What is Toluene Removal from Indoor Air Using a Miniaturized Photocatalytic Air Purifier Including a Preceding Adsorption/desorption Unit about?
The performance of the miniaturized photocatalytic air purifier including a continuous adsorption/desorption unit with a zeolite particles-loaded honeycomb rotor was investigated in the photocatalytic purification of 1 m 3 air containing toluene at concentrations of 3-11 mg m -3 (about 1-3 ppmv). While operating the continuous adsorption/desorption unit only, and for desorption temperatures controlled within the range of 90-120 and 130-160 • C, the unit took approximately 10 min to reduce the toluene concentration in a 1 m 3 room, to a value of almost zero. Almost the same time courses of toluene concentrations were obtained when the photocatalytic reactor was switched on. This result clearly shows that the rapid decrease in the toluene concentration in the 1 m 3 room is mainly due to the adsorption of toluene onto the zeolite rotor. When the reactor was switched off, the concentration of toluene desorbed into the 0.022 m 3 reactor box increased rapidly and then levelled off in 10 min. On the other hand when the reactor was switched on, the toluene concentration in the reactor box increased rapidly, passing through a maximum in 10-150 min, and then decreasing to a value near zero,
