What Is the Difference Between Coconut Shell Charcoal and Activated Carbon

Production Process
Coconut Shell Charcoal: Coconut shell charcoal is produced by burning coconut shells in a low oxygen environment, such as a kiln or a charcoal pit. The process removes volatile compounds and leaves behind carbonized coconut shell.Activated Carbon: Activated carbon is derived from coconut shell charcoal or other carbonaceous materials. It undergoes an additional activation process to create a highly porous structure. Activation methods include physical activation (e.g., steam activation) or chemical activation (e.g., using chemicals like phosphoric acid or zinc chloride).

Porosity and Surface Area
Coconut Shell Charcoal: Coconut shell charcoal has a moderate level of porosity and surface area, which is primarily determined by the carbonization process. It retains some internal pores but not as many as activated carbon.Activated Carbon: Activated carbon has a significantly higher level of porosity and surface area due to the activation process. It contains a vast network of small pores, including micropores, mesopores, and sometimes macropores. This high porosity results in a large surface area available for adsorption.

Adsorption Capacity
Coconut Shell Charcoal: Coconut shell charcoal has some adsorption capacity due to its natural porosity, but it is relatively lower compared to activated carbon. It can adsorb certain impurities, odors, or contaminants to some extent.Activated Carbon: Activated carbon has excellent adsorption capacity due to its highly porous structure. It can adsorb a wide range of substances, including gases, liquids, and dissolved contaminants. Activated carbon is commonly used for purification, filtration, and adsorption applications.

Why Coconut Shell Activated Carbon Is the Most Preferred Choice in the Industry

Activated carbon from coconut shell has predominantly pores in micro pore range. Almost 85-90% surface area of coconut shell activated carbon exists as micro-pores. These small pores match the size of contaminant molecules in drinking water and therefore are very effective in trapping them.
Peat and wood activated carbon has mostly meso and macro-pores which suit trapping of bigger molecules. The pore structure of coal carbons falls between coconut shell and wood based carbons.
Macro-pores are considered as an access point to micro-pores. Meso-pores do not usually play an important role in the adsorption unless the surface area of these pores is large, 400 m2/g or more.
The predominance of micro-pores in coconut shell carbon gives it tight structure and provides good mechanical strength and hardness and also high resistance to resist attrition or wearing away by friction.

How a Coconut Becomes Activated Carbon

Turn coconut into charcoal
Another term for activated carbon is activated carbon. Both terms refer to charcoal material that has been reheated and oxidized ("activated") to increase its porosity. Therefore, one of the necessary steps to turn coconut into activated charcoal is to turn coconut into charcoal. How do i do this?
There is heat. Lots and lots of heat.
But just throwing coconuts into the fire is not enough. Before heating the coconut, you must empty the coconut milk, scrape off the pulp, and make sure the shell is clean and dry. The fibers on the outside of the coconut also need to be removed.

Carbonization
Once the casing is clean and dry, there are several ways to turn this hard, woody material into charcoal. The process of turning coconut shells into charcoal is also called charring or pyrolysis. Essentially, coconut shells need to be subjected to very high temperatures (300 to 500 degrees Celsius) for several hours to break down into charcoal. The container in which this process occurs may vary.
One of the most popular methods of coconut charcoal production is in a drum kiln, a covered tank with a small chimney that creates a higher internal temperature by restricting the flow of oxygen. The bottom layer of coconut shells in the kiln is first carbonized, causing the coal at the bottom to glow orange. The stage from initial heating to orange light usually takes about 12 hours.

Reconciliation
Once this happens, the air flow to the bottom layer of the drum is cut off and the coal begins to cool – a stage called the "stabilization phase." This is important because if the charcoal burns for too long, it will turn to ash. The shells need to be caught at the right time during the carbonization process, not before or after.
What remains after the carbonization process is coconut charcoal, also known as coconut charcoal. The next step is to activate the coconut carbon so that it can act as a filter.

Steam activated
The main purpose of activation is to increase the pore size of the carbon so that it can capture more particles and contaminants. Coconut charcoal can be activated by soaking it with chemicals such as phosphoric acid, but there is also a steam activation method.
In the steam method, an inert gas is heated to about 800-1100 degrees Celsius in a rotary kiln, creating steam that dehydrates the charcoal and reduces its VOC content. This temperature is ideal - much higher, the charcoal begins to burn, leaving the manufacturer with less finished product. The temperature is much lower and the process takes too long.
As coconut charcoal steams, its pores expand until they are the perfect size to trap small molecules in the water. Once the pores are the correct size, you're left with activated coconut charcoal. Finally, the activated carbon is crushed, classified and sorted into different mesh sizes.

What Are the Uses of Coconut Activated Carbon

Activated Coconut Shell Charcoal Carbon Using Chemical-Physical Activation

The use of activated carbon from natural material such as coconut shell charcoal as metal absorbance of the wastewater is a new trend. The activation of coconut shell charcoal carbon by using chemical-physical activation has been investigated. Coconut shell was pyrolized in kiln at temperature about 75 - 150 °C for about 6 hours in producing charcoal. The charcoal as the sample was shieved into milimeter sized granule particle and chemically activated by immersing in various concentration of HCl, H3PO4, KOH and NaOH solutions. The samples then was physically activated using horizontal furnace at 400°C for 1 hours in argon gas environment with flow rate of 200 kg/m3. The surface morphology and carbon content of activated carbon were characterized by using SEM/EDS. The result shows that the pores of activated carbon are openned wider as the chemical activator concentration is increased due to an excessive chemical attack. However, the pores tend to be closed as further increasing in chemical activator concentration due to carbon collapsing.
