Abstract
Methods are disclosed for processing biomass by single-stage supercritical hydrolysis, wherein the biomass has been size reduced.
Claims27
A method, comprising:
- size reducing a starting lignocellulosic biomass to form a lignocellulosic biomass having a particle size less than about 500 μm;
- forming a mixture comprising:
- water;
- and
- said lignocellulosic biomass having a particle size less than about 500 μm;
- and
- contacting water at a temperature of at least about 374° C. and a pressure of at least about 221 bar with said mixture for a duration sufficient to produce at least one C5 or C6 saccharide;
- wherein said mixture is substantially free of exogenous acid.
5 more elements
A composition, comprising:
- about 0.1% by weight to about 4% by weight, based on the total weight of the composition, of C5 monosaccharide;
- about 0.1% by weight to about 4% by weight, based on the total weight of the composition, of C5 oligosaccharide having a degree of polymerization less than about 15;
- about 0.1% by weight to about 8% by weight, based on the total weight of the composition, of C6 monosaccharide;
- and
- about 0.1% by weight to about 8% by weight, based on the total weight of the composition, of C6 oligosaccharide having a degree of polymerization less than about 15.
