The pyrolysis of PKS was investigated to produce bio-oil in a
fluidized bed reactor. The higher feeding rate and higher gas
flow rate facilitated to enhance the bio-oil yield. The bio-oil
produced up to pyrolysis temperature 500 C formed two
distinct phases; however, they were in one homogeneous
phase when bio-oil was produced above this temperature. The
water content was reduced with increasing pyrolysis temperature.
The GCeMS data indicated that the peak area ration
of phenol is higher than any other detectable compound
evolved in the pyrolysis of PKS. The UVeFluorescence absorption,
which is the indication of aromatic content, was also
the highest for bio-oil produced at 550 C.
