What is the Catalyst?

The excellent catalysts purify automotilve emission and protect the environment.

We hold approximately 40% of the domestic market share in automotive catalysts and 10% of the world market share.

We developed globally competitive automotive catalytic technologies such as the world's first LNT catalyst. Our technologies have been highly evaluated and gained continuing supports and trusts from OEMs.

What is the catalyst?

“Cleaner than the air.” The passion made us develop the catalysts.

3way Catalysts detoxify the harmful exhaust emission; CO, HC, and NOx.
The CO is to be oxidized into the CO2,the HC is turned in to H2O and CO2, and the NOx is deoxidized into nitrogen.

Mechanism of the automotive catalyst
Automotive catalysts are placed near the engine and under the floor. The outer shape is monolith and the inside has honeycomb cells separated with thin walls. Harmful component such as carbon hydride, 3way Catalysts detoxify the harmful exhaust emission; CO, HC, and NOx. The CO is to be oxidized into the CO2,the HC is turned in to H2O and CO2, and the NOx is deoxidized into nitrogen.
