Abstract:	The effects of gas velocity, annulus gap on solid (ε_s) and gas phase holdups (ε_g), UV light transmittance and photocatalytic reduction of TCE (trichloroethylene) over TiO₂/silica gel photocatalyst have been determined in an annulus fluidized bed photoreactor. The optimum TCE reduction efficiency exhibits at ε_s/ε_g of 0.48, annulus gap of 8 mm and UV light transmittance around 0.20. The most pronounced effects on TCE conversion are found to be gas velocity (U_g) and annular gap in the photoreactor.

Keywords:	Gas Velocity Annulus Gap Annulus-fluidized Bed TCE Reduction
