1) Temperature

The reaction temperature is different due to the different filler materials. The reaction temperature is given at home and abroad is generally in the range of 250-650℃, basically in the range of 315-400℃. The low-temperature reaction conditions are indeed not complete enough, and too high a temperature will cause problems. Lead to the existence of other side reactions.

2) Warm-up

Preheating is to make the temperature of the gas entering the converter be heated to the required reaction temperature in advance, and when it enters the reactive packing, it can be completely reacted.

3) Path

When the reaction progresses, the length of the path has a major impact on the efficiency and life of the reaction. Too long a path will affect the response time of the flow path.

4) Packing density

The density of the filler is an important factor in reaction efficiency. The greater the packing density, the higher the efficiency and the greater the air resistance.

5) Oxygen in the sample gas

The presence of oxygen will cause the oxidation of the filler itself, and gradually reduce the conversion efficiency.

6) Strong oxidizer in sample gas

The strong oxidant in the sample gas, such as ozone, accelerates the self-oxidation of the filler and gradually reduces the conversion efficiency.

7) Dust

Dust easily adheres to the surface of the filler, resulting in a smaller contact area, resulting in a decreased inefficiency.
