Deconstruction of lignocellulosic biomass to bio-oils with zieglar-natta catalyst in ethanol and water
Naijia Hao

L
ignocellulosic biomass (grape seeds) was deconstructed in
both hydrothermal and supercritical ethanol media with
Zieglar-Natta catalyst components (TiCl
4
/MgCl
2
) to produce
the bio-oils. The use of catalyst in the deconstruction in
supercritical ethanol achieved the highest bio-oil yield of
49.2% at 300 °C with a residence time of 30 min, which was
37.4% higher than the bio-oil yield obtained from the same
condition. Both the hydrothermal and supercritical ethanol
deconstruction reactions with the highest catalyst loading
(TiCl
4
/MgCl
2
=4mmol/4mmol) produced the bio-oils with a
higher heating value (HHV) of 35 MJ/Kg which was comparable
of the HHV of petroleum based liquid fuels. Most significantly,
gas chromatography–mass spectrometry (GC-MS) analysis
of the bio-oils showed that the major products in bio-oils
from the hydrothermal deconstruction were acids while
majority products in bio-oils form the supercritical ethanol
deconstruction were esters. 31P Nuclear magnetic resonance
(NMR) data suggested that both non-catalytic and catalytic
hydrothermal/supercritical ethanol deconstruction reactions
significantly reduced the C5 substituted phenolic OH in bio-oils.
