Virgin Powdered Activated Carbon

Virgin Powdered Activated Carbon


Our virgin activated carbon is manufactured to meet or exceed the typical requirements for a carbon based injectate (CBI).  Due to the highly variable mixture of solvents and fuels that our found at impacted properties, GR-320-IRC-V is a proprietary mixture of coconut shell and bituminous coal virgin carbon. We use a mixture of virgin carbons because some contaminants have a higher affinity for coconut shell carbon, where others bond more readily to bituminous coal.  Our GR-320-IRC-V is a premium carbon that is characterized by the following properties:

  • Very high surface area
  • High hardness
  • Low dust generation
  • Excellent purity
  • Low ash content
  • Highly developed pore structure
  • NSF 61 Certified
  • Excellent dispersion properties
  • High organic removal efficiency
  • Iodine number up to 1250
  • Very fine grained with 90% passing the 325 mesh (smaller than 44 microns)

All virgin carbons are definitely not created equally. Some lower priced and very high priced carbon products can have low iodine numbers, high dust content, high priced additives with questionable value, and in liquid form may be up to 75% water.
