Advantages of Iron Oxide Desulfurizer:

1. H₂S removal through dry method in room temperature, renewable material
2. Quick reaction: Space velocity: 1000~3000h-1, penetration space velocity: 6000h-1, twice to four-time of normal iron oxide
3. Large sulfur degree, high purification degree, reaching 25% in the condition of space velocity 1000h-1, normal pressure, water saturation, import H₂S 1%, export H₂S≤5×10-8 particle
4. High strength, good water tolerance, no pulverization under the condition of boiling by 2 hours or soaking by 30 days, and the strength remain the same as before, even in the condition of sudden pressurizing or relief with 12MPa, and undergoing blow test 100 times
5. Large applicable scope, 10~100℃ without obvious change of sulfur content
6. In the condition of no O₂ or large CO₂ content conditions, the sulfur content won't alter
 

Desulfuration and Renewal Principles of Xianke Iron Oxide Desulfurizer:
Desulfuration Reaction: Fe₂O₃.H2O+3H₂S=Fe₂S₃.H₂O+3H₂O
Renewal Reaction: 2Fe₂S₃.H₂O+3O₂=2Fe₂O₃.H₂O+6S (strong exothermic reaction)

Note: The desulfuration renewal can be cyclic regeneration when there is O₂ or O₂/H₂S≥2.5 in the air, and the reaction formula combines into 2H₂S+O₂=H₂O+2S with the iron oxide as the catalyst.
