Abstract:

It is important to determine accurately the content of cellulose, hemicellulose and lignin in biomass.Based on element analysis and lumped model compound, a quick and convenient analysis method that can determine the content of main chemical components in biomass was proposed and nine kinds of biomass were tested.The agreement between calculated values and experimental values obtained by conventional chemical method was good, the error was in 10%.

摘要： 生物质中纤维素、半纤维素和木质素含量的准确分析对于生物质的利用很重要。基于元素分析和集总模型化合物，提出了一种快速、简便分析生物质中主要化学成分含量的方法，并将这种方法用于分析九种不同类型生物质中主要成分的含量。结果发现九种生物质主要成分含量的计算结果与化学方法得到的结果符合良好，分析误差在10%以内。
