Chemical Auxiliary Agent & desulfurizer

Introduction:

Iron Oxide Desulfurizer is made of iron,manganese salt and their oxide as raw material,pass through the process chemosynthesis to be active oxide, then add the assistant and binder to make it columnar solid .It has features of larger sulfur capacity ,small resistance,high purification capacity and good water resistance .For the city of pipeline gas, coke oven gas, methane, ordinary industrial raw material.Used for chemical fertilizerindustry transformation of oxygen gas desulfurization urea CO2 gas, synthetic ammonia N2 and H2 raw material gas, natural gas.

 Specifications:  Industrial Grade (0.001%=10ppm)

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°C without obvious change of sulfur content
6. In the condition of no O2 or large CO2 content conditions, the sulfur content won't alter

Desulfurizer and rebirth principle :

Fe2O3 . XH2O+3H2S==Fe2S3.XH2O+3H2O(desulfurizer formula)

Fe2O3 . XH2O+CS2==Fe2S3.XH2O+3H2O(desulfurizer formula)

Fe2O3 . XH2O+3/2O2==Fe2O3.XH2O+3S  (rebirth formula )
