Granular activated carbon for acid gases and organic vapors

Raw material: Coconut shell

Particle size range (mesh): 4×10, 8×14, 14×30 or Pellet 4 mm

Packing : 25 kg bags, 100 kg bags, 100 kg quads

Applications:

  • Cartridge respirators (face masks)

  • Air treatment in spaces where corrosion caused by acid gases must be avoided.
  • Control in electronic components production areas

Carvacid is an activated carbon with adsorption capacity for both organic vapors and acid gases. It is manufactured by partial impregnation in an alkaline medium of a coconut shell carbon with a highly developed porosity. The carbon provides part of its surface to adsorb organics and another part as a catalyst for the oxidation of acid contaminants.

Carvacid removes more than twice as many mercaptans as a non-impregnated carbon because it oxidizes them to disulfides (RSH R2S2), which are more easily adsorbed, making them less odorous.

Compounds retained:

  • All types of vapors and acid gases
  • All types of organic vapors and gases whose molecular weight is greater than 60.
