1. A method for producing a bio-oil from lignocellulosic matter, the method comprising the steps of:
- (a) solvating hemicellulose from the lignocellulosic matter using a solvent;
(b) removing solvated hemicellulose from solid matter comprising lignin and cellulose remaining after step (a); and
(c) solvating both of the lignin and the cellulose of the solid matter together using a solvent at a reaction temperature of between 260°
C. and 350°
C. and a reaction pressure of between 8 MPa and 26 MPa,wherein step (c) of solvating both of the lignin and the cellulose together at said reaction temperature and said reaction pressure converts the lignin and the cellulose into a product comprising an aqueous phase and an oil phase comprising the bio-oil; and
wherein the bio-oil is produced in the absence of fermentation or enzymatic hydrolysis of said lignocellulosic matter.

21. A method for producing a bio-oil from lignocellulosic matter, the method comprising the steps of:
-
(a) solvating hemicellulose from the lignocellulosic matter using a solvent; (b) removing solvated hemicellulose from solid matter remaining after step (a); and (c) solvating a slurry comprising between 2% and 45% solid matter by weight and comprising lignin and cellulose obtained from the material obtained in step (b) using a solvent at a reaction temperature of between 260°
C. and 350°
C. and a reaction pressure of between 8 MPa and 26 MPa to produce a bio-oil;wherein the lignin and cellulose are solvated together at said reaction pressure and temperature thereby converting the lignin and the cellulose into the bio-oil, and the method does not comprise enzymatic hydrolysis of cellulose to produce sugar units and fermentation of the sugar units by a microorganism to provide a bio-alcohol.
