Heycarbons Nut Shell Impregnated Activated Carbon Manufacturer From China
Nut Shell Impregnated Activated Carbon
Heycarbons coconut shell impregnated activated carbon uses high-strength coconut shells as raw materials. After activation with steam, it forms a rich microporous structure.
Then, through chemical impregnation (KOH, NaOH, or FeCl₃), it is endowed with higher reactivity and selective adsorption capacity.
Characteristics of Nut Shell Impregnated Activated Carbon
Raw Material:
- Mainly made from nut shells.
- Besides coconut shells, there are also apricot shells, peach shells, palm shells, walnut shells, etc.
Production Process
- Heycarbons nut shell activated carbon is made from carefully selected nut shell.
- Through carbonization and steam activation.
- And impregnated with a specific chemical solution.
Advantages
- Nutshell granular activated carbon: low ash content, high strength, and high CTC.
- It has a lower cost than coconut shell activated carbon and can be used as a substitute for coconut shell activated carbon.
Comparison of Pores
- The proportion of micropores in activated carbon made from different raw materials (nut shells):
- Coconut shell > apricot shell > peach shell
Comparison of Strength
- Comparison of strength of activated carbon made from different raw materials (nut shells):
- Coconut shell > apricot shell > peach shell ≈ palm shell

Walnut shell
Pore Comparison of Nut Shell Activated Carbon
Pores Structure – Coconut shell
- Coconut shell activated carbon has the most developed micropores.
Pores Structure – Apricot shell
- The pore size distribution of apricot shell activated carbon falls between that of peach shells and coconut shells.
- It possesses a high proportion of micropores as well as a certain number of mesopores, resulting in a relatively balanced adsorption capacity.
Pores Structure – Peach shell
- Peach shell activated carbon has fewer micropores and more mesopores than apricot shell activated carbon.
Technical specifications of nut shell activated carbon
The standard technical specifications of the nut shell activated carbon (before impregnation) are as follows:
- Size: mesh 4*8 ,6*12, 8*30 , 8*16 ,12*40 ,30*60 , 80*150
- Iodine value: 900-1100 mg/g
- CTC: 40-80%
- Strength: 95-98.5%
- Bulk density: 0.45-0.55 g/cm3
- Ash: 5-8 %
- Moisture: 5% max.
- PH: 8-11

Application of Impregnated Activated Carbon From Nut Shell
Nut Shell Activated Carbon For Phosphorus Removal in River Water/Soil Improvement
Peach shell activated carbon impregnated with ferric chloride (FeCl3).
The functions of ferric chloride FeCl3 impregnated activated carbon from peach shell:
➡ Provides Fe³⁺ active sites → binds with phosphate, sulfides, and organic pollutants to form stable precipitates
➡ Activated carbon itself adsorbs organic matter/odor substances
Applicable Fields and Main Objectives of Peach Shell Activated Carbon Impregnated FeCl3
River water treatment (elimination of eutrophication and black odor)
- Phosphorus removal (PO₄³⁻)
- Removal of sulfides / black odor (H₂S, S²⁻)
- Reduction of COD / Removal of odor and organic matter
FeCl3 – impregnated peach shell activated carbon with an iodine value ≥ 800 mg/g is suitable for moderately polluted rivers.
Soil Improvement
- Remediation of Excess Phosphorus
- Fertilizer Damage Control
- Sulfide Rot Odor
- Risk of Excess Nutrient Leaching
- Soil Structure Improvement
Iron-Impregnated activated carbon is most needed for soils with excessive phosphorus.
Nuclear-grade Nut Shell Activated Carbon For Fluoride Wastewater Adsorption
FeCl3 Impregnated Nut Shell Activated Carbon For Fluoride-18 Wastewater Removal
Nuclear-grade activated carbon is used to adsorb fluoride-18 from wastewater. The raw materials are usually coal or nut shells, with a relatively small particle size (powdered carbon is also used). The direct adsorption capacity is relatively low, around 0.5%.
Therefore, modification of activated carbon is recommended. Impregnation with ferric chloride offers the best cost-effectiveness, while lanthanum nitrate is the most effective. The impregnation amount is usually no more than 10%.
Activated carbon parameters: We recommend customers use coconut shell granular activated carbon, 30-60 mesh, with an iodine value ≥ 1000 mg/g min.
We recommend customers use it at a pH between 6.5 and 6.8 after washing for better results.
Nut Shell Activated Carbon for SO2 Adsorption in the Intake Filter of Fuel Cell Product
For SO2 adsorption, impregnated activated carbon is generally used. Customers can choose between alkaline compound impregnation or metal oxide impregnation as needed.
Nut shell activated carbon, after appropriate activation or surface modification (such as oxidation treatment), exhibits excellent SO₂ adsorption performance due to its well-developed microporous structure, which is well-matched to the SO₂ molecular size. Furthermore, the oxygen-containing functional groups introduced to the surface enhance chemisorption.
Adsorption effect of different raw materials of activated carbon on SO₂ gas: coconut shell > nut shell > anthracite > bituminous coal.
Nut shell activated carbon for SO2 removal, impregnated with KOH or NaOH?
When using activated carbon from nut shell/coconut shell to adsorb SO₂, the choice between impregnation with KOH or NaOH depends on the specific application requirements. Each has its advantages and disadvantages:
1. Advantages of impregnation with KOH:
Higher reactivity: KOH is slightly more basic than NaOH, thus reacting with SO₂ more efficiently.
Easier oxidation: KOH reacts with SO₂ to produce potassium sulfite (K₂SO₃), which can be easily converted to potassium sulfate (K₂SO₄) under the action of oxygen. This reaction is generally smooth.
2. Advantages of impregnation with NaOH:
Lower cost: NaOH is cheaper than KOH, making it potentially more economical for large-scale applications.
Better stability: NaOH reacts with SO₂ to produce sodium sulfite (Na₂SO₃), and the subsequent oxidation reaction produces sodium sulfate (Na₂SO₄). This conversion is more stable, and the resulting sodium sulfate can be stored more stably.
3. Comparison:
Reaction Efficiency: KOH generally has higher reaction efficiency, especially at low temperatures where its reaction rate with SO₂ is faster.
Economy: Although NaOH has a slightly slower reaction rate, its lower cost makes it suitable for applications with tighter budgets.
Environmental Adaptability: The reaction of KOH is more susceptible to environmental factors such as temperature and oxygen concentration, while NaOH maintains better reaction stability under a wider range of conditions.
Summary:
Impregnation with KOH is suitable for applications requiring efficient SO₂ removal and a fast reaction rate.
Impregnation with NaOH is suitable for cost-sensitive applications or applications with lower reaction efficiency requirements.
Customers can choose the appropriate activated carbon impregnation solution based on their actual application needs.
