In the pursuit of cleaner energy sources like biogas, the effective removal of contaminants is a critical step. Hydrogen sulfide (H₂S), a common component in raw biogas and various industrial gas streams, poses significant challenges. It is not only highly toxic and corrosive to equipment like engines and pipelines but also a major environmental pollutant. NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of providing a robust solution to this problem with our advanced Iron Oxide Desulfurizer.

Our product is a specially formulated, high-performance catalyst designed for the efficient removal of hydrogen sulfide. Supplied as durable granular pellets, it offers a reliable and cost-effective method for gas purification. The core of our desulfurizer is high-purity iron(III) oxide (Fe₂O₃), enhanced with specialized promoters and supported on a robust carrier. This composition ensures optimal performance and a long operational lifespan.

The working principle is based on a proven chemical adsorption process. When the H₂S-laden gas passes through the catalyst bed, the iron oxide actively captures the sulfur compounds. The reaction is straightforward and highly effective:
Fe₂O₃ + 3H₂S → Fe₂S₃ + 3H₂O
This reaction converts the toxic hydrogen sulfide gas into solid, stable iron(III) sulfide, effectively sequestering it within the catalyst's porous structure.

Key Features and Advantages:
Our Iron Oxide Desulfurizer is engineered for superior performance, characterized by several key features:

• High Sulfur Capacity: With an impressive sulfur capacity of up to 700 mg/g, our catalyst can operate for extended periods before requiring regeneration, minimizing downtime and operational costs.
• Exceptional Efficiency: It achieves a desulfurization degree of 93-95%, ensuring that the treated gas consistently meets the stringent purity requirements for downstream applications, such as combined heat and power (CHP) units or injection into the natural gas grid.
• Regenerative Capability: A major economic advantage is its ability to be regenerated. Once saturated, the catalyst can be restored to its active iron oxide state through a controlled oxidation process (2Fe₂S₃ + 3O₂ → 2Fe₂O₃ + 6S), allowing for multiple cycles of use.
• Optimal Physical Properties: The catalyst's high mechanical strength and ideal bulk density (0.65-0.75 kg/L) prevent bed compaction and ensure low-pressure drop across the reactor, leading to energy savings.
