We will reveal why powdered activated carbon is preferred in many industrial processes and how its microscopic structure gives it outstanding efficiency. Join us on this journey to discover the secrets of powdered activated carbon!
What Is Activated Charcoal Powder?
Powdered activated carbon is a finely ground form of activated carbon, with a particle size generally less than 0.177 mm (80 mesh). This material is characterized by its enormous surface area and high adsorption capacity, making it an extremely effective adsorbent for a wide range of contaminants.
Powdered activated carbon can be produced from a variety of raw materials, such as coconut shells, charcoal, wood and other organic materials. The activation process involves heat treatment of these raw materials under anaerobic conditions, followed by physical or chemical activation that creates a complex porous structure.
One of the most outstanding features of powdered activated carbon is its immense internal surface area, which can reach up to 1500 m²/g. This vast area, together with its microporous structure, allows it to effectively capture molecules of various sizes, from organic compounds to heavy metals.

The production of powdered activated carbon is a meticulous process involving several key steps:
- Selection of raw materialsCarbon content: Materials with high carbon content are chosen, such as coconut shells, charcoal or wood.
- CarbonizationThe raw materials are heated under anaerobic conditions at high temperatures (400-900°C) to eliminate volatile compounds.
- ActivationIt can be physical (using high temperature steam or CO2) or chemical (using agents such as phosphoric acid or zinc chloride).
- GrindingThe activated carbon is ground to a fine powder.
- RankingParticle size separation: Particles are separated by size to ensure uniformity of the final product.
- Quality control: Tests are conducted to verify the performance of powdered activated carbon.
This carefully controlled process ensures that the powdered activated carbon has the necessary characteristics for your specific applications.

Frequently Asked Questions
The main difference is in particle size. Powdered activated carbon has smaller particles (less than 0.177 mm), which allows faster adsorption, but can be more difficult to separate from the treated medium.
Although in some cases it can be regenerated, it is not as common or as efficient as the regeneration of granular activated carbon.
Major industries include water treatment, air purification, food industry, gold recovery and industrial wastewater treatment.
The dose is determined by laboratory tests and pilot studies, considering the type and concentration of contaminants, the contact time and the characteristics of the water or air to be treated.
Powdered activated carbon is not toxic in itself, but its handling may generate respirable dust. It is recommended to use appropriate personal protective equipment during handling to avoid inhalation of particles.
