摘要/Abstract

摘要： 分析了不同原料制备的生物油含氧化合物的组成差异，综述了生物油中典型含氧化合物（酚类化合物、呋喃类化合物、醚类化合物、酸类和酯类化合物）的加氢脱氧机理，重点介绍了含氧化合物加氢脱氧动力学数据及反应路径；同时，还对生物油加氢精制过程进行了描述，主要论述了生物油加氢精制过程的机制以及O、S、N等杂原子在不同催化剂下的脱除活性；最后指出生物油加氢精制面临的问题是人们对其反应机理了解不够深入，而模型化合物加氢脱氧无法真实反映生物油的反应过程，今后应重点研究不同类型含氧化合物的相互作用和真实生物油的反应机理。

Abstract: The differences in the composition of the oxygenated compounds in bio-oil prepared by different biomass were presented. Then the reaction mechanisms of hydrodeoxygenation(HDO) of the main oxygenated compounds(phenols,furans,ethers,acids and esters) were reviewed,and the HDO kinetic data and reaction pathways were described in detail. Meanwhile,the HDO reaction processes of real bio-oil feeds were sketched,and the removal activities of heteroatoms O,N,S catalyzed by different catalysts were also discussed. Moreover,the problem of the hydrotreating of bio-oil was pointed out that we know little about the reaction mechanism of real bio-oil,and the HDO of model compounds can not reflect the reaction process of real bio-oil,thus the interaction of different types of oxygenated compounds and the reaction mechanism of real bio-oil should emphasically be studied.

Key words: bio-oils, oxygenated compound, hydrodeoxygenation, reaction kinetics, reaction pathway
