PROCESS FOR TREATING CELLULOSE AND CELLULOSE TREATED ACCORDING TO PROCESS Russian patent published in 2016 - IPC D21C9/06 

Abstract RU 2603957 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a method of purifying a slurry containing cellulose, such as microfibrillated cellulose, method comprising following steps: providing a slurry comprising cellulose and liquid, subjecting slurry to an electric field inducing liquid of slurry to flow, separating liquid from cellulose thus obtaining a liquid depleted slurry, adding a washing liquid, such as an organic solvent, to liquid depleted slurry, subjecting liquid depleted slurry to an electric field inducing washing liquid of slurry to flow, and separating washing liquid from cellulose, thus obtaining purified cellulose.

EFFECT: invention also relates to cellulose, such as microfibrillated cellulose obtained according to said method.
