METHOD OF SEPARATION OF HEMICELLULOSE FROM BIOMASS, CONTAINING HEMICELLULUS, AND ALSO BIOMASS AND HEMICELLULUS, OBTAINED BY THIS METHOD

摘要

A method for separating hemicellulose from biomass containing hemicellulose is described, which includes steps a) extracting hemicellulose from biomass containing hemicellulose by treating the complex with an aqueous solution to form a soluble hemicellulose complex, and b) separating hemicellulose as a complex from biomass. The method is particularly suitable for obtaining high-quality chemical pulp from cellulosic raw materials. In addition to the high purity of the obtained products of the method, the following advantage is the high efficiency of the method and small waste. Further, the method is characterized by the fact that, as a by-product, polymeric hemicellulose in pure form can be obtained. An international search report was published 2003.03.20.
