Product Overview
SRC-BL 4mm is a blended impregnated coal-based columnar carbon formulated for gas streams containing a complex mixture of sulfur contaminants. While standard desulfurization carbons target hydrogen sulfide alone, SRC-BL addresses the broader spectrum encountered in real-world operations—light mercaptans, organic sulfides, and heavier thiophenic compounds alongside H₂S.
The blended base combines multiple carbon fractions with different pore structures, paired with impregnation chemistry tuned for multi-species sulfur capture. The 4 mm pellet form ensures uniform bed packing and low pressure drop in fixed-bed reactors, while the >90% crush strength survives handling and long-term bed stress.

Key Application Areas
- Wastewater & Sewer Gas Treatment — Captures mixed sulfur odors from municipal and industrial sewer systems where H₂S coexists with mercaptans and organic sulfides.
- Oil & Gas Desulfurization — Treats refinery fuel gas, natural gas, and associated gas containing varied sulfur species that single-mechanism carbons cannot adequately address.
- Laboratory Ventilation Systems — Removes sulfur-containing vapors from fume hood exhaust in chemical and pharmaceutical R&D facilities.
- Acid Gas & Chemical Processing Exhaust — Handles mixed sulfur and acid gas streams from chemical manufacturing, preventing corrosion and emission violations.
- Food & Waste Processing — Controls complex odors from mixed organic waste decomposition where sulfur compounds vary with feedstock and season.
Key Advantages
- Blended Formulation for Complex Streams: Multiple carbon fractions with tailored pore distributions ensure consistent removal across varying sulfur species, eliminating the need for layered or sequential carbon beds.
- Multi-Species Impregnation Chemistry: Surface treatment targets H₂S, mercaptans, and light sulfides simultaneously, outperforming single-purpose impregnated carbons in mixed-gas conditions.
- Robust 4 mm Mechanical Design: >90% hardness and uniform extrusion resist attrition during installation and operation, maintaining bed integrity and predictable flow dynamics.
- Cost-Effective Complexity Management: One product replaces multiple specialized carbons, simplifying procurement, inventory, and bed design for facilities with variable gas compositions.
