SRC-A Alkaline Impregnated Coal-Based Activated Carbon

Key Features

1. Alkaline Impregnation Treatment

SRC-A undergoes an additional alkaline impregnation process after base carbon activation. The impregnated components modify the carbon surface and support the removal of hydrogen sulfide and other targeted sulfur-containing compounds.

This treatment distinguishes SRC-A from conventional unimpregnated coal-based activated carbon.

2. Coal-Based Porous Structure

The product uses bituminous coal as its primary raw material. Its base carbon has a CTC adsorption value above 60% and a specific surface area above 900 m²/g, providing a porous structure for adsorption and supporting the impregnated treatment.

3. Extruded Cylindrical Pellet Form

SRC-A is manufactured as cylindrical extruded activated carbon pellets. The defined pellet geometry makes the product suitable for packed-bed adsorption equipment used in industrial gas purification.

4. Controlled Physical Specifications

SRC-A has specified moisture content, bulk density, mechanical strength and particle size distribution. These parameters provide buyers with measurable references for product evaluation, equipment compatibility and incoming quality inspection.

Applications

SRC-A is designed for industrial gas-phase treatment processes involving hydrogen sulfide and sulfur-related odors. It can be considered for the following applications:

1. Wastewater Treatment Odor Control

Wastewater treatment facilities can generate H₂S-containing exhaust gases during sewage collection, pumping, sludge handling and wastewater processing.

SRC-A can be evaluated for odor control systems treating gas streams from wastewater treatment plants, pumping stations, sludge tanks and related facilities.

2. Biogas and Landfill Gas Purification

Biogas and landfill gas may contain hydrogen sulfide generated during the decomposition of organic materials. H₂S needs to be controlled to help protect downstream equipment and meet gas quality requirements.

SRC-A can be considered as an activated carbon media for H₂S treatment in biogas purification and landfill gas treatment systems.

3. Oil and Gas Processing

Natural gas, associated gas and other hydrocarbon streams may contain hydrogen sulfide that requires removal before downstream processing or use.

Impregnated activated carbon can be used in suitable gas treatment and polishing systems. Product selection depends on inlet H₂S concentration, gas composition, pressure, humidity and required outlet conditions.

4. Food Processing Odor Control

Food processing, rendering and organic waste handling operations can generate sulfur-containing odors. SRC-A can be evaluated in gas-phase odor treatment systems handling these exhaust streams.

Its application in these systems should be based on the actual exhaust composition and operating conditions. This application does not imply direct food-contact use.

5. Chemical Manufacturing Gas Treatment

Chemical production and sulfur-handling processes may generate H₂S-containing exhaust gases and other sulfur-related emissions.

SRC-A can be considered for suitable industrial gas purification systems where impregnated activated carbon is used to control sulfur-containing contaminants.

Technical Advantages

Impregnated Surface for Sulfur-Containing Gas Treatment

Unlike conventional unimpregnated activated carbon, SRC-A incorporates an alkaline impregnation treatment intended to enhance its interaction with H₂S. The porous base carbon and impregnated components work together in the treatment of sulfur-containing gas streams.

Actual sulfur removal capacity and breakthrough performance depend on gas composition, humidity, temperature, flow rate and operating conditions.

Defined Base Carbon Activity

The base carbon used in SRC-A has a CTC adsorption value above 60% and a specific surface area above 900 m²/g. These values provide technical references for evaluating the underlying carbon material.

Mechanical Strength for Industrial Use

SRC-A has a specified hardness (strength) value above 90%. Mechanical strength is an important consideration for activated carbon used in packed-bed equipment, where pellet integrity during filling, handling and operation matters.

Multiple Particle Size Options

Available sizes include 4 mm, 3 mm and 2 mm pellets, as well as specified mesh sizes. Buyers can evaluate the suitable product form according to equipment design and process requirements.

FAQ

What Is SRC-A Impregnated Activated Carbon?

SRC-A is a coal-based extruded activated carbon that undergoes alkaline impregnation after steam activation. The impregnation treatment introduces active components onto the carbon surface, supporting the treatment of hydrogen sulfide and sulfur-containing gases.

It is mainly used in industrial gas purification and odor control applications.

What Raw Material Is Used in SRC-A?

SRC-A uses bituminous coal as its primary base material. The manufacturing process includes raw material processing, steam activation, extrusion and subsequent alkaline impregnation.

Can SRC-A Be Used in High-Humidity Gas Streams?

Gas humidity is an important factor when selecting impregnated activated carbon. Excessive moisture or condensation can affect adsorption performance and the effective use of the impregnation components.

For high-humidity applications, buyers should provide the expected operating temperature, relative humidity and gas composition so that the appropriate product and system conditions can be evaluated.

Can PURESTAR Provide Technical Documents and Samples?

Yes. TDS, MSDS and batch-specific COA are available for product evaluation. Sample availability and testing arrangements can be discussed with our sales team according to project requirements.

Is Thermal Regeneration Recommended for SRC-A?

SRC-A is an impregnated activated carbon, and its regeneration suitability depends on the impregnation chemistry and operating conditions. Thermal treatment may affect the active components.

Regeneration should not be assumed to restore the original performance. Any regeneration process should be evaluated and confirmed with the manufacturer before implementation.
