This review covers the characteristics of pyrolysis and catalytic pyrolysis bio-oils by focusing on the fundamental factors that determine bio-oil upgradability. The abundant works on the subject of bio-oil production from lignocellulosic biomass were studied to establish the essential attributes of the bio-oils for assessment of the oil stability and upgradability. Bio-oils from catalytic pyrolysis processes relating to catalysts of different compositions and structures are discussed. A general relationship between the higher heating value and the oxygen content in the catalytic pyrolysis oils exists, but this relationship does not apply to the thermal pyrolysis oil. Reporting bio-oil yield is meaningful only when the oxygen content of the oil is measured because the pyrolytic oil stability is mainly determined by the oxygen content. Isoenergy plot that associates bio-oil yield with oxygen content is presented and discussed.
这篇综述重点关注决定生物油可升级性的基本因素，介绍了热解和催化热解生物油的特点。研究了大量关于从木质纤维素生物质生产生物油的相关文献，以确定生物油的基本特性，从而评估其稳定性和可升级性。本文还讨论了不同组成和结构的催化剂作用下，催化热解过程中产生的生物油。在催化热解油中，存在着高位热值与含氧量之间的一般关系，但这种关系并不适用于热解油。只有当测量油中的氧含量时，报告生物油产率才有意义，因为油的热稳定性主要取决于氧含量。本文还提出并讨论了一个与生物油产率与氧含量相关的等能量图。
