摘要

在德国哥廷根HAWK(Hochschule für Angewandte Wissenschaft und Kunst)测定了13个nitens桉树木材样品的总热值和净热值。在13个样品中,12个是热改性的,1个是未改性的。使用炸弹量热计测定样品的热值,Wentzel等人已经分析了木材成分(纤维素、半纤维素、木质素和提取物)。(2019)。在确定这些值后,R studio对样品进行统计分析,以找出热值、温度和木材成分之间的关系。发现未处理的nitens桉树样品的总热值和净热值分别为18.83MJ/kg和17.48MJ/kg,并且在热改性后,这些值增加到20.24MJ/kg和18.84MJ/kg。经过统计分析,木质素的结果与热处理温度和热值有很强的相关性。

Analysing the effect of thermal modification on the calorific values of Eucalyptus nitens wood
Gross and net calorific value of 13 samples of Eucalyptus nitens wood were determined at HAWK (Hochschule für Angewandte Wissenschaft und Kunst), Göttingen, Germany. Among 13 samples, 12 were thermally modified and one was unmodified. Calorific values of samples were determined by using a bomb calorimeter, and the wood components (cellulose, hemicellulose, lignin, and extractives) already analysed by Wentzel et al. (2019). After determination of the values, samples were statistically analysed by R studio to find the relations among the calorific value, temperature, and wood components. The gross calorific value and net calorific value of the untreated sample of Eucalyptus nitens were found to be 18.83 MJ/kg and 17.48 MJ/kg, and after thermal modification these increased up to 20.24 MJ/kg and 18.84 MJ/kg. Upon statistical analysis, the results for lignin showed a strong correlation with the temperature of thermal treatment and calorific value.
