Materials Of Nut Shell Activated Carbon

The raw materials of activated carbon mainly come from various fruit shells, such as coconut shells, apricot shells, walnut shells and so on. These fruit shells are rich in cellulose and hemicellulose, and can form porous structure after carbonization, which is suitable for the raw material of activated carbon. In addition, the silicon element in the fruit shell can also improve the adsorption performance of activated carbon. When selecting raw materials, attention should be paid to the purity, moisture content and particle size distribution of raw materials to ensure the quality of products. The raw material source of activated carbon in fruit shell is very wide, and the price is relatively low.

Process of Nut Shell Activated Carbon

Preparation of materials
In the preliminary preparation work, a large number of nutshell should be collected. These nutshell need to be washed, dried and then broken into pieces. This step is mainly to remove impurities and residues to ensure the smooth progress of the next stage.

Carbonization
The carbonization stage is one of the major steps in the production of nutshell activated carbon. At this stage, the nutshell undergoes high-temperature carbonization, and the organic matter in it gradually decomposes into carbon element.

Activation
The activation stage is another key step in the production of activated carbon. At this stage, the carbonized fruit shell is further activated to improve its adsorption properties. Steam activation is the reaction of carbonized fruit shells with water vapor at high temperatures to form more microporous structures on the surface. Carbon dioxide activation involves treating carbonized fruit shells at high temperatures in a carbon dioxide atmosphere to make the surface rougher, thus enhancing the adsorption capacity.

Washing
After activation, some ash and impurities will remain on the surface of nutshell activated carbon, which needs to be rinsed. The rinsing process generally uses acid-base solution or pure water to remove impurities and ash on the surface of activated carbon.

Drying
The rinsed nut shell activated carbon needs to be dried to remove the moisture inside and improve its adsorption performance. The drying process is generally carried out using high-temperature hot air drying equipment to accelerate water evaporation and remove internal moisture.

How to Maintain Nut Shell Activated Carbon

Please store Nut Shell Activated Carbon in a cool, dry, and well-ventilated area, away from moisture and direct sunlight.

When handling the product, wear appropriate protective gear, such as gloves and a mask, to avoid skin or respiratory irritation.

Before using our activated carbon in any application, consult the relevant technical specifications and guidelines to ensure the product's suitability and optimal performance.

Nut Shell Activated Carbon may generate dust during transportation and handling. Take necessary precautions to minimize dust exposure and maintain a safe working environment.

Factors to Consider When Choosing Nut Shell Activated Carbon

When selecting nut shell activated carbon for a specific application, several factors should be taken into account:

Particle size

The particle size of nut shell activated carbon affects its adsorption efficiency. Finer particles provide a larger surface area for adsorption, leading to better purification performance. However, the particle size should be selected based on the specific requirements of the application to balance adsorption capacity and pressure drop.

Surface area

The surface area of nut shell activated carbon determines its adsorption capacity. Higher surface area enables greater adsorption of contaminants. Manufacturers often specify the surface area of their activated carbon products, allowing users to select the appropriate grade based on their needs.

Adsorption capacity

The adsorption capacity of nut shell activated carbon refers to the amount of contaminants it can adsorb. It is influenced by factors such as the type and concentration of impurities, temperature, and contact time. Understanding the adsorption capacity is crucial in determining the quantity of nut shell activated carbon required for a particular application.

How Do You Regenerate Active Carbon?

Depends on what you are using it for. Activated charcoal adsorbs many hydrocarbons and odor causing substances.

You can reactivate the charcoal by heating it in an oven at 200°C (400°F).

Do NOT put the plastic cartridge in the oven!

Plastic will melt and even burn at this temperature.

If your activated charcoal in in a cartridge you can open up, then remove the charcoal and spread I'd on a baking sheet. Bake it in the oven for about 10 min.

Different hydrocarbons and odor causing chemicals have different vaporization temperatures. You might get good results just heating the filter to 100°C if the majority of adsorbed chemicals have a low vaporization temperature.

Activated Carbon (Charcoal) can adsorb so well because the granules are very porous, so they have a very large surface area. Eventually these pores can become plugged by stuff that will not vaporize readily. Then it is time to replace the charcoal.
