Engine emission control

Engine Exhaust Catalysts


After the proliferation of the Clean Air Act in 1970, the catalytic converter for automobiles was introduced as probably the most important technology in History to clean air pollution worldwide. Removing Carbon monoxide (CO), Hydrocarbons (HC) and nitrogen oxides (NOx), the catalysts contributed substantially to the elimination or reduction of smog in major cities in the USA and Worldwide.

Over the last 40+ years, engine technology, electronics and also catalyst technology has advanced rapidly, and there is no longer such thing as a “one size fits all” technology for all engine emission applications. It is now critical to understand as much as possible about each engine emission application, to both size the catalyst appropriately, and to apply the proper formulation to remove the desired amount of CO, HC and NOx.

Applied Catalysts has the experience and technology to determine the best solution for each individual application. We manufacture oxidation catalysts (two way / CO & HC) and NSCR catalysts (three way/stoichiometric/CO, HC & NOx). We can also manufacture Diesel Oxidation Catalysts (DOC’s) and Diesel Particulate Filters (DPF’s).
