Pitch-based activated carbon

• Most of the activated carbon used in Korea is produced from woody-based materials such as palm shells and wood and carbon-based materials through an inert gas atmosphere stage and a high-temperature oxidizing gas reaction
• Activated carbon is an amorphous carbon aggregate with developed pores
• Activated carbon has the property of adsorbing substances through physical and chemical interactions on its pore surfaces
• Effectively used to adsorb and remove harmful substances from water and atmospheric environments

SMARTKOREA Activated Carbon Features

Limitations of Existing Technologies

• At present, mainly general-purpose products are produced in Korea
• Pitch production technology for petrochemical processes is owned by Japan, Europe, etc.
• Pitch and high value-added products rely entirely on imports from Japan, Europe, etc.

Overcoming Limitations

• Technical independenceby securing core technology
• Economic impactthrough import substitution effec

Main application areas

• Adsorption towers in hazardous gas generating plants (compound production plants, incinerators,etc.)
• Hazardous gas purification filters in indoor areas where hazardous gases are generated
• For water treatment in water treatment plants
• Electrode materials for lithium-ion batteries
