Products of direct liquefaction of biomass
Several methods of characterizing products of biomass liquefaction including GC-MS, wet analysis, infrared and various forms of liquid chromatography have been tried. Of these the SESC sequential elution technique has been particularly helpful in separating whole product oils into chemically distinguishable fractions. Variations in the distribution of SESC fractions have been used to show effects of changing conditions and changing feedstocks in biomass liquefaction. They have also been used to follow the effects of catalytic hydrogenation. Liquefaction of aspen results in higher yields than liquefaction of Douglas fir. The aspen oil product is richer in SESC fractions 1-4, is more fluid and has lower oxygen content. Catalytic hydrogenation is effective in increasing the percentage of oil in the more volatile SESC fractions 1-4.
