How to make activated carbon

Activated carbon is a type of carbon that has an increased adsorption surface area. It is also referred to as activated carbon, activated carbon or sometimes as activated carbon. In order to produce activated carbon, the carbon source is treated under certain conditions to increase its surface area and/or the number of pores.

In order to produce activated carbon, the carbon source is treated under certain conditions to increase its surface area and/or the number of pores. On average, the estimated surface area of one gram of activated carbon is about 500 square meters.

 

The adsorption properties of activated carbon have a variety of uses. When a compound is brought close to this charcoal, the latter adsorbs the substance by chemical attraction. It is considered to be the most effective antidote to date. When administered early, activated charcoal can adsorb approximately 60% to 70% of ingested poisons. Due to its many advantages and multiple applications, it is produced on a large scale. Commercially, it is available in dry powder, liquid and tablet forms.

 

water treatment chemical can be manufactured at home through a chemical activation process. Production requires coconut shells, calcium chloride or zinc chloride solutions, combustion baths, ovens and mixers.

 

 

Raw materials that can be used

Activated charcoal can be made from a variety of carbon-rich materials such as wood, coal, bone, coconut shells, nut shells, peat and agricultural residues. The pore properties and adsorption capacity of activated carbon depend on the type of raw material used for its production. It also depends on the method used for its activation. Black bone charcoal is the one with the lowest adsorption capacity, while gray-brown bone charcoal is the best. White carbon exhibits a low capacity for fluoride removal. The surface area of these bone carbons is usually lower than that of activated carbon. However, they have high adsorption of certain metals such as copper, zinc and cadmium.

Activated carbon produced from nut shells and coconut shells has the best adsorption capacity and the largest surface area. Even if you use hardwood, the procedure is the same, but using coconut shells produces a high quality activated carbon.

â–´ Burn sinks, drums or slender iron containers to burn the shells.

â–´ Ovens

â–´ A 25% concentrated solution of calcium chloride (CaCl 2 ) or zinc chloride (ZnCl 2 ) is available at brewing supply stores or pharmacies. To make this solution, dissolve 250 g of CaCl 2 in 1000 ml of water and increase the proportions in the same ratio as you require.

Production process

Before starting the process, you can peel the coconut shells, wash them thoroughly with water and allow them to dry completely. If they are not dried properly, they will be difficult to burn.

✱ Want the coconut shells to be free of moisture, add them to the burning sink (or drum). Measure the temperature and make sure it is adjusted to approximately 600 - 900 degrees Fahrenheit. Maintain the recommended temperature range and keep burning for about 4.5 hours or until the coconut shells turn to ashes. For safe handling, you can leave the ashes until they cool down.

Once the ashes have cooled, carefully remove from the sink and transfer to a clean plastic bucket. Then, pour a 25% solution of calcium chloride or zinc chloride concentrate into the plastic bucket.

✱ The amount of calcium chloride or zinc chloride solution should be such that the ash is completely immersed in the solution. Cover the pail with a lid and leave it for 20-24 hours. During this process, the chemical leaches into the ash and converts the ash into activated carbon. This is called chemical activation and makes it highly porous and adsorptive. The next step is to remove the charcoal from the chemical solution and transfer it to a drain pan. The treated charcoal is allowed to drain for about 1 hour.

✱ To remove the trace chemicals from the charcoal, you can wash and rinse it repeatedly with sterile water. Thorough washing is essential to remove the chemical solution, otherwise it will remain in the charcoal. This is one of the most common problems in manufacturing activated charcoal through chemical activation procedures. After washing, the charcoal is placed in a tray for draining. After this, transfer the charcoal to the oven, set the temperature to approximately 215 - 230 degrees F and bake for approximately 3 hours.

After baking for the specified time, remove the charcoal from the oven and crush it with the help of a blender. You can also use a hammer to grind the charcoal into a powder form. For future use, store the powdered charcoal in a zip-lock bag or sealed container.

Although activated charcoal can be made at home if you have the materials and equipment needed, it is also readily available at many drugstores.
