Torrefaction is one of the methods of thermal treatment of biomass, which allows obtaining a product of better quality in the form of biochar. The aim of the paper was to analyze the possibility of using goldenrod , ) for the production of biochar. The torrefaction process involved the vegetative and generative parts as well as the whole plant at temperatures of 250 °C and 275 °C, for 3 h. Next, the physicochemical properties of the raw material and biochar were determined, namely moisture content, ash content, volatile matter content, calorific value, and heat of combustion. The bulk density of raw biomass and biochar was also determined. It was found that after biomass torrefaction, the ash content, calorific value, and heat of combustion increased, while volatile matter content decreased. It has been observed that in both the case of raw biomass and biochar, the plant species and the sampled parts have a significant impact on the ash content, volatile matter content, calorific value, and heat of combustion.
烘焙是生物质热处理的方法之一，它能够以生物炭的形式获得质量更好的产品。本文的目的是分析使用一枝黄花用于生产生物炭的可能性。烘焙过程涉及营养器官、生殖器官以及整株植物，在250℃和275℃的温度下进行3小时。接下来，测定了原材料和生物炭的物理化学性质，即水分含量、灰分含量、挥发物含量、热值和燃烧热。还测定了原始生物质和生物炭的堆积密度。结果发现，生物质烘焙后，灰分含量、热值和燃烧热增加，而挥发物含量降低。据观察，无论是原始生物质还是生物炭，植物种类和采样部位对灰分含量、挥发物含量、热值和燃烧热都有显著影响。
