The purpose of this study was to investigate the characteristics of removal efficiency for aromatic hydrocarbons using a high-temperature fiber filter on a laboratory scale. The main elemental compositions of a high-temperature fiber filter are aluminium and silica, which can act as the catalysts. Benzene, toluene and o-xylene among aromatic hydrocarbons were used in this experiment. For 3㎝ thickness of fiber filter, these compounds were removed more than 90% at the face velocities of 3㎝/sec and 5㎝/sec above 450℃. For 4㎝ thickness of it, the removal efficiencies of these compounds were almost 90% from 400℃ at the same face velocities, suggesting that it may be due to increasing the contact time between the fiber filter and aromatic hydrocarbons. The pressure drop ranged from 22 to 48㎜H2O for 3㎝ thickness of fiber filter. However, for 4㎝ thickness of it, it was about two times(41-89㎜H2O) higher than that for 3㎝ fiber thickness.
