| Summary: | The photocatalytic oxidation of ethyl alcohol vapor in an annulus fluidized bed reactor of 0.06 m I.D. and1.0 m long was examined. The TiO2 catalyst employed was prepared by the sol-gel method and was coated on the silicagel powder. The UV lamp was installed at the center of the bed as the light source. The effects of the initial con-centration of ethyl alcohol, the power of UV-lamp, the photocatalysts with diferent preparation methods, and thesuperficial gas velocity on the reaction rate of ethyl alcohol decomposition were determined. It was found that, at 1.2Umf of flow rate, about 80% of ethyl alcohol was decomposed with initial concentration of 10,000 pmv and theincrease of superficial gas velocity reduced the reaction rate significantly.
