What is Activated Carbon?
There are many types of charcoal on the market such as coal, anthracite, peat, charcoal ....
When it comes to charcoal is often said to activated carbon made from coconut shells PROPERTIES FOR DISSEMINATION AND USE ITS. Thus, the activated carbon when it is implied coconut shell charcoal.
Activated charcoal is created like?
In Vietnam, there are many coconut-growing regions such as Ben Tre (South West), Binh Dinh (Central)
(See Ben Tre coconut, then remember where or Company carrying water for irrigation Coconut Tam Quan)
Coconut products can be used in the form of fresh fruit to get water or in dry copra coconut oil processing
Coconut after coconut roducts removed inside the coconut shell waste (coconut shells) is omitted. Recent coconut shells are used as handicraft products ... and the export value, creating jobs locally.
However, handicraft products only solve part of the larger amount of coconut shells. One part is used to replace wood burning in a household or burned in incinerators produce high heat, flammable.
Most of the rest is used to make coconut shell charcoal, coconut shell charcoal because it is good coal, not less heavy metals, toxic substances such as coal, charcoal slurry.
The process of producing coconut shell charcoal as follows:
ingredients
The choice of material is the first important step to ensure a good quality product.
Choose old coconut shell coal to the structure, not the soot crumbled at a later stage.
Coconut shell after you do, will be added to the furnace in the absence of oxygen at high temperature of about 1200oC. Due to a lack of oxygen to the combustion process takes place is not completely formed charcoal.
Coal at this stage is the active form of money, in the form of shavings, used for water purification, wastewater purification.
For activated carbon with a porous structure and is much lighter, charcoal undergoes activation by steam at a temperature of 800 - 900oC.
During the activation process, charcoal is burned to produce holes with very small size of charcoal. Depending on the time will be activated coals with different properties
- If activation of slow, low level charcoal burned this little hole (hole diameter from 0.1 - 15 angstron A0): This charcoal gas adsorption well, used to absorb toxic gases, solvent vapors, chemicals.
- If activation of fast, high-temperature coal central hole (hole diameter from 15 - several hundred A0) and is capable of bleach, color absorption in solution. | Activated carbon removes color type solution is used translation, liquid products
The holes created indefinitely, creating crisscrossed charcoal porous structure. With 1 volume of charcoal along the same, but after activation, the specific surface area of activated carbon had increased a thousand times.
Because of the structure of activated carbon is very porous so it is capable of absorbing odors, toxic gases in the air are very high. Keep residue, heavy metal ions in water well.
Therefore, activated carbon is widely used in manufacturing, civil.
In addition to tablets, granular activated carbon was ground fine to elaborate on va1v other materials to create carbon fabric klha63u page, Silk makes carbon gas masks, porous carbon air filter frame ....
