Coconut shell activated charcoal

Micro 10 is a charcoal made from coconut shells, which is thermally activated in an atmosphere with highly reducing characteristics. Being of vegetable origin, it does not contain metals or other contaminants present in mineral coals.

By its nature, coconut shell activated carbon forms micropores on its surface, capable of adsorbing low molecular weight organic pollutants more efficiently. In addition, thanks to its high hardness, compared to coals of other raw materials, it is more resistant to erosion, which avoids material losses in the operation.

Control of specific gaseous contaminants in vents and enclosed spaces with mercury vapors.

Emissions of mercury vapors are a problem in processes that use this metal. Such processes include some foundries, the manufacture of certain types of electrical equipment, chlorine production plants using mercury cells, and many others.

In order to provide a practical and economical solution to this problem, Vapomer, a specially impregnated carbon for the retention of mercury vapor in gaseous streams, was designed.

Vapomer retains mercury vapors, even in streams with high humidity. The retention capacity of this product is about 0.3 kg of mercury per kg of carbon. The gaseous stream in the Vapomer bed should have a surface velocity between 6 and 12 m/min. The empty bed contact time is typically between 8 and 20 seconds, depending on the initial mercury concentration, the maximum allowable final concentration and the operating time of the carbon bed before it must be changed.

Vapomer is most efficient at high temperatures, as long as these are not higher than 100 °C. Once the practical adsorption capacity of this carbon has been exhausted.

Mercury is a trace element found in natural gas.

Mercury is harmful to the environment and to processes and transport equipment. Natural gas requires treatment to prevent the negative implications associated with the presence of this substance.

Our activated carbons’ high removal efficiency, low pressure drop and high hardness make it the superior technology for mercury removal.

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): 4×10, 6×12, 8×14, 14×30, 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.

Retains:

• Ammonia (NH3) and amines.
• All types of organic vapors (although with lower capacity than non-impregnated carbon).

Compound suggested for testing:

Ammonia (NOTE: organoleptic tests should not be performed, as ammonia fumes may cause respiratory arrest).

Granular activated carbon for acid gases and organic vapors

Granular carvacid raw material: Coconut shell.

Raw material carvacid in pellet: Mineral coal.

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

Presentation: 25 kg sacks, 100 kg bags.

Applications:

• Cartridge respirators (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.

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.

Granular activated carbon for acid gases

Granular vapacid raw material: Coconut shell. Raw material vapacid pellet: Mineral coal. Particle size range (mesh): 4×10, 8×14, 14×30, or 4 mm pellet.

Presentation: 25 kg sacks, 100 kg bags.

Some applications of activated carbon to remove acid gases:

• Cartridge respirators (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 granular 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.

Vapacid Pélet is manufactured by dispersing hydroxyl groups in the porous structure of the activated carbon. Thus, in the finished product, the carbon contributes its large surface area, and the hydroxyl groups participate in the chemisorption of acidic compounds. Vapacid Pélet adsorbs more than twice as many mercaptans as a non-impregnated carbon, as it oxidizes them to disulfides (2 R-SH → R 2 S 2 ), which on the one hand are less odorous, and on the other hand, are more easily adsorbed. The standard mineral activated carbon from which Vapacid Pélet is produced, is of very high capacity, and has a form of cylindrical pellets of 4 mm diameter, which cause very low pressure drop in gaseous streams.

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 activated carbon adsorbs more than twice as many mercaptans as unimpregnated carbon because it oxidizes them to disulfides (2 RSH R2S2), which are less odorous on the one hand and more easily adsorbed on the other.

Among the main applications of this product are: odor control in drain vents (called louvers) and in wastewater treatment plants; corrosion control and protection of electronic components in aggressive industrial environments; environmental control in museums or in specialty manufacturing areas, such as computer chips or pharmaceutical products; environmental control in processes using mineral acids.

Compounds retained:

– 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.

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.

NSF Certification of powdered activated carbon

Acid-washed coconut shell activated carbon, free of solubles.

• Acid-washed activated carbon.
• Raw material: Coconut shell.
• Particle size range (mesh): 8×30, 12×40, 20×50.
• Presentation: 25 kg bags, or 500 kg super bags.
• pH: 6.0 to 8.0

Coconut shell activated carbon tends to be microporous and adsorbs more efficiently the low molecular weight organic contaminants that are most present in well water. When washed with acid, ashes are removed, resulting in a purer activated carbon, as pores are freed and the effective surface area for adsorption of contaminants is increased.

All activated carbon of vegetable or mineral origin contains inorganic salts and elements, some of which are soluble in water. These come from the vegetable originating from coal. All vegetables contain minerals that remain in the product when the plant is carbonized.

Many people tend to confuse the term “solubles” with the term “ashes” erroneously, as they are concepts that are linked to each other, but should not be understood and used indiscriminately in this context. Ashes are all acid-soluble and acid-insoluble inorganic compounds or elements that are foreign to the material in question. Soluble is only the acid-soluble inorganic part, since every acid-soluble substance is soluble in water.

Acid-washed coconut shell activated carbon applications:

Purification processes can be affected by small amounts of soluble salts, modifying parameters such as pH, conductivity, and color of the fluid to be treated. The existence of soluble salts can increase the conductivity of the water, which is undesirable if the purification process is intended to obtain water with low conductivity levels, such as the generation of demineralized or ultrapure water. High conductivity may signal the existence of ionic impurities that need to be removed to meet water quality criteria. Acid-washed coconut shell activated carbon is commonly used to remove heavy hydrocarbons from recovered condensate.
