Nut shell activated carbon refers to activated carbon that is made from coconut shells, peach pits, apricot shells, and other types of nut shells. We generally select suitable nut shells, after being refined by carbonization, activation, superheated steam catalysis, and other processes, nut shell activated carbon can be produced.

Nut shell activated carbon is a common absorption material, the main functions of nut shell activated carbon include adsorption of harmful gases, decolorization, deodorization, water purification, and so on.

Our nut shell activated carbon solution can process various types of shapes and sizes, as a professional activated carbon machines supplier, we can offer customized-design of activated carbon plant, if you have any need, please feel free to contact us.

SHAPES: powdery, granular, spherical and columnar activated carbon.

SIZES: 1-2mm, 2-4mm, 4-8 mesh, 6-12 mesh, 8-16 mesh, 8-30 mesh, 20-40 mesh, 200 mesh, 300 mesh.

Nut shell applications:

With the advantages of good wear resistance, developed void, high adsorption performance, high strength, easy regeneration, and economic and durability, nut shell activated carbon is widely applied in domestic, industry, liquid phase adsorption, water purification, and gas phase adsorption. Especially suitable for power plants, petrochemical, oil refinery, printing and dyeing textile industry, food and beverage, medical water, electronic high-purity water, drinking water, industrial water reuse, and other industries. More effective adsorption of free chlorine, phenol, sulfur, oil, gum, pesticide residues, and other organic pollutants in water, residual chlorine, semi-dechlorination value, and for the recovery of organic solvents.

raw materials of nut shell activated carbon plant

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.

Nut shell activated carbon manufacturing process

The processing process of nut shell activated carbon mainly includes the following steps:

  1. Raw material preparation: in the preparation section, firstly clean nut shells and remove the impurities and residues. After cleaning process, nut shells raw materials wil be dries for further processing.
  2. Crushing and screening plant: the selected nut shell is broken to make its particle size meet the requirements of the subsequent process. The crushed nut shells are then graded by a screening device so that a uniform porous structure can be formed in the subsequent carbonization process.
  3. Carbonization process: carbonization process is the key step of nut shells activated carbon production line. At this stage, the screened nut shells are put into a carbonization furnace and pyrolyzed under high temperature conditions, so that the organic matter in the nut shells is converted into carbon. In the carbonization process, temperature, atmosphere and time need to be controlled to ensure the quality and yield of carbonized products. The carbonization process can be carried out by intermittent or continuous methods to adapt to different production needs.
  4. Activation process: the activation process is another key step in the production of activated carbon from nut shells. The activation treatment is to further improve the adsorption performance of activated carbon in nut shell. In the activation furnace, the carbonized products are reacted with water vapor or carbon dioxide to produce more micropores and mesoporous pores on the surface of the carbon. It is also necessary to control temperature, atmosphere and time in the activation process to obtain an ideal activated carbon structure.
  5. Washing and drying: after activation, some ash and impurities remain on the surface of activated carbon in the nut shell, which needs to be rinsed. The rinsing process generally uses acid-base solution or pure water to wash to remove impurities and ash on the surface of activated carbon. During the washing process, attention should be paid to controlling the temperature and concentration of the washing water to avoid damage to the activated carbon. The rinsed nut shell activated carbon needs to be dried to remove the water inside and improve its adsorption performance. The drying process is generally carried out by high temperature hot air drying equipment to accelerate the evaporation of water and remove the internal water.
  6. Finished product processing: after drying, the activated carbon of the nut shell was crushed and sieved again to obtain the particle size distribution meeting the requirements of use. This step is essential to ensure the performance of activated carbon in practical applications.
  7. Inspection and packing: the finished nut shell activated carbon needs to be tested for quality, including adsorption properties, ash, moisture and other indicators. Only the activated carbon that meets the quality standards can be sold from the factory. After the quality test is qualified, the activated carbon will be packaged to facilitate subsequent use and transportation, usually using plastic bags or woven bags for packaging to prevent the product from moisture and damage during transportation and storage.
