Difference between carbon black and activated carbon

Difference between carbon black and activated carbon

The difference between carbon black and activated carbon both are important materials as adsorbing agents. The activated carbon is high technology material which is using in military sector and precision tools.

They have a high surface area compared to their volume, which allows the substance to absorb as much as it can. And call them paracrystalline carbon compounds .

Most important difference between those is that the surface-area-to-volume ratio of carbon black is lower than that of charcoal activated .Carbon black is an adsorbing agent that forms from the incomplete combustion of heavy petroleum products . and charcoal activated coal is an adsorbing agent that is derived from charcoal.

What is activated carbon?

Activated carbon also called charcoal activated coal, it is a very useful adsorbent. Du to their high surface area ,and high degree of surface reactivity.

The base materials for they are coconut shell, coal or wood ,each base material may offer a slightly different product, but it will generally function identically in different applications. Its a very economical solution for different industries because its easy to source.

Moreover, they are economical adsorbents for many industries such as water purification, food grade products, industrial gas purification, and petroleum.

Charcoal activated coal usage areas

It has a wide range of applications such as food, pharmacy, chemistry, petroleum, mine, nuclear, automobile, waste gas and cleaning of water.

Most of surface area, high surface reactivity ,fit pore distribution, mechanical durability are the properties sought in it.

Types of the activated carbon:

  • Granulated
  • Pelletized
  • Powdered 
  • Impregnated
  • Catalytic
