In automobile catalytic converter is used to reduce the
exhaust gases toxic. CO, HC, N are the major pollutant of
exhaust gases.
In petrol engine, it is used to reduce the pollutant like
CO, HC, N convert into CO2, H20, N2 by using catalyst like
platinum, metal rhodium.
In diesel it is used to reduce only CO, HC into CO2 and H2O.

Answer / tarun kumar

In case of gasoline engine catalystic convertor oxidises NO
present in the exhaust gases to NO2.
In case of diesel engine it removes the solid particulates
present in the exhaust gas.

Answer / anwar ashwak hussain

as the fuel having harmful
S,N2 etc.. upon combustion of
this fuel leads to produce
SO2, NO,CO n other
dangerous gases to reduce
their effect we have to
change these gases to SO3,
NO2, CO2,water vapor etc. by
using platinaum, rhodium like
catalyst to safe guard the
environment.

PETROLEUM ENGINEERING - QUESTION 25.2 : (a) The American Petroleum Institute gravity, or API gravity, is a measure of how heavy or light a petroleum liquid is compared to water. Let SG = specific gravity of petroleum liquid, and V = barrels of crude oil per metric ton. Given the formula for API gravity = 141.5 / SG - 131.5 and V = (API gravity + 131.5) / (141.5 x 0.159), find the relationship of SG as a function of V. (b) An oil barrel is about 159 litres. If a cylinder with diameter d = 50 cm and height h = 50 cm is used to contain the oil, find the volume V of the cylinder in the unit of oil barrel by using the formula V = 3.142 x d x h x d / 4. (c) First reference : 1 cubic metre = 6.2898 oil barrels. Second reference : 1 cubic metre = 6.37 oil barrels. What are the 2 factors that cause the difference in such reference data?
