FIELD: chemistry.
SUBSTANCE: invention relates to an integrated method of producing cellulose and at least one reusable low-molecular weight material. The method comprises preparing starting material containing lignocellulose and pulping using an alkaline treatment medium; from the pulped material, separating a cellulose-rich fraction and a cellulose-depleted fraction; subjecting the cellulose-depleted fraction to treatment using a method selected from a group comprising depolymerisation, hydrocracking, decarboxylation and a combination thereof; obtaining at least one reusable (secondary) low-molecular weight material selected from a group including, for example, hydrogen, aliphatic, cycloaliphatic, aromatic hydrocarbons and mixtures thereof, aromatic alcohols, aromatic aldehydes and mixtures thereof.
EFFECT: invention enables optimum integration of production of said end products, including additional reusable materials when producing cellulose.
