The purpose of this study is to investigate compounds of tar in which are produced in a fluidized bed gasifier. The tar compounds (M.W<300) were identified by gas chromatograph mass spectrometer (GC/MS) and gas chromatograph (GC-FID). The results of field desorption mass spectrometry (FD-MS) of tar showed that m/z increased by 24 when adding aromatic-ring to polycyclic aromatic hydrocarbon (PAH). Also, it was found that m/z changed 26 in difference to the bonding position of aromatic-ring with PAH. By applying this law to Benzo[ghi]perylene (M.W. 276), it was found that main compounds of tar were PAH.
