Swids Activated Carbon

Production Process

Our activated carbon is produced through two basic processes:

1. Carbonization: Precursors are subjected to high temperatures (400-850°C) to expel volatile components, removing non-carbon elements like hydrogen, oxygen, and nitrogen in the form of gases and tars.
2. Activation: The carbonized char undergoes activation to enhance pore size through:
   • Opening of previously inaccessible pores
   • New pore development by selective activation
   • Widening of existing pores at 900-1200°C

Activation Methods
Physical Activation

• Uses oxidizing gases such as air, carbon dioxide, and steam at high temperatures (650-900°C)
• Carbon dioxide provides pure nature, easy handling, and controllable activation
• Steam activation is 2-3 times more efficient than carbon dioxide with the same degree of conversion

Chemical Activation

• Involves mixing precursors with activating agents (NaOH, KOH, FeCl₃, etc.)
• Performed at lower temperatures (300-500°C)
• Provides benefits such as high microporosity, large surface area, and reduced processing time
