Daekyung Esco provided experimental data obtained from a
pilot-scale EFB plant of 2 ton-dry EFB/day. EFB was ground into
1–2 mm particles and was fed into the fast pyrolysis reactor
(fluidized-bed) kept at 450–550 C. The heating rate was about
1 104 C/min. The residence time of EFB was about 1.5 s inside
the fluidized-bed. The compressed air velocity of the fluidizedbed
was kept at 1.6 times of the minimum fluidization velocity.
The composition of the three products is given in Table 2 at three
different temperatures. The best biooil yield (60 wt%) including
water was achieved at 500 C in the pyrolysis reactor. The biooil
yield excluding water was 35 wt% in this plant. The char separated
from the cyclones was withdrawn and its yield was 24 wt%. The
similar results of the pyrolysis yield were achieved by Kim et al.
(2013), which were biooil of 36.6 wt%, water of 17.4 wt%, gas of
17.1 wt%, and char of 28.9 wt% [21]. Since the combustion of char
was not integrated in this pilot plant, the exterior heat was supplied
to the pyrolysis reactor.
