abstract = {This study adapts the biphasic OrganoCat system into a
flow-through (FT) reactor, using a heated tubular setup
where a mixture of oxalic acid and 2-methyltetrahydrofuran
(2-MTHF) is pumped through beech wood biomass. This method
minimizes solvent-biomass contact time, facilitating rapid
product removal and reducing the risk of secondary
reactions. A comparative analysis with traditional batch
processes reveals that the FT system, especially under
severe conditions, significantly enhances extraction
efficiency, yielding higher amounts of lignin and sugars
with reduced solid residue. Notably, the FT system doubles
the sugar yield under harsh conditions compared to the batch
process, with a slight increase in lignin yield, indicating
more efficient depolymerization of polysaccharides without
substantial sugar degradation. A statistical design of
experiments (DOE) using a Box-Behnken design elucidates the
influence of process variables (time, solvent flow rate,
temperature) on the yield. Key findings highlight reactor
temperature as the dominant factor affecting yields, with
process time showing a significant but less pronounced
impact. This study demonstrates the potential of the FT
OrganoCat system for efficient lignocellulosic biomass
fractionation and represents an advancement towards
continuous lignocellulose processing, contributing to our
knowledge of process optimization for improved biorefinery
applications.},
