Process for the processing of biomass containing cellulose, comprising the step of subjecting a treatment mixture comprising said biomass containing cellulose, water and sulfuric acid to a temperature in the range of 100 ° C to 220 ° C at a pressure in the range of 100 to 4000 kPa in which the pressure is selected such that, at least a part of the water is in a liquid state to generate a biomass containing treated cellulose, in which said treatment mixture further comprises one or more compounds of formula (I) ** Formula ** wherein in formula (I) R1 is selected from the group consisting of hydrogen and methyl R2 is selected from the group consisting of branched and unbranched alkyl having 9 to 22 atoms of carbon, each Rx in any of said groups x (II) ** Formula ** is, regardless of the meaning of Rx in the other groups (II), selected from the group consisting of hydrogen and methyl, x is a number integer from 3 to 40, and that it also comprises a step of saccharifying the biomass containing cellulose treated in such a way that glucose and / or other sugars are formed. |
