FIELD: chemistry. ^ SUBSTANCE: method involves a) chemical treatment of substance containing lignocellulose through an oxidative system which contains at least one non-enzymatic oxidising agent and an activator at pH ranging from approximately 2 to approximately 6.5 and b) mechanical treatment of the substance containing lignocellulose during a period time sufficient for obtaining high alpha-cellulose pulp, where the lignocellulose-containing substance is chemically treated before and/or during any stage for mechanical treatment, and where the lignocellulose-containing substance is not chemically treated at pH ranging from approximately 11.5 to approximately 14 between stages a) and b). ^ EFFECT: reduced energy consumption, simplification of the method without need for considerable capital investments and improved quality of the end product. ^ 15 cl, 8 dwg, 6 ex, 6 tbl |
