| De-NOx Catalyst |
Nitrogen oxides (NOx) discharged from various stationary combustion systems (such as industrial
boilers, private power generation systems and furnaces, power stations) and metal etching are believed
to be the major air polluting substance causing air pollution, and regulations for controling NOx emission have
been effectuated in many countries. For NOx reduction, the selective catalytic reduction (SCR), using
ammonia as a reducing agent has been widely used. The De-NOx catalysts used for this process are
key of SCR.
Nippon Shokubai's De-NOx catalysts are widely used in the De-NOx systems for various exhaust gas
sources such as boilers and power stations.

1. Features |
| 1. |
Suitable catalyst selection complying to various exhaust gas sources such as boilers, gas turbines,
diesel engines, cement kilns, sintering and heating furnaces, waste incinerators. |
| 2. |
High NOx-reducing rates in a wide temperature range from 160ºC to 600ºC. |
| 3. |
Durable catalysts by SOx in the exhaust gas and various poisonous substances in the dust keep a
high De-NOx activity for a long period of time. |
| 4. |
Due to low SO2 oxidation rate, less formation of ammonium sulfates. |
| 5. |
By changing the number of cells (sieve opening) of catalyst , it is applicable to any exhaust gas from coal - fired boilers with a high dust abrasion resistivity. |
| 6. |
High heat-resistance and water-resistivity. |
