Activated Carbon Flue Gas Grade
Activated Carbon Flue Gas Grade is a highly porous material produced from carbonaceous source materials (like coal, coconut shells, or wood) that has been treated to significantly increase its internal surface area. Flue Gas Grade Activated Carbon is specifically formulated and sized for use in industrial pollution control systems to adsorb pollutants directly from the hot, corrosive exhaust gases (flue gas) generated by power plants and industrial furnaces.
Main Composition and Activation
The source material and activation method determine the final pore structure and surface area.
| SOURCE MATERIAL | ACTIVATION METHOD | PRIMARY USE FOCUS |
| Coal/Lignite Base | Thermal or Chemical | Large pore structure suitable for gas-phase contaminants. |
| Impregnated Carbon | Treated with chemicals (e.g., sulfur or halogens) | Enhanced specificity for Mercury (Hg) removal. |
| CLASSIFICATION | SURFACE AREA | PRIMARY ADSORPTION TARGETS |
| Flue Gas Grade | Very High (500-1500 m2/g) | Mercury (Hg), Dioxins/Furans, SO2, NOx. |
Key Performance Metrics
| PROPERTY | TYPICAL PERFORMANCE | MECHANISM OF ADVANTAGE |
| Adsorption Capacity | HIGH | Large internal surface area and pore volume provide numerous sites for contaminant molecules to stick. |
| Particle Size | Typically Fine Powder or Granular | Powdered Activated Carbon (PAC) is used for injection into the flue gas stream for rapid, single-pass adsorption. |
| Reactivity | HIGH | Impregnation enhances the chemical affinity for hard-to-capture species like elemental mercury. |
Activated Carbon Flue Gas Grade
Advantages and Key Characteristics
Flue Gas Grade Activated Carbon is a primary technology for meeting strict air quality standards, particularly concerning toxic trace elements like mercury.
- Mercury Abatement: This is the most critical application. Activated carbon, especially in its impregnated form, is injected into the flue gas. The carbon chemically reacts with and captures elemental mercury vapor (Hg0) and oxidized mercury (Hg2+), which are then removed by the downstream baghouse or electrostatic precipitator (ESP).
- Dioxin and Furan Removal: The large organic molecules of dioxins and furans are effectively adsorbed by the carbon’s pore structure, which is crucial for emissions control in waste incinerators.
- Versatility in Pollutant Control: Depending on the base material and treatment, activated carbon can be tailored to remove other gaseous pollutants, including volatile organic compounds (VOC) and some nitrogen oxides (NOx).
- Process Flexibility: PAC injection systems allow plant operators to adjust the carbon injection rate dynamically based on the measured pollutant levels, providing a flexible and immediate means of compliance.
Typical Industries and Applications
This specialized carbon is essential for large-scale combustion operations:
- Coal-Fired Power Plants: Mercury (Hg) control to meet environmental regulations (e.g., MATS standards).
- Waste Incineration Facilities: Removal of dioxins, furans, and heavy metals before gas discharge.
- Cement Kilns and Industrial Furnaces: Control of trace elements and organic pollutants from high-temperature exhaust streams.
Selection and Usage
Selection hinges on the specific pollutant and the flue gas temperature:
- Impregnated vs. Non-Impregnated: Impregnated carbon is required if the primary target is elemental mercury (Hg0), as it facilitates the oxidation necessary for capture. Non-impregnated (standard) carbon is often sufficient for organic pollutants like dioxins.
- Injection System: In most flue gas applications, Powdered Activated Carbon (PAC) is pneumatically injected into the ductwork, mixed with the flue gas, and collected downstream.
Technical Guidance: The efficiency of the carbon is highly dependent on the flue gas temperature and the presence of other gases. Optimal Hg capture often occurs in a specific temperature window, and high levels of sulfur or moisture can sometimes interfere with adsorption. The spent carbon, now loaded with pollutants, must be properly handled and disposed of, often with the captured fly ash.

❓ Frequently Asked Questions (FAQ)
Question | Elaborated Answer |
Q: What is the Refractoriness Under Load (RUL) of your refractories? | A: Refractoriness Under Load (RUL) is a critical property that defines the maximum temperature our materials can withstand while under compressive stress before deforming (softening). Since we offer a wide range of materials—from Alumina-Silicate Bricks to high-performance Silicon Carbide Bricks—the RUL varies significantly. For specific product data, please refer to the product data sheet or submit a quote request for the material you are interested in. |
