PFH-E
purestar
The PFH-E advances beyond standard AE-type impregnation with enhanced alkaline loading and stabilization treatments that resist carbonization and maintain reactivity in high-acid, high-humidity environments typical of chemical processing and metal finishing operations.
Advanced Impregnation:
Base: Premium coconut shell carbon (iodine >1100 mg/g)
Primary impregnant: Sodium hydroxide (12-18% loading)
Secondary treatment: Potassium carbonate for H₂S optimization
Stabilization: Proprietary thermal process prevents impregnant migration
Quality assurance: SO2 protection time >35 minutes per GB 2890
Chemical Resistance:
Formulation resists hydrolysis and maintains >80% rated capacity in 90% RH conditions. Suitable for continuous operation in acid gas streams with intermittent liquid mist carryover.
