摘要

本研究涉及通过创造资源节约型的方法来解决农业残留物的合理利用问题，使其有效转化为增值产品。麦草被用于这项工作的化学加工。使用甲酸/乙酸混合物进行处理。从而获得纤维素浆。用废溶液沉淀木质素。对木质素的结构进行了研究。结果表明，甲酸/乙酸处理对麦秆中纤维素的分离和木质素的回收具有较好的效果。小麦纤维素是一种很有前景的造纸纤维材料。小麦木质素可以作为制备生物吸附剂的材料。

Feasible Technology for Agricultural Residues Utilization for the Obtaining of Value-Added Products

The research is connected with the solving the problem of rational utilization of agricultural residues by the creation of resource-saving method for their efficient conversion into value-added products. Wheat straw was used in this work in chemical processing. Treatment was carried out with the application of formic/acetic acid mixture. Thus, cellulosic pulp was obtained. The spent solution was used to precipitate lignin. The structure of lignin was investigated. The results indicated that formic/acetic acid treatment was quite effective in isolating cellulose from wheat straw and in recovering lignin. Wheat cellulose is a promising fibrous material for the application in paper industry. Wheat lignin can be considered as a material for biosorbent preparation.
