| Dioxins Decomposition Catalyst |
| Dioxins/Furans (DXNs) caused by incineration of municipal and industrial wastes have become a big
social problem. Methods of removal of DXNs in off -gases are adsorption by injecting activated carbon
powder, adsorption by activated carbon columns, decomposition by catalyst and etc., among which
catalytic method is the best as it can directly decompose DXNs to convert into harmless materials. |
 |
Reaction of DXNs Decomposition |
 |
| In the catalytic decomposition of DXNs, DXNs are reacted on the catalyst with oxygen in off-gases and are
converted into harmless carbon dioxide and water. In this reaction, hydrogen chloride is also formed at
the same time, level of which is as low as it does not affect to the environment at all, as the concentration
of DXNs in off-gases is very low. Furthermore, toxic organo-chlorine compounds such as Coplanar
PCBs other than DXNs can also be effectively decomposed by the similar reaction. |

1.Features |
| 1. |
Higher decomposing efficiency of more than 99%. |
| 2. |
Decomposition at a wide temperature range from 160ºC to 350ºC. |
| 3. |
No need for secondary treatment, as DXNs are decomposed into harmless carbon dioxide and water. |
| 4. |
Simultaneous removal of NOx in high efficiency by injecting ammonia. |
| 5. |
Less clogging of catalyst with dust and less pressure drop through catalyst layers. |
2.Catalyst Size |
|
| The honeycomb shape catalyst having outside dimension of 150mm×150mm and length of max.1,060mm
is used. |
