Abstract: In a method for producing nanofibrillar cellulose, cellulose based fibre material, in which internal bonds in cellulose fibres have been weakened by 5 preliminary modification of cellulose, is subjected to disintegration treatment in form of pulp comprising fibres and liquid. The fibre material is supplied at a consistency higher than 10 wt-%, preferably at least 15 wt-%, to a disintegration treatment where fibrils are detached from the fibre material by joint effect of repeated impacts to the fibre material by fast moving 10 successive elements and the weakened internal bonds of the cellulose fibres. The nanofibrillar cellulose is withdrawn from the disintegration treatment at dry matter which is equal or higher than the consistency of the fibre material.

Abstract: In a method for producing nanofibrillar cellulose, cellulose based fiber material in dispersion is processed for separating fibrils. The method includes a first step where the fiber material is supplied to a disperser, where it flows through several counter-rotating rotors in such a way that the material is repeatedly subjected to shear and impact forces by the effect of the different counter-rotating rotors, and a second step, where the fiber material obtained from the first step is supplied to a homogenizer, where it is subjected to homogenization by the effect of pressure.

Abstract: A method and apparatus for enzymatic hydrolysis where a plant based feed is hydrolysed using an enzyme to form a hydrolysed product. An additive for preventing enzyme adsorption is fed to an enzymatic hydrolysis stage, the plant based feed the hydrolysed product a starting material, and/or a plant based material formed from the starting material. The hydrolysed product is supplied from the enzymatic hydrolysis stage to a first solid-liquid separation stage where a lignin fraction comprising the additive and a liquid composition comprising the enzyme are separated. The liquid composition is mixed with the plant based material in a mixing stage, forming a mixture. A solid fraction and liquid fraction are separated from the mixture in a second solid-liquid separation stage. At least part of the solid which comprises comprising the enzyme is fed as the plant based feed to the enzymatic hydrolysis stage.

Abstract: A method for making nanofibrillar cellulose includes mixing anionized or cationized cellulose fibers and cellulose pulp to a mixture including at least 1% and below 90 wt-% cellulose pulp based on dry weight, and subjecting the mixture to a refiner stage where the anionized or cationized cellulose fibers are at least partly reduced to nanofibrillar cellulose and the cellulose pulp acts as auxiliary pulp, and obtaining a mixture of nanofibrillar cellulose and cellulose pulp from the refining stage. The mixture can be used for making paper by adding it to base pulp.
