Abstract: The present invention describes a process for quenching a hydrothermal, dilute acid hydrolysis reaction of a biomass feedstock, wherein degradation of an aqueous monomer and/or oligomer sugar mixture is slowed down or stopped by flash cooling of the aqueous monomer and/or oligomer sugar mixture, and wherein the flash cooling ensures that a fraction of dissolved and volatile degradation byproducts are removed by a forming vapor stream, and wherein a lignin component, if present, is solidified into a structure with good de-watering characteristics, allowing for subsequent removal of the lignin component by separation, said process resulting in a hydrolyzed solution of sugar monomers and/or oligomers.

Abstract: The present invention relates to regulation of the p H of a liquefaction process. Presented is a method for treatment of a biomass feedstock wherein the biomass feedstock is subjected to liquefaction, at a p H of at most 4, by treatment with hot compressed liquid water (HCW) at subcritical and/or supercritical conditions to improve the conversion efficiency. The present invention is also directed to quenching of a liquefaction process according to above, preventing, minimizing or eliminating clogging and/or fouling of sticky biomass components in process equipment during processing as according to above, and to the use of additives in a biomass liquefaction process.
