摘　　要：水热炭是一种以生物质或其组分为原料,以水为溶剂和反应介质,在150~375℃和自生压力下,经水热反应得到的以碳为主体,含氧官能团丰富,热值（HHV）高的黑色固体产物。水热炭的性质主要受原料种类、反应温度和时间的影响。水热炭在吸附、多孔炭制备、催化剂载体和清洁能源等领域展现出了良好的应用前景。本文综述了水热炭的制备、性质和形成机理,并对水热炭的应用进行了总结,对水热炭未来的发展方向进行了展望。Hydrochar is a black carbonaceous solid which is derived from biomass via hydrothermal carbonization condition：using water as solvent and reaction medium,at the temperature of 150 ~ 375℃ and autogenously pressure.Rich oxygen-containing functional groups,together with high heat value（HHV） are the distinguished properties of hydrochar.Their properties are influenced by raw materials type,hydrothermal carbonization temperature and time.It has revealed a promising perspective in absorbent,preparation of porous carbon,catalyst carrier and clean energy.In this study,the production,properties and formation mechanism of hydrochar are summarized.Meanwhile,the applications of hydrochar are reviewed and the future development is prospected.
