Prominent Systems, Inc. makes several different grades of impregnated activated carbon for those special applications where either standard non-treated carbon does not work or where activated carbon's adsorptive capacity can be greatly enhanced through impregnation.

• KOH Impregnated Coal Based Activated Carbon
• NaOH Impregnated Coal Based Activated Carbon
• KI/Potassium Iodide Impregnated Coal Based Activated Carbon
• CuO Impregnated Coal Based Activated Carbon
• Phosphoric Acid Impregnated Coal Based Activated Carbon
• Sulfur Impregnated Coal Based Activated Carbon
• Potassium Permanganate Impregnated Pelletized Coal Based Activated Carbon
• Silver Impregnated Coconut Shell Activated Carbon

 Sulfur Impregnated Coal Based Activated Carbon

Activated Carbon pellets impregnated with sulfur have been designed to remove mercury vapor steams. Sulfur impregnated carbon beds should not be exposed to liquid hydrocarbon as this can leach the sulfur impregnation from the bed. Organic Mercury can be effectively removed with sulfur impregnated carbons; however this is adsorption rather than chemical reaction, requiring significantly increased contact times.
