ARC-A Impregnated Coal Columnar Activated Carbon for Ammonia Removal

ARC-A is a specialized 4mm coal columnar activated carbon chemically impregnated for selective ammonia and amine removal. The columnar form provides high mechanical strength and low pressure drop in fixed-bed gas treatment systems.

Product Overview

ARC-A columnar activated carbon is produced from high-quality bituminous coal, crushed, extruded with binder, and activated by high-temperature steam. Post-activation impregnation with phosphoric acid creates active sites for chemisorption of alkaline gases.

Designed for ammonia removal in agricultural facilities, wastewater treatment plants, fertilizer production, and chemical processing operations where ammonia odors or toxic exposures are concerns.

Technical Advantages

Targeted Contaminant Removal & Enhanced Chemical Reactivity

Our specialty impregnated activated carbons combine premium coconut shell or coal substrates with precisely loaded active agents (silver, copper, zinc, or proprietary catalysts) for selective pollutant capture.

Silver-impregnated variants (PSD-Ag+) deliver >99% bacteria inactivation for drinking water safety, while sulfur-impregnated grades (SRC-A/SRC-E) achieve >98% mercury and heavy metal removal.

The ABEK-type comprehensive protection carbon provides multi-gas defense against organic vapors, acid gases, ammonia, and formaldehyde for industrial respirators and nuclear facility protection. Custom impregnation available for specific contaminant challenges including H₂S, SO₂, NOx, and radioactive iodine removal.

FAQ

Q1: How does ARC-A remove ammonia?

A: ARC-A uses phosphoric acid impregnation to create acidic sites that chemically react with alkaline ammonia gas, forming stable ammonium compounds through chemisorption.

Q2: What is the typical service life?

A: Service life depends on ammonia concentration and airflow. At typical agricultural facility levels (5-20 ppm), service life ranges from 6-18 months.

Q3: Can ARC-A be regenerated?

A: Thermal regeneration can partially restore ammonia capacity, but chemisorbed ammonia compounds are more difficult to remove than physically adsorbed contaminants. Replacement is typically more economical.

Q4: Is ARC-A effective against other amines?

A: Yes, ARC-A effectively removes methylamine, dimethylamine, and other low molecular weight amines common in chemical and agricultural environments.

Q5: What humidity levels affect performance?

A: High humidity (>80% RH) can reduce ammonia capacity by competing for adsorption sites. Pre-drying or selecting higher capacity may be needed in humid environments.
