  • A Catalytic Converter
    is a device used in automobiles to convert exhaust gas emitted from an incomplete combustion such as CO, NO and other hydrocarbons that are dangerous to health
    and environment into more environmentally friendly CO2, N2 and H2O
  • A catalytic converter consists of an insulated chamber containing a porous bed, or substrate, coated with catalytic material through which hot exhaust gas must pass
    before being discharged into the air
  • A catalytic converter is
    comprised of the catalyst called “three-way catalyst”, which are Platinum (Pt), Palladium (Pd)
    and Rhodium (Rh), coated on a honeycomb ceramic support.
  • The three-way-catalyst causes
    the oxidation and reduction reaction. It reacts with the heated exhaust gas and convert into
    CO2, N2, H2O the honeycomb ceramic support is the structure where the three-way catalyst
    coats on its surface so that the catalyst has high surface are in contact with the gas.
  • Three-Way Catalysts (TWC) are the main technology used to control emissions from petrol engines. The catalyst uses a ceramic or metallic substrate with an active coating incorporating alumina, ceria and other oxides and combinations of the precious metals - platinum, palladium and rhodium. Three-way catalysts operate in a closed-loop system including a lambda or oxygen sensor to regulate the air:fuel ratio on petrol engines
  • Catalyst poisoning occurs when the catalytic converter is exposed to exhaust containing substances that coat the working surfaces, encapsulating the catalyst so that it cannot contact and treat the exhaust. The most notable contaminant is lead, so vehicles equipped with catalytic converters can only be run on unleaded gasoline.
  • In the construction of converters
    manufacturers use ceramic extruding systems or (less frequently) metal-forming processes to generate honeycomb structures. After formation, these structures have their inner channels coated with a catalyst material before they are canned for deployment on an automobile
