Product Description

Product Description

iron oxide desulfurizing granules can remove hydrogen sulfide (H2S) from fuel gas to meet environmental requirements.

We offer three desulfurizing granule series: MT-1, MT-2, and MT-3. Below are the specifications for each series, all of which can be customized to suit your specific working conditions:
 

Product Name	Active Ingredient	Size (mm)	Strength (N/cm)	Bulk Density (kg/L)	Breakthrough Sulfur Capacity
MT-1 series: iron oxide desulfurizing granules	Fe2O3	diameter: 3-8 length: 3-20	≥60	0.7-0.85	12%-18%
MT-2 series: modified iron oxide desulfurizing granules	Fe2O3 + FeOOH	diameter: 3-8 length: 3-20	≥55	0.75-0.9	20%-25%
MT-3 series: iron oxyhydroxide desulfurizing granules	FeOOH	diameter: 3-5 length: 3-15	≥50	0.8-0.95	30%-38%

Desulfurization Principle:
Fe2O3·H2O + 3H2S = Fe2S3·H2O + 3H2O
2FeOOH + 3H2S = Fe2S3·H2O + 3H2O

Our factory

Certifications

Our certifications: ISO9001 for quality management, ISO14001 for environmental management, and ISO45001 for occupational health and safety management.

Quality Assurance

Our desulfurizing granules' quality is guaranteed, because:
1.Before production, the inspections of raw materials ensure that all raw materials used for desulfurizing granules are qualified.
2.During production, our synthetic technology is mature. There is a central quality control lab testing quality of semi-finished products at each reaction step. The production process adopts automated control, with operation records available online to ensure sufficient reaction time. 
3.After production, each batch undergoes sample testing. Only batches that pass this testing are stored in the warehouse, ensuring that all products leaving the factory are qualified.

Besides, there are a testing lab and a R&D center in our factory, offering both excellent quality assurance & technological innovation:
