摘要

当前研究的主要目的是确定木材加工工业、水果和葡萄种植活动以及绿地维护中产生的典型木质纤维素残留物的化学结构。分析了木屑、树皮、树木修剪和水果木质素化残留物等四组特征样品的灰分、亲脂和亲水提取物、纤维素、半纤维素和木质素的含量。用重量法分析,用红外光谱法检测分离组分的纯度。树皮和树木修剪中灰分和低分子量萃取物的含量最高,而木屑样品中纤维素和总碳水化合物的含量最高。木质素化的果实残渣和树皮被证明是木质素的丰富来源。由于其不同的化学成分,所有被检测的材料都是生物炼制过程中生产平台化学品和其他特定产品的潜在原料。

Kemijska sestava in potencialna uporabnost lignoceluloznih ostankov
The main purpose of the current research was to determine the chemical structure of typical lignocellulosic residues generated in wood processing industries, fruit and vine growing activities, and the maintenance of green areas. Four characteristic groups of samples, e.g. wood sawdust, bark, tree prunings and the lignified residues of fruits were analysed for the content of ash, lipophilic and hydrophilic extractives, cellulose, hemicellulose and lignin. Gravimetric methods were used for the analyses, and the purity of individual isolated fractions was monitored by FTIR spectroscopy. The highest quantity of ash and low molecular weight extractive compounds was determined in bark and tree prunings, while concentrations of cellulose and total carbohydrates were highest in sawdust samples. Lignified fruit residues and bark proved to be rich sources of lignin. Because of their diverse chemical composition, all of the examined materials are potential feedstocks for the production of platform chemicals and other specific products within biorefinery processes.
