The present invention relates to a process for purifying, such as salt/ion depletion, and/or ash reduction, and/or sulphur removal, and/or free sugar depletion, and/or VOC depletion or fractionating, preferably by using dewatering, of a slurry comprising a lignin or lignin derivative or a combination thereof. A lignin or lignin derivative obtainable from said process and uses thereof are also disclosed.

Method of purifying lignin by subjecting a slurry comprising lignin to an electric field

The present invention relates to a process for purifying a slurry comprising cellulose, such as microfibrillated cellulose, wherein the process comprises the following steps: &#x2014;providing a slurry comprising cellulose and liquid, &#x2014;subjecting the slurry to an electric field inducing the liquid of the slurry to flow, &#x2014;separating the liquid from the cellulose thus obtaining a liquid depleted slurry, &#x2014;adding a washing liquid, such as an organic solvent, to the liquid depleted slurry&#x2014;subjecting the liquid depleted slurry to an electric field inducing the washing liquid of the slurry to flow and&#x2014;separating the washing liquid from the cellulose, thus obtaining a purified cellulose. The invention also relates to cellulose such as microfibrillated cellulose obtainable from said process.

Process for treating cellulose and cellulose treated according to the process

The present invention relates to a process for dewatering a slurry comprising microfibrillated cellulose wherein the process comprises the following steps of, providing a slurry comprising microfibrillated cellulose and liquid, subjecting the slurry to an electric field inducing the liquid of the slurry to flow and separating the liquid from the microfibrillated cellulose. The invention also relates to microfibrillated cellulose dewatered according to the process.

Process for treating microfibrillated cellulose and microfibrillated cellulose treated according to the process
