Comparison with Activated Charcoal
| Catalyst | Activated charcoal adsorption | |
|---|---|---|
| Reaction | Oxidation/reduction cycle | Adsorption (2 O3 + C → CO2 + 2 O2) Activated charcoal is gradually consumed and reduced into fines |
| Treatment efficiency | ≧99% | ≧99% |
| Allowable O3 concentration | Several tens of thousands of ppm | Several tens of ppm |
| GHSV | 10,000 h-1 | 3,000 h-1 |
| Running cost | Low | High |
| Replacement frequency/life expectancy |
1 year or more (due to catalyst poison) | Several month to 1 year |
| Replacement work | Easy | Difficult (due to dusting) |
| Amount of disposal waste | Low | High |
| Combustibility, explosion risk | None (inorganic matter) | Possible |
