Activated Carbon
Molecular Weight: 12.011
CAS Number: 7440-44-0
Chemical Name: Activated Carbon
Activated carbon is a porous material that removes organic matter from liquids and gases through a process known as adsorption.
It is used to describe generally organic material that has been heated to temperatures above 315 °C or heated first with a strong acid and then to temperatures above 232 °C.
The reason why Activated Carbon is preferred is that, during the activation process, it increases the surface area of each particle, making it a reliable adsorbent. In this way, microscopic pores are formed.
There are 3 types of activated carbon.
- Coal based Activated Charcoal
- Wood based Activated Charcoal
- Coconut shell based Activated Charcoal
The most commonly used of these is coal-based. The wood-based one has a certain usage rate in the industry. However, coconut-based activated carbon is slowly gaining usage in the industry.
Other Names Are As Follows;
- Carbon
- Graphite
- Powder Form
- Granular Form
- Mineral Carbon
- 7440-44-0
- Activated carbon
- Coal, Active
- Activated Charcoal
- Adsorbent
- Adsorbit
How is it produced?
The production of this chemical can be done from a wide variety of organic materials rather than coal.
There are 3 forms of Activated Carbon. These are Powder (PAC), Granular (GAC) and Pelleted forms.
The powder form has an average particle size of only 20 microns. Therefore, it becomes extremely fine in particle size. For this reason, powdered activated carbon can fly with the slightest air flow. Activated carbons that fly have the ability to cover every place.
The production process is divided into two groups: partial combustion process and pure pyrolysis process.
What are the Physical and Chemical Properties of Activated Carbon?
It is a black chemical used to increase absorbency. It can cause an explosion if not properly cooled after production.
If heated, it heats up slowly and can ignite in air.
It is in black powder, granule and pellet form. It is odorless.
It can also have a steel gray color. It feels oily. It is an odorless solid.
Its melting point is higher than 3500 °C.
The boiling point is higher than 4000 °C.
In terms of solubility, it is insoluble in water and organic solvents.
The density is between 2.00 and 2.25.
