Catalytic Converter Manufacturing

The catalytic converter is a marvel of chemical and technological engineering. It cleans gases passing through vehicles’ exhaust systems. Catalytic converters typically consist of a ceramic or metal honeycombed monolith substrate that carries precious metal catalysts. The coated substrate is wrapped in a protective thermal mat that expands when heated, securing and insulating the substrate, which is contained in a tough stainless steel shell and becomes a component in an engine exhaust system. As exhaust gases pass over the catalysts, chemical reactions occur that convert pollutants into harmless gases and water. Hydrocarbons combine with oxygen to become carbon dioxide. Nitrous oxides react with carbon monoxide to produce nitrogen and carbon dioxide, and with hydrogen to produce nitrogen and water vapor.

AP is a proven leader in the development and manufacturing of technologically advanced catalysts and catalyst systems. Our products meet and exceed the demands of the global emissions marketplace. As an innovator in an industry steeped with regulations and exacting requirements, our catalysts are engineered to the most stringent emissions standards set forth by engine-makers worldwide. Whatever the market – automotive or industrial, recreational or power equipment, AP is committed to satisfying the needs of each individual customer.

Creating an effective solution for each customer’s specific requirements is our goal. The very finest in technological advancements are used in the development and manufacturing of catalytic systems that meet or exceed global requirements for the control of combustion emissions from any fuel and all industries.
