Granular activated carbon for acid gases

Raw material: Coconut shell

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

Presentation: 25 kg bags, 100 kg containers

Some applications:

  • Cartridge respirators (masks)
  • Drainage odors
  • Desulfurization of biogas and natural gas.
  • Air treatment in spaces where it is required to avoid corrosion caused by acid gases
  • Control in electronic component production areas

The Vapacid type activated carbon is manufactured from coconut shell and is impregnated with metal oxides that give it a high capacity for the elimination of acid gases and vapors present in air. These acids can be organic, such as acetic acid or mercaptans, or inorganic, such as sulfur dioxide and sulfuric, nitric, hydrochloric, and phosphoric acids.

In the case of hydrogen sulfide removal, Vapacid catalyzes the H2S - oxygen reaction:

2 H2S + O2 = S8 + 2 H2O

Unlike other impregnated carbons, Vapacid minimizes the formation of sulfuric acid by inhibiting the side reactions that produce it.

VAPACID adsorbs more than twice as many mercaptans as non-impregnated carbon, as it oxidizes them to disulfides

(2 RSH R2S2), which on the one hand are less odorous, and on the other, they are more easily adsorbable.

Among the main applications of this product are: odor control in drain vents (called

ports) and in wastewater treatment plants; corrosion control and component protection

electronics in harsh industrial environments; environmental control in museums or in manufacturing areas of

specialties, such as computer chips or pharmaceuticals; environmental control in processes

that use mineral acids.

Retains:

- All types of acid gases and vapors.

- All types of organic vapors (although with less capacity than a non-impregnated carbon).

Compound with which it is suggested to do organoleptic tests:

- Hydrogen sulfide (in the gas phase it is called hydrogen sulfide: H2S: It is the typical rotten egg smell. It is produced by reacting ferrous sulfide with sulfuric acid).

Like all inorganic acids, it is a toxic compound, so it must be handled with care and in low concentrations.
