ABSTRACT: We have investigated in this study the destruction
of acetone and toluene with AL-KO PURE air purifier (AL-KO PURE) on industrial scale.
In the case of acetone, 100% pollutant abatement is achieved with AL-KO PURE over
more than 80 hours (the test duration time) at the high level concentration of 0.5
ppm (1187 μg/m3, about 7 times higher than the average living room level). This
corresponds to 0.2 μmol/s with a flow rate of 38.42 m3/h. The regeneration of a
saturated catalytic filter was also tested. When the catalytic filter of AL-KO PURE
is fully saturated with acetone, a 100% acetone destruction efficiency can be achieved
at 0.46 ppm concentration with 25% fan speed. Moreover the second pollutant, toluene,
has been also studied. 100% toluene abatement also is achieved with AL-KO PURE over
more than 80 hours (the test duration time) at the high level concentration of 0.2
ppm (811 μg/m3, 0.087 μmol/s with a flow rate of 38.42 m3/h). Finally, the availability
for the simultaneous removal of both pollutants, acetone and toluene, has been also
studied.
