Activated Carbon Furnace is the core equipment in the production of high-quality activated carbon. It provides the necessary thermal environment for the 碳化 和 启动 processes, transforming raw biomass or coal into porous activated carbon with a high adsorption capacity.

Due to increasing demand for water purification, air treatment, and energy storage applications, industries worldwide are investing in advanced activated carbon furnaces to ensure stable production, energy efficiency, and environmental compliance.

1. What is an Activated Carbon Furnace?

An Activated Carbon Furnace is a specialized high-temperature thermal system designed to process raw materials such as coconut shells, wood, nutshells, bamboo, coal, or petroleum coke. It operates under controlled atmosphere conditions to convert these raw materials into activated carbon.

The furnace can serve two primary functions:

1. Carbonization – Heating raw materials in a low-oxygen environment (400–700°C) to remove volatile substances and produce char.
2. Activation – Treating the char at higher temperatures (800–1000°C) with oxidizing gases (steam or CO2) to develop microporous and mesoporous structures, which greatly increase surface area.

2. Main Types of Activated Carbon Furnaces

2.1 Carbonization Furnace

• Used for the initial pyrolysis of raw materials.
• Operates in oxygen-limited conditions.
• Types: Batch carbonization furnace, continuous carbonization furnace, and rotary carbonization furnace.

2.2 Activation Furnace

• Used after carbonization to create pores.
• Steam or CO2 is introduced to react with carbon at high temperature.
• Types: Rotary activation furnace, vertical activation furnace, fluidized bed activation furnace.

2.3 Rotary Furnace for Activated Carbon

• The most popular type for large-scale continuous production.
• Features:
  • Rotating cylinder ensures uniform heating.
  • High throughput capacity.
  • Suitable for coconut shell activated carbon, coal-based carbon, and bamboo carbon.

2.4 Batch Activated Carbon Furnace

• Small-scale, cost-effective, and flexible.
• Suitable for laboratories or pilot production lines.

3. Structure of an Activated Carbon Furnace

A standard activated carbon kiln includes:

1. Furnace Body – High-temperature-resistant steel and refractory lining.
2. Heating System – Gas burners, electric heaters, or biomass fuel systems.
3. Temperature Control System – PLC or digital controllers.
4. Gas Supply System – Steam generators or CO2 pipelines for activation.
5. Cooling Section – Rapid cooling chambers to prevent spontaneous combustion.
6. Dust Collection and Exhaust System – Ensures compliance with environmental standards.

4. Working Principle of Activated Carbon Furnace

Step 1: Carbonization

Raw materials are fed into a carbonization furnace and heated at 400–700°C in limited oxygen. Volatile matter is driven off, producing char.

Step 2: Activation

The char is transferred into an activation furnace (such as a rotary furnace). High-temperature steam or CO2 reacts with the carbon:

• C + H2O → CO + H2
• C + CO2 → 2CO

These gas–solid reactions etch the carbon structure, forming micropores and mesopores.

Step 3: Cooling and Collection

Activated carbon is cooled in an inert environment and then collected for screening and packaging.

2. Energy Saving
   • Waste heat recovery systems reduce fuel consumption by 15–20%.
3. Uniform Product Quality
   • Precise temperature and gas flow control ensure stable pore structures.
4. Versatile Raw Material Adaptability
   • Capable of processing coconut shells, bamboo, coal, and other feedstocks.
5. Eco-Friendly Operation
   • Equipped with dust removal and exhaust treatment systems.

7. How to Choose the Right Activated Carbon Furnace?

1. Production Scale – Small labs may use batch furnaces; large factories require rotary kilns.
2. Raw Material Type – Coconut shells prefer rotary kilns; coal may use vertical furnaces.
3. Energy Source – Choose between gas, electricity, or biomass heating.
4. 自动化水平 – Advanced PLC systems reduce labor costs and improve stability.
5. Environmental Compliance – Ensure furnaces have gas scrubbing and dust filtration systems.
