Xyf-1 Granular Iron Oxide Desulfurizer

To remove the H2S in pipeline gas of city, water gas, semi-water gas, coke oven gas and , Zhongyuan Institute of Chemical purification and us together research and developed the XYF-1 granular iron oxide desulfurizer, which has the features as following:
1a High desulfurization precision: when the H2S content reach to 2000mg/Nm3 in inlet, it will be decreased into below 5mg/Nm3.
2a Large sulfur capacity: 6%-8% for one time.
3a High water resistance strength: not change to mud under the condition of boiling for 2 hours or soaking for 15 days; after drying, the activation and strength not change.
The desulfurizer is suitable for the removal of H2S from water gas, semi-water gas, coke oven gas, and city pipeline gas.
a a Desulfurization and regeneration theory:
Fe2O3a cXH2O+3H2S== Fe2S3a cXH2O+3H2O(desulfurization chemical formula)
Fe2S3a cXH2O+3/2O2== Fe2O3a cXH2O+3S(regeneration chemical formula)
The H2S reacts with the activated iron oxide in desulfurizer and produce sulphide. Then the sulphide reacts with oxygen in feed gas and produce elemental sulfur which will deposit in the micro-pore of desulfurizer thus making the desulfurizer regenerate and reaching to the goal of desulfurization.
