低了制氫過程的經(jīng)濟(jì)性。本文首先分析了影響乙酸蒸汽重整制氫過程的各種因素,闡述了在這一過程中鎳基催化劑的積炭原理,討論了優(yōu)化鎳基催化劑的方法,包括優(yōu)化催化劑的預(yù)處理過程、添加助劑和選擇合適的載體,最后對乙酸蒸汽重整制氫的熱力學(xué)分析研究進(jìn)展進(jìn)行了總結(jié)。未來應(yīng)重點(diǎn)研究多種助劑復(fù)合使用時(shí)對鎳基催化劑積炭與活性的影響,分析多種助劑的協(xié)同作用機(jī)理,得到一種高活性、高抗積炭能力的用于生物油蒸汽重整制氫的鎳基催化劑。
[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.
