The ultimate environmental solution
Katsuryokutan® activated carbon is an even more refined form of the activated carbon that has been the focus of so much recent attention. Besides being an effective water and air purifier with typical deodorizing and adsorbent features associated with activated carbon, UES’ Katsuryokutan® has been shown to very efficiently generate negative ions, absorb infrared radiation and electromagnetic waves, and prevent mites. Still more benefits from Katsuryokutan® await discovery. With absolutely no harmful effect on the ecosystem, we are convinced that effective and environmentally rational Katsuryokutan® is the ideal material for a world deeply concerned about environmental preservation.

Using Katsruryokutan® effectively
The Katsuryokutan® manufacturing process
Carbonized coconut shells are oxidized in an 800oC ? 1200oC steam environment, making the carbon structure more porous. This thermal process by which a more intricate pore structure and greater adsorption area is formed is called “activation“.
Difference between Katsuryokutan® and other products
| Katsuryokutan® | Wood and bamboo charcoals | |
| Coconut husks, sawdust and coals | Wood and Bamboo | Raw material |
| Activation by 750oC to 1200oC |
Hard charcoal 800oC or more Soft charcoal 400oC to 700oC |
Char Temperature |
| 800 to 1300 | 200 to 400 | Adsorption Area m2/g |
| Around 30A | Around 10A | Pore Distribution |
| Huge | Small (1/3 of Katsuryokutan®) | Adsorption Performance |
| 0.48 to 0.52 | Small | Appearance ratio in cc |
Superior performance
Katsuryokutan®'s performance is superior to other charcoal-based products. This superior performance is due to the difference in adsorption area: typical wood and bamboo charcoals cover 200 ? 400 m2/g while Katsuryokutan® covers an impressive 800 ? 1300 m2/g. The Katsuryokutan® manufacturing process employs precise industrial quality management, making it possible to consistently provide product of superior performance and quality. The complex surface structure of Katsuryokutan® is another important factor that separates it from other charcoal products. In sum, Katsuryokutan® is a perfect example of product development combining compactness and superior performance.
