First Claim
Patent Images
1. A process for liquefying a cellulosic material to produce a liquefied product, which process comprises contacting the cellulosic material simultaneously with(a) an acid catalyst;
- (b) a solvent mixture containing water and a co-solvent, which co-solvent comprises one or more polar solvents and which co-solvent is present in an amount of more than or equal to 10% by weight and less than or equal to 95% by weight, based on the total weight of water and co-solvent;
(c) a hydrogenation catalyst; and
(d) a source of hydrogen.

8. A product comprising:
-
(a) from 20 to 80 wt % of a monomeric fraction containing one or more monomeric compounds having a molecular weight (Mw) of less than or equal to 250 Dalton (Da); (b) from 20 to 80 wt % of an oligomeric fraction containing one or more oligomeric compounds having a molecular weight (Mw) of more than 250 Dalton (Da), wherein the percentage of saturated carbon atoms in the oligomeric fraction is more than or equal to 35%, based on the total amount of carbon atoms present. - View Dependent Claims (9, 10, 11, 12)

13. A process for producing a biofuel component from a cellulosic material, which process comprises
(a) contacting the cellulosic material simultaneously with an acid catalyst, a solvent mixture containing water and a co-solvent comprising one or more polar solvents, a hydrogenation catalyst and a source of hydrogen to produce a liquefied product; -
(b) obtaining one or more monomeric compounds and/or one or more oligomeric compounds from the liquefied product obtained in step a) to produce a second product comprising one or more monomeric compounds and/or one or more oligomeric compounds; (c) hydrodeoxygenating and/or cracking at least a part of the second product obtained in step b) to produce a fuel component and/or fuel component precursor; (d) blending and/or processing the fuel component and/or the fuel component precursor to a biofuel. - View Dependent Claims (14, 15, 16)
