Resin-Based Spherical Activated Carbon

### Advantages of Spherical Activated Carbon

Spherical activated carbon is a material with extensive advantages in various applications, especially in the development of polymer-based spherical activated carbon. Compared to traditional pitch-based and coal-based spherical activated carbon, polymer-based spherical activated carbon exhibits a series of advantages:

1. **High Carbon Content and Low Ash Content**: The high carbon content and low ash content of polymer materials contribute to the purity and performance of the activated carbon.
2. **Good Compressive Strength**: The polymer-based materials provide spherical activated carbon with higher compressive strength, enhancing its durability in various applications.

#### Advantages of Phenolic Resin-Based Spherical Activated Carbon
1. **Simple Process**: The preparation process of phenolic resin-based spherical activated carbon involves the addition of curing agents and pore-forming additives, making the production process relatively simple.
2. **Low Cost**: The production cost is relatively low, providing an economic advantage in commercial applications.
3. **Easily Controlled Pore Size Distribution**: By adjusting the pore-forming additives, the pore size distribution of the activated carbon can be precisely controlled to meet different application needs.

#### Advantages of Ion Resin-Based Spherical Activated Carbon
1. **High Strength**: Ion resin-based spherical activated carbon has higher mechanical strength.
2. **Free of Impurities**: The preparation process avoids the introduction of impurities, resulting in a final product of higher purity.
3. **High Catalytic Activity**: This material exhibits high catalytic activity in catalytic applications.

#### Advantages of New Synthesis Methods
Since the 1990s, scientists have developed methods of synthesizing spherical activated carbon using various polymer materials, which do not require melting and carbonization. This further simplifies the production process and enhances product performance.

In summary, polymer-based spherical activated carbon, particularly phenolic resin-based and ion resin-based spherical activated carbon, demonstrates excellent physical and chemical properties, showing great potential for a wide range of applications.

Granular activated carbons are made from rigid raw materials, giving the necessary hardness to avoid excessive losses due to attrition and handling. They present large internal surface of pore structure, ensuring high adsorption power in specific purposes and uses. They are used in fixed or moving beds as columns where the liquid or gas passes through and gets purified. They can be used in liquid or gas phase continous adsorption process and offer unusual economy in cases where carbon regeneration is favorable. In liquid phase applications they remove colloids and organic substances that give undesirable odors, colors and taste to the products. They are efficiently used for water dechlorination in processes which require super chlorination as well as the removal of organic substances from the water. In vapor phase application they participate in the solvent recovery, adsorption of colors, purification of carbon di-oxide and catalyst support. They are also used to reduce the COD and BOD in effluent waste water.

Granular activated carbon is produced from coconut shell charcoal by the process of steam activation. The coconut shell charcoal is fed into the rotary kiln and activated by steam at high temperatures resulting in the evaporation of impurities and opening up of pores on the surface. The resultant big particles are then crushed and sieved to get the desired particle size.

Our main grades of granular activated carbon are given as under. We can customize the iodine value as well as the particle size according to your requirements

Our Powder activated carbon is manufactured using pure pine wood which is an excellent base for manufacturing activated carbons with good adsorption power.

The steam activated process is done by activating the charcoal in a rotary kiln by heating at high temperatures by steam. The activated carbon that comes out from the kiln is called unwashed activated carbon. These unwashed activated carbon has higher ash and iron content. This is reduced by washing the unwashed activated carbon with acid (HCl / H2SO4) and purified water. This results in reduction of ash content to as low as 1% and iron as low as 50 ppm.

The gradation of different qualities of activated carbon is done on the basis of Methylene blue value and iodine value. The iodine value is a better test as the particle size of iodine molecule is small enough to penetrate the smallest of pores. We can relate the iodine value of activated carbon directly to its surface area because of the above fact.

Water purification

Among its numerous sources, coconut shells have gained significant attention as a sustainable and efficient raw material for producing high-quality activated carbon. Coconut shell-based steam-activated Carbon is mainly used for the removal of chlorine, organic contaminants, color and odor from drinking water to make it suitable for human consumption. Being microporous in internal structure, coconut shell activated carbon is well suited for organic chemical adsorption, including volatile organic chemicals.
- One of the prominent applications of coconut shell-based activated carbon is in water treatment processes. It effectively removes impurities, organic contaminants, and heavy metals, ensuring clean and safe drinking water.
- It acts as a decolorizing agent, removing impurities and unwanted odors from edible oils, beverages, and food products finding its application in the food and beverage industry. Additionally, it is employed in the purification of sugar syrups, ensuring high-quality and clear syrup for various confectionery and beverage manufacturing processes.
- It serves as an excellent adsorbent in the production of drugs, where it eliminates unwanted impurities, colorants, and traces of heavy metals making it ideal choice in pharmaceutical industry too. The high purity and porosity of coconut shell-based activated carbon make it a preferred choice for pharmaceutical manufacturers to ensure product quality and safety.

We are supplier and exporter of Activated Carbon.

Granular Activated Carbon Products range from the size 0.2mm to 3.75mm. Granular Activated Carbon has relatively larger particles size compared to powdered activated carbon and consequently, presents a smaller external surface. Powdered Activated Carbon Powdered Activated Carbons are small activated carbon particles, with a size that is predominantly less than 0.075 mm.
