TWO STEP OPTIMIZATION FOR LIQUEFACTION OF BIOMASS |
摘要 |
<p>The present invention describes a process involving liquefaction of a biomass slurry by treatment in hot compressed water (HCW), said process comprising:—a first decomposition step being performed at an average pH level of at most 4.5, wherein a hemicellulose fraction in the biomass slurry is decomposed to water soluble mono- and/or oligomers, and wherein a cellulose fraction undergoes a pre-treatment for decrystallization of the cellulose polymer;—a separation step; and—a second decomposition step, wherein the cellulose fraction in the biomass slurry is decomposed to water soluble mono- and/or oligomers; wherein both of the first and second decomposition steps are performed at sub-critical temperatures implying relatively moderate conditions.</p> |
