报告摘要：

生物质水分和氧含量较高，热值和能量密度低，不宜长距离运输和长期储存，给后续转化利用带来问题。生物质烘焙是在低温，缺氧和低加热速率条件下的一种生物质处理技术。烘焙不仅改善生物质理化特性，还能提升其热化学转化性能。生物质烘焙动力学和热化学机理研究是生物质烘焙系统设计、过程优化及工业化应用的基础。将重点展示课题组生物质烘焙动力学及热化学方面的研究成果。

TITLE： Kinetics and Thermochemistry of Biomass Torrefaction

ABSTRACT：

    The direct use of lignocellulosic biomass (e.g., agricultural and forest residues) as fuel is inefficient because of its poor energy efficiency (e.g., low heating value, high moisture content, hygroscopic nature, low density and polymorphism, and high during transportation, handling and storage costs). Besides improving physicochemical properties of biomass, torrefaction can also improve its thermal conversional performance. The kinetics of biomass torrefaction is fundamental for the prediction of thermal decomposition kinetic characteristics under different torrefaction conditions and is helpful for the design, scale-up, optimization and industrial application of torrefaction processes/systems. The kinetic and thermochemical models for woody biomass torrefaction will be presented and discussed.
