Application:
|
RCO * Regenerative catalytic oxidisers (RCO) * volatile organic compounds (VOC) * hazardous air pollutants (HAP) * carbon monoxide (CO) * nitrogen oxides (Nox) * organic particulate matter (OPM) |
| It is mainly used to remove the poisonous in dust burning stove, steel works, oil and chemical industry and so on, it needs to coat the catalyst | |
