Product images are demonstrative and may vary from the physical product.

Granular activated carbon for acid gases

Raw material: Coconut shell

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

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

Some applications:

  • Cartridge respirators (face masks)
  • Drainage odors
  • Desulfurization of biogas and natural gas.
  • Air treatment in spaces where corrosion caused by acid gases must be avoided.
  • Control in electronic components production areas

Vapacid type activated carbon is manufactured from coconut shell and impregnated with metal oxides that give it a high capacity for the removal of gases and acid 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 sulfuric acid formation by inhibiting sulfuric acid-producing side reactions.

VAPACID adsorbs more than twice as many mercaptans as unimpregnated carbon because it oxidizes them to disulfides.

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

Among the main applications of this product are: odor control in drainage vents (so-called

and in sewage treatment plants; corrosion control and component protection

in aggressive industrial environments; environmental control in museums or in manufacturing areas of

such as computer chips or pharmaceuticals; environmental control in processes

that use mineral acids.

Retains:

– All types of vapors and acid gases.

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

Compound with which organoleptic tests are suggested:

– Hydrogen sulfide (in 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.
