  • Ceramic Honeycomb Substrates

    Ceramic Substrates, or Flow-Through Substrates, are extruded honeycomb monoliths containing thousands of parallel channels. Ceramic substrates are used at the heart of catalytic converters to help reduce exhaust emissions from diesel and gasoline-powered engines.

  • Diesel Particulate Filters (DPF)

    Diesel Particulate Filters (DPF)

    Diesel Particulate Filters (DPF), or Wall-Flow Filters, are used in trap systems that remove particulate matter (soot) from diesel exhaust emissions. These filters have a cellular structure with individual channels open and plugged at opposite ends...

  • Diesel Oxidation Catalysts (DOC)

    Diesel Oxidation Catalysts (DOC)

    The diesel oxidation catalyst (DOC), or Two-Way Catalyst, owes its name to its ability to promote oxidation of several exhaust gas components by oxygen, which is present in ample quantities in diesel exhaust...

  • Stationary Emission Catalysts

    Stationary Emission Catalysts

    Our solutions include CO oxidation catalysts (CO catalysts) to remove carbon monoxide (CO), VOC catalysts (VOC oxidation catalysts) to remove Volatile Organic Compounds (VOC), SCR catalysts (Selective Catalytic Reduction catalysts) to remove NOx (nitrogen oxides).

  • Automotive Emissions Catalysts

    Automotive Emissions Catalysts

    Our Solutions include catalyst formulations for gasoline, diesel and natural gas-induced emissions that perform significantly better than those previously available. This advantage comes from creating a catalyst that uses unique nanostructures with superior stability under prolonged exposure to high temperatures.
