Beschreibung
Zusammenfassung:	The embodiments of the present disclosure provide a method for extracting xylose liquid and cellulose with high purity from corn straw. The method includes raw material screening, raw material preprocessing, alkali processing, acid hydrolysis, and gradient alkali processing. The embodiments of the present disclosure adopt a gradient selective refining method for extracting a high-purity xylose liquid and cellulose from the corn straw, so as to maximize the extraction of the xylose from the corn straw, and at the same time, to separate and extract a high-purity cellulose product from straw residue under a low-cost process processing.
