Activated Carbon for Ammonia Gases and Amines

Description

Granular activated carbon for adsorption of ammonia gases and low molecular weight amines.

Raw material of granular activated carbon to retain ammonia: Coconut shell. Raw material of pellet activated carbon to retain ammonia: Charcoal. Particle size range (mesh): 4x10, 6x12, 8x14, 14x30, or 4 mm pellet. Presentation: 10 kg pail, 25 kg bags, 100 kg bags.

Applications of activated carbon for ammonia:

Cartridge respirators (masks).
Control of pollutant emissions in various chemical processes.
Odor control in photocopy rooms.
Fish processing.

After activation, the carbon is impregnated with acidic surface groups, which are very stable and strongly bound to the carbon surface. These groups give the carbon a great capacity for the retention of alkaline molecules, such as ammonia and low molecular weight amines.

Vapamon must be handled with the care corresponding to an acidic material and must be kept in an environment as dry as possible, since it is hygroscopic (it adsorbs moisture). However, these precautions are compensated by the capacity of this coal, which is approximately double that of other impregnated coals manufactured to retain gases and alkaline vapors.

Vapamon pélet, an activated carbon impregnated with non-volatile acids, retains this family of compounds by chemical reaction on the carbon surface. The adsorption capacity of Vapamon pélet is more than double that of a non-impregnated carbon. Among its main applications are: odor control in wastewater treatment plant vents or in meat product production and storage areas; and odor control in the multiple processes that use ammonia. The standard mineral activated carbon from which Vapamon pellet is produced is of very high capacity, and has a cylindrical pellet shape of 4 mm in diameter, which causes very low pressure drop in gaseous streams.
