Today’s methods for producing powdered celluloses, in particular microcrystalline cellulose (MCC), from various plant raw materials, while applying new highly efficient methods for the isolation of cellulose are of a great interest. One of these methods is the production of MCC from lignocellulosic material activated by steam explosion treatment. The material obtained by this method from wood has a high reactivity, low content of residual lignin, a high specific surface, which allows to subject it successfully and efficiently to accelerated delignification or hydrolytic breakdown (degradation). This ability of the lignocellulosic material, activated by steam explosion, is the basis of this study, which provides the results of an experimental evaluation of the component and dispersion analysis of MCC, obtained from this material.
In this paper we present the results of a study of the physical and chemical properties of activated lignocellulose obtained in the process of steam explosion treatment of various breeds of wood. It is shown that fibrous material has a high potential for scientific and commercial use: in the field of production of pulp for paper and cardboard production in a more efficient way, to obtain microcrystalline cellulose by hydrolysis, to produce coarse lignocellulosic fibers for the production of construction and insulation boards with new properties. The scope of activated lignocellulose is not limited only to these directions, but can be significantly expanded due to the competent use of its physical and chemical properties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
