Fixed Carbon: This is the most important indicator of quality. Higher fixed carbon indicates better charring and higher energy content.
Premium: >75–80% (suitable for industrial use and activated carbon).
Standard: >70–75%.
Moisture Content: Low moisture content is crucial for a clean, efficient burn.
Maximum: Typically 8% or less.
Ash Content: The amount of non-combustible residue left after burning. Lower ash content is preferred.
Maximum: 3.5% or less.
Volatile Matter: The amount of combustible gases released during burning. Lower is better for industrial applications.
Maximum: 15% or less.
Calorific Value: The energy content (higher is better).
Net Calorific Value (NCV): Typically 6,500–7,000 kcal/kg.
