摘　　要：生物质是一种极具应用潜力的可再生资源,具有来源广泛、储量丰富和价格低廉等特点。以生物质为原料制备活性炭,是推进生物质材料资源化利用的重要途径。本文主要综述了以生物质为原料制备活性炭以及通过制备条件调控其比表面积、孔隙结构和表面性质等微结构特性的研究,重点阐述了生物质组成、炭化和活化条件(如炭化方式、活化剂种类、活化剂用量及反应停留时间等因素)对活性炭微结构特性的影响,并对常用活化剂(如水蒸气、CO_(2)、ZnCl_(2)、H_(3)PO_(4)、KOH等)对孔结构和表面性质的调控机理进行了详细探讨。最后对具有不同微结构特性活性炭的应用做了总结。Biomass is a kind of renewable resource with great application potential,which has the characteristics of wide source,abundant reserves and low price.The preparation of biomass activated carbon is an important route to promote the resource utilization of biomass materials.In this paper,the preparation of activated carbon from biomass and the regulation of preparation conditions for its microstructural characteristics including specific surface area,pore structure and surface properties are reviewed.The effects of biomass composition,carbonization and activation conditions(such as carbonization method,activator type,activator dosage,and reaction residence time)on the microstructure characteristics of activated carbon are emphatically expounded.The regulation mechanism of pore structure and surface properties by common activators(such as water vapor,CO_(2),ZnCl_(2),H_(3)PO_(4),KOH,etc.)is discussed in detail.Finally,this paper summarizes the applications of activated carbon with different microstructure characteristics.
