Abstract
VTT is developing integrated fast pyrolysis, where production of bio-oil
is coupled to a fluidized-bed boiler plant. The arrangement has lower capital
and operation cost compared to stand-alone pyrolysis facilities. This paper
presents some of the experimental results obtained during the work. The
current challenge is to find an industrial site, where operation at larger
scale may be verified.
For the applications, experimental data was generated related to the
specific feedstock and taking into consideration liquid product properties.
Industrial wood waste, forest residues, wheat straw, reed canary grass,
timothy hay, eucalyptus chips, and pine sawdust (a reference material) were
pyrolysed. High yields of organic liquid were received from wood feedstock
with relatively low ash content, whereas annual crops with high ash content
yield considerable lower amounts of organics. However, due to the integration
of pyrolysis to a boiler, the overall economics of the system developed is
much less sensitive to reduced yields of organics than stand-alone pyrolysis
plants. The reason for this is that material not converted to bio-oil will be
replacing fuel in the main boiler.
Economic assessments generated in the project have been attractive,
and further development of the concept is being pursued. This may take place
at an existing fluidized-bed boiler, where enough space is available to locate
the pyrolysis reactor close to the main boiler, or at a new boiler site.
