Catalysts Product details

De-NOx catalysts/De-DXNs catalysts

The de-NOx catalyst reduces and eliminates nitrogen oxide generated through power plants and incineration.
The de-DXNs catalyst breaks down and eliminates dioxins generated through garbage incineration. Both catalysts contribute to environmental cleansing, and they are expected to gain increasing attention in coming years.
SCI is a manufacturer of titanium oxide, which is a primary raw material for these catalysts. We are the only manufacturer that can provide technological consistent from raw materials to catalysts products. We are confident that we have a product to suit your particular need, and we welcome your inquiries.

De-NOx catalysts/de-DXNs catalysts

  • SCI’s de-NOx catalyst technology is highly valued and has acquired the following accolades.
  • ◯We obtained an Important Technology Research and Development Fund Grant from the Ministry of International Trade and Industry. We achieved desired results and were certified as successful.
  • ◯We were awarded the 33rd Chemical Technology Prize by the Kinki Chemical Society, Japan.
  • ◯Our "development of the selective catalytic reduction catalyst by ammonia" was awarded the Technology Prize by the Catalysis Society of Japan in 1989.
