Abstract:
Low-quality lumber yields little to no revenue, which gives a strong incentive to increase its market value. This study investigates the bio-crude yield, chemical composition, and energy content of bio-crudes obtained through formic acid-assisted hydrothermal liquefaction, focusing on the effects of lumber quality. The bio-crude yield ranges from 49-60 m%, with an HHV of approximately 35 MJ/kg. The influence of lumber quality on yield is found to be insignificant. GC-MS analysis reveals that the bio-crude is composed of alcohols, furans, and phenols, with their relative abundances being temperature dependent. Under ideal process conditions, the chemical composition of the bio-crude is found to be independent of lumber quality within the examined range. Thus, utilizing low-quality wood as a feedstock for HTL offers an advantage due to the significant price disparity in the market. In 2022, the market price for high-quality lumber in Norway was reported to be 2.7 times higher than that of low-quality lumber.
