METHOD OF PRODUCING CELLULOSE Russian patent published in 2019 - IPC D21C3/00 D21C1/06 

FIELD: pulp and paper production.

SUBSTANCE: invention can be used in preparation of cellulose from non-woody annual plant material. Method of producing cellulose includes crushing and cleaning of cellulose-containing material, alkaline boiling, thermo-mechanochemical activation of cellulose-containing material, washing, bleaching, washing and drying. Thermomechanical activation is carried out outside the cooking vessel continuously in a return flow using an ultrasonic device and / or a device of ferromagnetic bodies rotating under the action of an electromagnetic field.

EFFECT: using the method allows to reduce the process time by reducing the alkafide process time.
