摘要

微藻水热液化生物油由于性质较差

不能直接作为车载燃料使用

与现代石油炼制工艺结合是一种新的应用途径。综述了微藻生物油的化学性质

包括化学组成、官能团组成与杂原子化合物组成等信息

比较分析了GC-MS、FTIR、NMR和FT-ICR MS等表征方法的异同

简要回顾了微藻水热液化反应机理和精制方法。重点指出微藻水热液化生物油中含氧、含氮化合物含量较高

并具有较高的芳香度和不饱和度

催化加氢精制能够有效脱除杂原子

并增加烷烃含量。微藻基生物燃料的发展

不仅需要精制工艺的提升

也有赖于表征方法的进步。

Abstract

Hydrothermal liquefaction (HTL) bio-crude from microalgae cannot be directly used as transportation fuels due to poor quality. A new approach for its application is integration of it and modern petroleum processing industry. The chemical properties of HTL bio-crude

including chemical composition

functional groups and heteroatom compounds constitution are summarized in this paper. The characterization methods including GC-MS

FTIR

NMR

FT-ICR MS were compared and analyzed. Formation mechanism and upgrading of HTL bio-crude were also briefly reviewed. The focus is on higher oxygenated and nitrogenous compounds content in HTL bio-crude

higher aromaticity and unsaturation degree comparing with heavy crude oil or residue oil. Catalytic hydrotreating could effectively remove heteroatom and increase hydrocarbon content. The development of microalgae-based bio-fuels depends on not only the progress in upgrading technique but also the improvement of characterization methods.
