Fast Pyrolysis of Short Rotation Coppice Poplar: An Investigation in Thermochemical Conversion of a Realistic Feedstock for the Biorefinery
Short
rotation coppice (SRC) is a promising plantation system because
it provides inexpensive feedstock for biorefineries. This study investigated
the conversion of 2-year-old first rotation SRC poplar into bio-oil
via fast pyrolysis. The impact of leaf removal was studied by comparing
the yields and compositions of bio-oil from no-leaf coppice (NLC)
and whole tree coppice (WTC). Leaf removal did not affect the bio-oil
yield of SRC poplar samples (∼55%) but lowered the char yield
from 19.7% to 13.6% and increased the gas yield from 14.3% to 17.7%.
The chemical compositions of bio-oils, char, and noncondensable gases
obtained from WTC and NLC were different. Leaf removal changed the
elemental composition of the bio-oil. The bio-oil from WTC had higher
H (9.1%) and O (64.8%) but lower C (25.3%) than that from NLC. Consequently,
leaf removal increased the higher heating value (HHV) of bio-oil by
2.1 MJ/kg (16.0%). On the basis of the results of the current research
and our previous study, the energy recovery rate for producing liquid
fuel via fast pyrolysis of SRC poplar samples (29.4–34.2%)
is markedly higher than that obtained by biochemical conversion (15.6–25.5%)
