CG carbon’s activated carbon production process

Raw Material Selection: The Foundation of Quality

The process begins with sourcing premium-quality coconut shells. We prioritize:

• Sustainability: Using a renewable byproduct of the coconut industry, reducing environmental impact.
• High Carbon Content: Ensuring superior adsorption properties.
• Minimal Contaminants: Selecting shells with low ash content to maintain purity.

The Carbonization Process

Carbonization is the initial transformation stage where coconut shells are heated in a controlled, low-oxygen environment. This process:

• Removes Volatile Compounds: Eliminates unwanted organic materials.
• Forms Charcoal: The base material for activated carbon.
• Enhances Structural Strength: Provides a durable foundation for further processing.

Activation: Unlocking Porosity

Activation is the key step that differentiates raw charcoal from activated carbon. We use two primary methods:

1. Steam Activation

• Involves exposing the carbonized material to superheated steam at temperatures of 800–1100°C.
• Creates a vast network of micropores, increasing surface area and adsorption capacity.
• Ideal for applications like water purification and gas filtration.

2. Chemical Activation

• Uses chemical agents such as phosphoric acid or zinc chloride to open up pores.
• Conducted at lower temperatures (400–700°C).
• Preferred for specific applications requiring different pore structures, such as pharmaceutical use.

Quality Control Measures

At CG Carbon, every batch undergoes rigorous quality testing to ensure consistency and performance. Our quality control includes:

1. Iodine Number Test

• Measures adsorption capacity by determining the amount of iodine the carbon can absorb.
• Higher iodine numbers indicate better performance in purification processes.

2. Ash Content Analysis

• Ensures low ash levels for enhanced efficiency and longer service life.

3. Hardness Test

• Evaluates the durability of activated carbon to withstand handling and use in industrial applications.

4. Moisture Content Check

• Prevents excessive moisture, which can affect adsorption performance.

5. pH and Purity Testing

• Ensures the activated carbon is free from harmful residues that may interfere with application performance.

Packaging and Distribution

Once the activated carbon meets our stringent quality criteria, it is carefully packaged to maintain its integrity during transportation. We offer:

• Custom Packaging Solutions: Tailored to meet specific industry requirements.
• Secure Sealing: To prevent contamination and moisture absorption.
• Bulk and Small-Scale Supply Options: Catering to different business needs.
