Diesel Engine Exhaust Gas Purification SCR

 

The Mechanism of Action of SCR DeNOx Catalyst

Injection of urea solution: The urea solution is injected into the exhaust gas stream. The heat from the exhaust gas converts the urea into ammonia (NH₃) and carbon dioxide (CO₂).


Mixing and reaction: The exhaust gas, now containing ammonia, passes through a catalyst. This catalyst is usually made of materials such as titanium oxide (TiO₂), vanadium (V₂O₅), or other suitable catalytic materials.


Reuction reaction: In the presence of the catalyst, the ammonia reacts with the nitrogen oxides (NOx) in the exhaust gas. This chemical reaction converts the NOx into nitrogen (N₂) and water (H₂O), both of which are harmless. The overall reaction can be simplified as follows:


4NO + 4NH₃ + O₂ → 4N₂ + 6H₂O
6NO₂ + 8NH₃ → 7N₂ + 12H₂O


Emission of clean gas: The resulting mixture, now containing harmless nitrogen and water vapor, is emitted from the exhaust system.

 

Key Pollutants Removed by SCR DeNOx Catalyst

Particulate Matter (PM)

These tiny particles can penetrate deep into the lungs and are a serious health risk. SCR DeNOx Catalysts help to trap and burn off these particles.

 

Hydrocarbons (HCs)

Unburned fuels that form toxic compounds. An SCR DeNOx Catalyst, in conjunction with other treatments like Diesel Particulate Filters (DPFs), can reduce the release of HCs.

 

Nitrogen Oxides (NOx)

NO and NO2 emissions contribute to the formation of smog and acid rain. The core function of SCR DeNOx Catalyst is to reduce these NOx emissions.

 

 

 

SCR DeNOx Catalyst Applications

Boilers: Harmful pollutants can be increasingly harmful in environments in which quite a large of energy is being produced. As a result, many boiler systems employ it. It's applied in many different places, like power plants, factories, office buildings, and hotels.


Diesel engines: SCR DeNOx Catalyst didn't have its major breakout into diesel engines until relatively recently when environmental policies became somewhat stricter around the world. SCR DeNOx Catalyst has found many applications in diesel vehicles, ranging from large ships to personal automobiles.

FAQ

 

Q: How does an SCR DeNOx catalyst work?

A: The catalyst promotes a reaction between NOx and a reducing agent, usually ammonia generated from urea solution. Under suitable temperatures, NOx is converted into nitrogen and water. The catalyst itself is not consumed during the process and continues to support the reaction over long operating periods.

Q: What are the main applications of SCR DeNOx Catalysts?

A: SCR catalysts are widely used in power plants, steel plants, cement factories, chemical plants, waste incineration systems, and diesel vehicles. They are especially important in industries that must meet strict environmental emission standards.

Q: What materials are commonly used in SCR catalysts?

A: Common catalyst materials include vanadium, titanium, tungsten, molybdenum, and zeolite-based formulations. Different materials are selected depending on operating temperature, sulfur content, and exhaust gas composition.
