METHODS FOR PREPARING AND COLLECTING POLYAROMATIC COMPOUNDS, AND PRODUCTS COMPRISING POLYAROMATIC COMPOUNDS

摘要

Disclosed are methods for preparing and collecting a polyaromatic compoundcomprising a first subjecting step, wherein a first biomass is subjected to afirst fluidcomprising hot compressed water, thereby forming a first mixture; wherein thefirstmixture comprises a first liquid fraction comprising a first solubilizedpolyaromaticcompound; a first acidifying step, wherein a first liquid comprising the firstsolubilized polyaromatic compound is acidified at a temperature of at leastabout 90C, thereby forming a second mixture comprising a first precipitatedpolyaromaticcompound; and a first collecting step, wherein at least a portion of the firstprecipitated polyaromatic compound is collected, thereby obtaining a firstcollectedprecipitated polyaromatic compound; wherein a substantial portion of the firstcollected precipitated polyaromatic compound is not discarded. The collectedmaterial is employed in a variety of useful applications.
