Product Overview
SRC-BL is our blended formulation desulfurization carbon, combining multiple coal-based carbon fractions with different pore structures to address the full spectrum of sulfur contaminants. The ""BL"" designation indicates the blended formulation; this approach recognizes that real-world gas streams rarely contain just one sulfur compound.
The blending strategy pairs high-micropore carbon (for H₂S and light mercaptans) with high-mesopore carbon (for heavy mercaptans, organic sulfides, and thiophenes). The result is a single product that handles complex gas compositions without requiring multiple carbon types in series.

Key Application Areas
- Natural gas with mixed sulfur species — pipeline and LNG specification compliance
- Biogas from mixed waste streams — food waste, agricultural waste, sewage sludge
- Refinery fuel gas — sulfur control for combustion emissions compliance
- Coke oven gas — H₂S, COS, and CS₂ removal
- Geothermal gas — H₂S removal for power generation
Blended Performance Advantages
- Single Product Simplifies Procurement: No need to manage multiple carbon inventories
- Optimized Bed Design: Uniform blend ensures consistent performance throughout the bed depth
- Cost-Effective: Blending achieves performance comparable to specialized carbons at lower cost
- Predictable Breakthrough: Balanced pore distribution provides gradual, predictable exhaustion
