Processes for isolating xylose from an aqueous solution. A representative process can comprise providing an aqueous solution comprising xylose; combining a boron compound with the aqueous solution to form a boron derivative of the xylose; isolating the boron derivative of the xylose from the aqueous solution as a precipitate; dissolving the boron derivative of the xylose in a solvent; and isolating the xylose from the solvent as a precipitate using a boron capture agent.

Processes for isolation and recovery of C5 sugars

The presently disclosed subject matter relates to torrefied biomass briquettes and methods for producing the same that make use of a mixture of lightly torrefied material (LTM) and highly torrefied material (HTM) and/or make use of torrefied materials that are subjected to a hydrolysis pretreatment prior to being torrefied.

Torrefied biomass briquettes and related methods

Provided are processes for isolating hemicellulose-based sugar from a biomass. The process includes providing a biomass hydrolyzate including a C5 sugar, forming a boronic ester or diester of the C5 sugar, extracting the boronic ester of diester of the C5 sugar, precipitating the C5 sugar using a boron capture agent, and isolating the C5 sugar from the precipitate. The isolated C5 sugar is provided in dry form.
