Abstract
|
|
|
The photocatalytic decomposition characteristics of toluene, acetone, and methyl mercaptan (MM) by UV reactor installed
with TiO2-coated perforated plane were studied. The removal efficiency of single toluene, acetone, and MM vapor was
increased with increasing oxygen concentration, but decreased with increasing inlet concentration. Elimination capacity of
single toluene, acetone, and MM vapor was obtained to be 628 g/m3?day, 1,041 g/m3?day, and 2,158 g/m3?day, respectively.
Also, the photocatalytic decomposition of binary vapor consisted of toluene and acetone, toluene and MM, acetone and MM were observed. Elimination capacity of toluene mixed with acetone, toluene mixed with MM, acetone mixed with toluene,acetone mixed with MM, MM mixed with toluene, and MM mixed with acetone was 327 g/m3?day, 512 g/m3
?day, 128 g/m3?day, 266 g/m3?day, 785 g/m3?day and 883 g/m3?day, respectively. The inhibitory effect of acetone was higher than MM in photocatalytic decomposition of toluene, the inhibitory effect of toluene was higher than MM photocatalytic decomposition of acetone, and the inhibitory effect of toluene was higher than acetone in photocatalytic decomposition of MM.
