Catalytic Conversion of Organosolv Lignins to Phenolic Monomers in Different Organic Solvents and Effect of Operating Conditions on Yield with Methyl Isobutyl Ketone
Catalytic depolymerization
of organosolv lignin to phenolic monomers with zeolites was investigated
under various operating conditions. H-USY (Si/Al molar ratio = 5)
outperformed H-USY with Si/Al ratios of 50 and 250, H-BEA, H-ZSM5,
and fumed SiO<sub>2</sub> to produce the highest phenolic monomer
yield from a commercial organosolv lignin in methanol at 300 °C
for 1 h. It was then further investigated in the presence of acetone,
ethyl acetate, methanol, and methyl isobutyl ketone (MIBK) on the
depolymerization of organosolv bagasse lignin (BGL). The total highest
phenolic monomer yield of 10.6 wt % was achieved with MIBK at 350
°C for 1 h with a catalyst loading of 10 wt %. A final total
phenolic monomer yield of 19.4 wt % was obtained with an initial H<sub>2</sub> pressure of 2 MPa under similar processing conditions. The
main phenolic monomers obtained are guaiacol (7.9 wt %), 4-ethylphenol
(6.0 wt %), and phenol (3.4 wt %). The solvent properties were used
to account for the differences in phenolic monomer yields obtained
with different organic solvents
