- 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 |
