The advantages of activated carbon business

Our batch-type, fluidized bed reactor produces high-quality activated carbon.

We use our own unique, batch-type, fluidized bed reactor, to efficiently produce a stable, uniform, high-quality activated carbon. The operating principle of this incinerator is also found in our proprietary batch-type fluidized reactivation furnace, used to reactivate used activated carbon for economical reuse.

Our unique technologies adjust the diameter and volume of pores on the surface of activated carbon.

Activated carbon granules have lots of pores on their surfaces. By controlling the pores’ diameters and volumes, the performance of activated carbon can be enhanced. Our unique technology and extensive experience enable us to control the diameter and volume of the activated carbon pores, for tailor made meet to the application, allowing us to produce enhanced function activated carbon.
