Abstract

The transformations of hemicelluloses, cellulose, and lignin isolated from peat and sawdust were studied under conditions of hydrothermal carbonization and torrefaction. The effect of heat-treatment temperature on the yield and composition of the resulting biochars was established. It is shown that the nature of the raw material and the heat-treatment method have a significant effect on the carbon efficiency of the thermochemical conversion of its components. Carbohydrate components of sawdust were converted to a lesser extent than similar components of peat. Mild heat-treatment conditions (below 300°C) had almost no effect on lignin.

水热炭化和焙烧条件下木屑和泥炭结构组分的转变

摘要

研究了在水热碳化和烘焙条件下从泥炭和锯末中分离出的半纤维素、纤维素和木质素的转化。建立了热处理温度对所得生物炭的产量和组成的影响。结果表明，原料的性质和热处理方法对其组分热化学转化的碳效率有显着影响。锯末的碳水化合物成分的转化程度低于泥炭的类似成分。温和的热处理条件（低于 300°C）对木质素几乎没有影响。
