摘　　要：随着全球能源需求的快速增长和环境与可持续发展问题的日益突出,生物质资源作为化石能源的补充受到了广泛关注。通过快速热解技术,将生物质资源转化为同时具有经济和环境效益的液体生物油备受重视。然而,通过直接热解得到的生物油存在化学组分繁多、产率低、品质差等问题。在快速热解之前对生物质进行酸处理,可以有效去除生物质中碱/碱土金属元素(AAEMs)含量,显著改变生物质的形貌结构,极大改善生物油产品的组分分布,增加如左旋葡聚糖等高附加值化合物的产率,有效提升生物油品质,更有利于生物油的分离提纯和后期的高值化利用。总结分析了国内外学者对生物质进行不同酸处理后的热解研究现状,讨论了酸处理及联合酸处理对生物质形貌结构、AAEMs含量、热解过程及热解生物油的影响,为生物质资源化利用和转化提供了思路,对生物质热解酸处理技术的研究和改进提供了参考。With the rapid increase of global energy demand and the increasing prominence of environmental and sustainable development issues,biomass resources have received extensive attention as a supplement to fossil energy.The conversion of biomass resources into liquid bio-oil with both economic and environmental benefits through rapid pyrolysis technology has attracted much attention.However,the bio-oil obtained by direct pyrolysis has problems such as a wide variety of chemical components,low yield and poor quality.Acid treatment of biomass before rapid pyrolysis can effectively reduce the content of alkali/alkaline earth metal elements(AAEMs)in biomass,significantly change the morphology of biomass,greatly improve the component distribution of bio-oil products,increase the yield of high value-added compounds such as L-dextran,effectively improve the quality of bio-oil,and be more conducive to the separation and purification of bio-oil and high-value utilization in the later stage.This paper analyzes the research status of pyrolysis of biomass after different acid treatment d,discusses the effects of acid treatment and combined acid treatment on the morphology,AAEMs content,pyrolysis process and pyrolysis bio-oil of biomass,provides ideas for the utilization and transformation of biomass resources,and provides a reference for the research and improvement of biomass pyrolysis acid treatment technology.
