摘要：
Where thermochemical liquefaction of lignocellulosic biomass is conducted using recirculated product oil as solvent, yields can be substantially increased by addition of a short chain alcohol reactant such as ethanol or methanol. A synergistic effect is thereby obtained where liquefaction is improved over using either recycled product oil or alcohol alone. The combination of re-circulated product oil and alcohol reactant permits high onversion at operating pressures considerably lower than typically applied in alcohol solvolysis, typically within the range 30-60 bar. The liquefaction reaction occurs at subcritical pressure where the alcohol acts as a gaseous reactant and not as a solvent.
