Description

Medium-Temperature Tawny Or Grey Strips Iron Oxide Desulfurizer

Reaction principle

When the desulfurization reaction temperature is high, reaching 200-400°C, the desulfurization mechanism of iron oxide is different from that at room temperature, and it is generally considered to be carried out in the following three steps:

i. Reduction

Fe304 with desulfurization activity at 200~400 °C, and the active component in the desulfurizer is Fe20. Therefore, it should be fully reduced with reducing gas (H2 or C0) before use.

3Fe2O3+H2=2Fe304 +H2O. 3Fe2O3+CO=2Fe3O4+CO2

The reduction reaction is carried out at 170-300 °C, if the reduction temperature exceeds 300 °C, excessive reduction will occur, and iron oxide will be reduced to Fe304一FeO一Fe in turn, and when Fe0 or Fe appears, the activity of the desulfurizer decreases significantly. Due to the exothermic and counterheat of the reduction reaction head, a slight change in the concentration of the reduction medium may cause overtemperature and excessive reduction. Therefore, when carrying out the reduction operation, the reduction temperature and the concentration of the reduction medium should be strictly controlled.

ii. Organic sulfur conversion

The reduced Fe3O4 has a catalytic hydrogenation effect on some organic sulfur, and the reaction is as follows:

COS+H2=H2S+C0. CS2+2H2=2H2S+CH4

iii. Hydrogen sulfide removal

In the presence of hydrogen, the desulfurization reaction of Fe3O4 is:

Fe3O4+3H2S+H2=3FeS+4H20

Remark: Expect the sizes shown above, we can customize it as per your request.
Characteristics of Iron Oxide Desulfurizer:
1.Take high quality Iron oxide as main components
2. High Desulfurization Accuracy: 20 Times higher than normal Fe2O3.
3. Fast Speed Reaction: 5~6 Times faster than normal Fe2O3.
4. Working Penetrate Sulfur Capacity: 5~6 Times faster than normal Fe2O3.
5. High strength and water resistance: After boiling 2 hours or impreganated 30days, it doesn't pulverize and strength keeps the same.
6. Can be used in the absence of O2 or high CO2 conditions. In the absence of oxygen, H2S removal sulfur capacity is more than 15%.
It is widely is suitable for the fine removal of H2S in natural gas, (semi-)water gas, air gas, coke oven gas, shift gas, C02 regenerative gas, food C02, synthetic raw gas, biogas, waste gas and other famous gases, with a wide range of applications.
