Which is Better, Coal-based Carbon vs Coconut Shell?

Activated carbon is a very important material in various industries, especially for purification and filtration of water, air, and chemicals.

The two most commonly used types of activated carbon are coal-based carbon and coconut shell-based carbon. However, which one is better between the two? This article will discuss the different characteristics and economic aspects of these two types of carbon to help you make the best choice.

1. Differences in Physical Characteristics

Each type of activated carbon has different physical characteristics, which affect its effectiveness in various applications.

• Density and Surface Area

  Coal-based carbon typically has larger pores and a different surface area compared to coconut shell-based carbon. This allows coal-based carbon to process larger molecules. Meanwhile, coconut shell carbon has more micro pores, making it more effective at removing organic compounds in water.

• Mechanical Strength

  Coal-based carbon generally has higher mechanical strength, which makes it more durable and stable under demanding conditions, such as high pressure or repeated use. On the other hand, coconut shell carbon despite having lower strength, remains strong enough to be used in many standard applications.

• Versatility in Various Industrial Applications

  Another reason why coal-based carbon is often chosen is its versatility in being used across a wide range of industrial applications. From air purification, gas treatment, to liquid filtration, coal carbon can adapt to the specific needs of each industry. In situations where multifunctionality and consistent performance are required, coal-based carbon often delivers better results compared to its alternatives. This makes it a top choice for many companies that prioritize efficiency and predictable results.

• Durability in Extreme Environments

  Industries that operate in extreme environments, such as under high pressure or extremely low temperatures, require materials that can withstand these conditions without sacrificing performance. Coal-based carbon has better durability in the face of these conditions, thanks to its stronger physical structure. This ensures that the carbon remains effective over a longer period of time, even when used in the most challenging operating conditions.

2. Economic Considerations

In addition to technical effectiveness, economic factors also play an important role in choosing the type of activated carbon.

• Price and Availability

  In general, coal-based carbon is cheaper because the raw material is more available especially in Indonesia and the production process is simpler. Coconut shell carbon tends to be more expensive due to a more specific production process.

• Total Cost of Ownership

  Coal carbon can be used for more purposes than coconut carbon but at a similar price. Especially, in terms of function and cost Coal Carbon is certainly more efficient to use for a long period of time.

Conclusion: Which is Better?

While coconut shell-based carbon has certain advantages, especially in terms of sustainability and specific applications such as water treatment, coal-based carbon offers a number of undeniable advantages in a broader industrial context. With higher mechanical strength, effectiveness in gas treatment, more competitive costs, flexibility in application, and better durability, coal-based carbon is often the more appropriate choice for companies seeking maximum performance at an effective cost.
