Description
Activated carbon for organic gases
Carvapur granular carbon is a highly microporous activated carbon, which has the property of preferentially adsorbing organic molecules with a molecular weight between 55 and 250. Such molecules tend to be volatile, so they are typically present in air and other gases.
It is manufactured from coconut shell and is thermally activated to obtain an enormous surface area, which gives it a high adsorption capacity. Typically, it retains between 0.2 and 0.8 kg of contaminants per kg of coal. Carvapur has a high hardness and therefore breakage losses during handling are low.
It is recommended that the surface velocity of the air or gas being purified with this carbon be between 10 and 30 m/min, and that the contact time in an empty bed be greater than 0.1 seconds.
Activated carbon to retain organic compounds in air and gases
- Raw material: Coconut shell
- Particle size range (mesh): 4×10, 8×14, 14×30, or 4 mm pellet.
- Packaging: 25 kg sacks, 100 kg bags, 100 kg bags
Applications:
- Cartridge respirators (face masks)
- Paint booths
- Stove hoods
- Solvent recovery
- Compressed air purification (diving tanks and hospitals)
- Industrial contaminant control (such as carbon dioxide, hydrogen, helium, acetylene and carbon monoxide)
- Air conditioning
- Air recirculation.
Compounds retained by activated carbon:
Of the contaminants listed, some are specific chemical compounds. Others represent a class of compounds and others are mixtures of varying composition. The capacity of activated carbon for odors varies with the concentration of odors, as well as with the humidity and temperature of the air.
A = High capacity (coal retains 20% to 50% of its own weight).
B = Satisfactory capacity (retains 10% to 25% of its weight).
C = Sufficient capacity to give good service under particular operating conditions, we recommend testing.
D = Low capacity. Activated carbon does not give adequate service under ordinary operating conditions.
*= A carbon impregnated with a certain substance significantly increases the adsorption capacity of this compound.
