PFH-K
purestar
While most impregnated carbon targets acid gases, PFH-K addresses the opposite challenge: alkaline gas neutralization. Phosphoric acid impregnation creates reactive sites that convert gaseous ammonia to stable ammonium phosphate within the carbon pore structure.
Acid Impregnation Chemistry:
Base: High-strength coal columnar carbon (4.0mm)
Impregnant: Phosphoric acid solution (8-12% P2O5 loading)
Neutralization: NH3 + H3PO4 → NH4H2PO4
Capacity: >25g NH3/100g carbon at breakthrough
Selectivity: Effective for NH3, amines, pyridine, and basic organics
Engineering Considerations:
Acid-impregnated carbon requires humidity (RH >40%) for optimal reaction kinetics. Dry ammonia streams show reduced initial efficiency until moisture equilibrium establishes.
