     Activated carbon rotary kiln is one of the pieces of equipment with a high utilization rate for processing activated carbon. activated carbon rotary kiln suitable for the activation of wood, sawdust, coal, walnut shell, apricot shells,  fruit stone, coconut shells, oil palms, bamboo, palm kernel, petroleum coke, and so on. Coconut and walnut shells are generally considered the best materials. Activated carbons from them have high strength and very fine pores. Most of these raw materials are cheap and easy to obtain, coupled with a simple production process and a broad market. These carbonaceous materials are converted into activated carbon through pyrolysis under high temperatures and certain pressure, and raw materials with different carbon content require different production ratios. Among them, some shell raw materials require de-ash pretreatment. An activated carbon rotary kiln has so many advantages such as advanced technology, simple operation, low carbon discharge, large production capacity, and high work efficiency.


1. Biomass Carbonization Process

Raw materials need to be carbonized through a carbonization furnace before entering the activated carbon rotary kiln. After the material enters the feed bin through the feeding port, it is fed into the carbonization furnace by the screw feeder. Depending on the inclination and rotation of the furnace body, the material moves slowly from the feeding port to the discharging port, gradually passing through the drying zone, the pyrolysis zone, and the carbonization zone. In this process, the carbonization furnace heats the material through thermal radiation so that the material is decomposed at high temperature to discharge non-carbon substances such as oxygen and hydrogen, and form fixed carbon with a skeleton structure and a certain strength to the greatest extent.

2. Carbon Activation Process

Carbon activation is mainly carried out in an activation furnace. Carbon activation refers to the use of water vapor, CO2, oxygen, and other oxidizing gases as activators, contacting with carbon at high temperatures so that the carbon surface is eroded and a developed pore structure is formed, which has a strong adsorption capacity.

3. Activated Carbon Washing Process

The activated carbon washing process can be divided into the acid washing process and the water washing process. Main purpose: reduce heavy metals contained in activated carbon; degrade TDS concentration; adjust PH value; reduce dust on activated carbon surface and pores.

4. Activated Carbon Regeneration Process

Activated carbon regeneration is the gasification reaction of adsorbed saturated activated carbon with water vapor and oxygen at high temperatures so that the organic matter blocked in the micropores is removed and its adsorption performance is restored.
