摘要： Provided is a method comprising (a) providing a hydrolysis composition of at least 20 wt % of sugar equivalents, wherein the hydrolysis composition comprises a first oligosaccharide, water, optionally a soluble aromatic compound, (b) contacting the hydrolysis composition with a catalyst in a first reactor to hydrolyze at least a portion of the first oligosaccharide to form a first product composition comprising a first monosaccharide and a second oligosaccharide, (c) separating the first monosaccharide from the first product composition to form a second product composition comprising the second oligosaccharide, wherein at least a portion of the second oligosaccharide is a reversion sugar, and (d) converting via a further hydrolysis step at least a portion of the second oligosaccharide to form a third product composition comprising a second monosaccharide.

摘要： Vessels can be become fouled due to normal operation thereof, for example, during lignocellulosic biomass hydrolysis, and the vessel will become inoperable unless the fouling is removed from the vessel. Accordingly, methods are disclosed herein for removing fouling substances from the interior surfaces of fouled pressurized vessels. The methods utilize a brief rapid change of pressure in the vessel. In some embodiments, the rapid pressure change is a decrease, and the rapid pressure change causes, for example, increased velocity of the fluid flowing in the vessel, flashing of a portion of the fluid to vapor, and removal of the fouling substance adhered to the interior surface of the vessel.

摘要： Methods are disclosed for the continuous treatment of biomass comprising a pretreatment step, wherein said biomass is contacted with a first supercritical, near-critical, or sub-critical fluid to form a solid matrix and a first liquid fraction; and a hydrolysis step, wherein said solid matrix formed in said pretreatment step is contacted with a second supercritical or near-supercritical fluid to produce a second liquid fraction and an insoluble lignin-containing fraction. Also disclosed are apparatuses for the continuous conversion of biomass comprising a pretreatment reactor and a hydrolysis reactor associated with said pretreatment reactor.
