How Catalytic Converter Helps to Reduce Car Emission

Description:

A catalytic converter is a device fitted inside the exhaust pipe used to control the emission of the vehicle. By catalyzing a redox reaction, it converts toxic gases into less toxic pollutants. The conversion occurs upto 98%. It reduces the emission level of harmful gases by doing the reduction of nitrogen oxide into nitrogen and oxygen, oxidation of hydrocarbons into carbon dioxide and water, and carbon monoxide into carbon dioxide. To prevent environmental pollution, and prevent emission related issues of the vehicle, the catalytic converter must be kept in good order. – PowerPoint PPT presentation

Title: How Catalytic Converter Helps to Reduce Car Emission


1
HOW CATALYTIC CONVERTER HELPS TO REDUCE CAR
EMISSION?
2
Ignition of hydrocarbon-based fuel inside the
combustion chamber of an engine generates a huge
amount of environmental pollutants as byproducts.
3
Invention and integration of catalytic converter
in the car has significantly reduced the emission
level.
4
It helps to get rid of carbon monoxide, oxides of
nitrogen, and other kinds of pollutants and thus
prevents air pollution.
5
However, clogged or defective catalytic could not
do its job efficiently.
6
Any signs which show that the catalytic converter
has issues should not be overlooked.
7
Efforts should be made to remove the contaminants
and keep the catalytic converted clean.
8
COMPONENTS OF A CATALYTIC CONVERTER
9
Catalyst is a substance that induces or
accelerates a chemical reaction.
10
The catalytic converter uses certain types of
metallic catalysts which helps to convert toxic
pollutants to non-toxic gases.
11
Usually, modern car makers use noble metals like
platinum, palladium, and rhodium in the catalytic
converter.
12
A catalytic converter has two different types of
catalyst
13
  • REDUCTION CATALYST
  • OXIDATION CATALYST

14
Such components made of a ceramic complex
laminated with metallic catalysts like palladium,
platinum, or rhodium.
15
TYPES OF THE CATALYTIC CONVERTER
16
There are two different types of the catalytic
converter with distinct features.
17
TWO-WAY CATALYTIC CONVERTER
18
Such types of catalytic converters were widely
used during the 1980s.
19
Two-way catalytic converter could efficiently
convert carbon monoxide and hydrocarbons to
carbon dioxide.
20
  • 2CO O2 ? 2 CO2
  • HYDROCARBONS O2 ? CO2 H2O

21
However, it could not deal with oxides of
nitrogen which are solely responsible for the
smog and acid rain.
22
THREE-WAY CATALYTIC CONVERTER
23
Such types of catalytic converters can reduce the
emission of NO and NO2 which are solely
responsible for the acid rain.
24
It reduces the oxides of nitrogen to free
nitrogen which is not toxic.
25
  • Following reactions might be helpful to
    understand the reduction of oxides of nitrogen to
    free and non-toxic nitrogen.
  • 2 H2 2 NO ? 2 H2O N2
  • 2 CO 2 NO ? 2 CO2 N2
  • HYDROCARBON NO ? CO2 H2O N2

26
Besides, a three-way catalytic converter could
more efficiently deal with the carbon monoxide
and unburned hydrocarbons.
27
FINALLY
28
Catalytic converter plays a crucial role by
converting toxic environmental pollutants to
non-toxic free gases.
29
Any kinds of abnormalities in the catalytic
converters should never be neglected.
30
The root cause of such abnormalities should be
identified and repaired in time.
