This study analyzes the representative chemical compounds in bio-oil derived from pyrolysis of palm kernel shell with three particle sizes of 0.15-0.50, 0.50-1.00 and 1.00-2.00 mm. Fast pyrolysis was carried out in our newly designed fluidized bed reactor of 108 mm in internal diameter operated at 450 ℃ with nitrogen gas with flow rate of 21-25 L(NTP)/min. Vapor products from the pyrolyzer were collected by six successive condensers maintained at three temperatures; 28 (1st), 5 (2^<nd>) and -10 ℃ (the rest). The bio-oil yields in an ascending order of particle size were 19.2, 36.0 and 26.5 %, respectively. The compounds quantitatively analyzed in the bio-oils were acetic acid, phenol, furfural, 2-methylphenol, 4-methylphenol and 4-methylnaphthalene. Predominant effects to affect the bio-oil yield are discussed.
