Exhaust Gas Purification Catalysts (Oxidation Catalysts, Deodorizing Catalysts, VOC Catalysts, Combustion Catalysts)

[Exhaust Gas Purification Catalysts product image] Metal Honeycomb Catalysts, Pellet Catalysts

We offer high performance exhaust gas purification catalysts.

We offer metal honeycomb catalysts and pellet catalysts that oxidize and decompose exhaust gases such as volatile organic compounds (VOCs), which are harmful to the human body and the environment, into harmless water and carbon dioxide.

Metal Honeycomb Catalysts

■Features

  • A honeycomb structure has been used to expand the surface area, enabling high catalyst reaction properties
  • The thin honeycomb structure wall enables a high aperture ratio with little pressure drop
  • The size can be more freely set than for ceramic honeycomb, with rectanglar, cylindrical, large and other shapes possible
  • Metal honeycomb is stronger and easier to handle than ceramic honeycomb

[Features of Metal Honeycomb Catalyst] 50µm thick Stainless steel foil is evenly coated with a high-performance oxidation catalyst / Catalyst structure with even and highly dispersed nano-sized Pt particles

■Shape

[Shapes of Metal Honeycomb Catalyst] Rectangular shape, Cylindical shpe, Toroidal shape
