METHOD OF PRODUCING CELLULOSE Russian patent published in 2019 - IPC D21C5/00

Abstract RU 2677063 C1

FIELD: pulp industry.

SUBSTANCE: invention relates to the field of pulp and paper production, can be used to obtain cellulose from non-wood 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 alkafide process vessel continuously in a return flow using a mechanical processing device.

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