Abstract
A novel system of fast pyrolysis and vapour quenching was developed
at pilot scale to obtain bio-oil from biomass. The system uses three-stage of interconnected fluidized bed
reactors that continuously circulate silica sand from an internal pyrolysis
reactor to a second external annular reactor for char burning, which generates
most of the heat required by the pyrolysis reactor, and a third sand-preheating
reactor that burns non-condensable pyrolysis gas. The hot vapours, after high
temperature cleaning, are quenched in a flash cooling system. The process generates up to 62% of bio-oil, 25%
of char and 13% of non-condensable gas. The heat requirements for the total
system are provided by
burning part of the char and non-condensable gases generated in the pyrolysis
step and by preheating the fluidizing gas for the pyrolysis reactor.
