Coal-based desulfurization activated carbon for biogas upgrading, natural gas treatment, and industrial gas sulfur removal. High sulfur capacity and long service life.
SRC-A is our coal-based activated carbon specifically formulated for sulfur compound removal from gas streams. The "SRC" designation identifies our Sulfur Removal Carbon series; "A" indicates the standard grade optimized for hydrogen sulfide (H₂S) and light mercaptan removal.
The coal base is selected for its high mesopore content, which accommodates the larger molecular dimensions of sulfur compounds while providing adequate surface area for high loading capacity. Steam activation develops the pore structure without introducing chemical residues that could interfere with sulfur adsorption chemistry.

Sulfur Removal Performance
SRC-A removes sulfur through a combination of:
Physical adsorption — trapping H₂S in the pore structure
Catalytic oxidation — converting H₂S to elemental sulfur on active surface sites
Chemisorption — binding sulfur species to surface functional groups
Q
What sulfur compounds does SRC-A remove from gas streams?
A
SRC-A is formulated for hydrogen sulfide (H2S) and light mercaptan removal. The coal base is selected for high mesopore content accommodating larger molecular dimensions of sulfur compounds while providing adequate surface area for high loading capacity. Steam activation develops pore structure without introducing chemical residues that could interfere with sulfur adsorption chemistry.
Q
What mechanisms does SRC-A use for sulfur removal?
A
SRC-A removes sulfur through three mechanisms: physical adsorption trapping H2S in pore structure, catalytic oxidation converting H2S to elemental sulfur on active surface sites, and chemisorption binding sulfur species to surface functional groups. This multi-mechanism approach provides high sulfur capacity and extended service life.
Q
What industries use SRC-A for biogas and natural gas treatment?
A
SRC-A serves biogas upgrading for H2S removal before grid injection or vehicle fuel use, natural gas processing for pipeline specification compliance, refinery gas treatment for sulfur recovery unit protection, landfill gas treatment for odor control and energy recovery, and pulp and paper digester gas and vent treatment.
Q
What particle sizes are available for SRC-A fixed-bed systems?
A
SRC-A is available in 4×8 Mesh (2.36–4.75mm) and 4×10 Mesh (2.0–4.75mm). These sizes are optimized for gas-phase fixed-bed applications where pressure drop and bed packing density are critical design parameters. The larger particle sizes minimize flow resistance in high-volume gas treatment systems.
