摘要
生物炭是生物质在绝氧或限氧条件下热解的固态产物,通常因具有特殊的孔隙、官能团结构及稳定的物理化学性质等特点而广泛应用于气态或液态污染物的吸附,并成为目前生物质能资源化利用研究热点。本文介绍了生物质热解制取生物炭的工艺、生物炭生成机理及目前主要应用领域,重点评述了影响生物炭制备、结构特性及吸附特性的主要因素,并提出了生物质热解制备生物炭及其在吸附领域应用的未来研究方向。
Biochar is a solid product of biomass pyrolysis under anaerobic or oxygen-limited conditions.It is widely used in the adsorption of gaseous or liquid pollutants due to its special pore and functional group structure,and stable physicochemical properties.It has become a research hotspot of resource utilization of biomass energy.This paper introduced the preparation process of biochar by biomass pyrolysis,generation mechanism of biochar and current application fields.It focused on the main influence factors of preparation,structural characteristics and adsorbed characteristics of biochar,and it proposed the future research directions of biomass pyrolysis producing biochar and its application in the adsorption field.
