Technical Information

Integrated one-step carbonization and activation system for sawdust, coconut fibre or shell, palm fibre, wood chips, bagasse and spent powdered carbon, with drying and regeneration options for spent powdered or granular activated carbon.

Composition and process

• One-step activation reduces the need for separate drying and carbonization stages.
• Recovered heat can support hot water, drying or steam generation.

Applications

• Activation of biomass and spent-carbon feedstocks.
• Drying and regeneration of spent powdered or granular activated carbon.

Key specifications

• Typical coconut-fibre feed ratio: 11 t per 1 t activated carbon; methylene blue >10–12 mL/0.1 g; iodine number 950–1100 mg/g.
• Production cost target ≤CNY 1,300/t; output 2–10 t/day; feed capacity 20–200 t/day.
• Factory height ≥8 m; approximately 500 m² floor area; electricity demand 70–100 kW/h; wet-basis yield 10:1 or 11:1.

Advantages

• Reduces separate drying and carbonization costs, with a high degree of automation and cleaner production.
