Abstract:
The present invention provides for a process for producing dry, water-dispersible, non-surface modified nanocellulose particles or a powderous composition r comprising said particles comprising the steps of: i. providing a first suspension of non-surface modified cellulose particles in an first aqueous liquid, which aqueous liquid is non-solubilizing for the non-surface modified nanocellulose particles, ii. exchanging substantially all of the first aqueous liquid of the first suspension for a second solvent, which is miscible with the first aqueous liquid and non-solubilizing for the non-surface modified nanocellulose particles, to form a second suspension of non-surface modified nanocellulose particles in said second solvent, iii. contacting a flow of the second suspension of non-surface modified nanocellulose particles with a flow of a fluid in a supercritical or critical state, which fluid in a supercritical or critical state is miscible with the second solvent and non-solvating for the non-surface modified nanocellulose particles under conditions suitable for the transfer of substantially all of the second solvent into the supercritical fluid, iv. removing the second solvent and the fluid in a supercritical or critical state, preferably by controlling pressure and/or temperature, to form the dry, water-dispersible nanocellulose particles, v. collecting the dry, water-dispersible, non-surface modified nanocellulose particles and/or forming the powderous composition comprising said particles.

Claim (Index 6):
The process according to  claim 1 , wherein in the step of contacting the flow of the second suspension of non-surface modified nanocellulose particles with the flow of the fluid in a supercritical or critical state the mass flow ratio between the second suspension and the fluid in a supercritical or critical state is in the range of 1:10000 to 3:10.
