The pyrolysis characteristic of furniture processing residue (FPR), which was analyzed by thermogravimetric analysis (TGA) under nitrogen atmosphere, mainly decomposed between 230 °C and 500 °C. The FPR was submitted to fast pyrolysis in a bubbling fluidized-bed reactor (BFR) for converting into bio-oil, bio-char. The product distribution and characteristics of bio-oil depend on the operating conditions (temperature, fluidizing flow rate, particle size of sample). The bio-oil yield showed the highest value (50.68 wt%) at the pyrolysis temperature of 450 °C with a biomass particle size of 1.0 mm and a fluidization velocity of 2.0×U mf . The bio-oil had high selectivity for dioctyl phthalate, levoglucosan, and phenolic derivatives. The carbon number proportions in bio-oils of FPR were 32.74 wt% for C 5 –C 11 fraction, 47.60 wt% for C 12 –C 18 fraction and 19.38 wt% of C 25 –C 38 fraction, respectively. The gas product included CO, CO 2 , H 2 , and hydrocarbons (C 1 –C 4 ), and the selectivity of CO 2 was the highest. The high heating value (HHV) of gas products was between 4.60 and 12.90 MJ/m 3 . The bio-char shows high HHV (23.87 MJ/kg) and high C content (62.47 wt%) that can be applied as a solid fuel.
