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.

Question 44 - In a non-dilute absorber, graphical method is used to represent the process. In an X - Y coordinate system, X-axis represents mole of carbon dioxide / mole of water and Y axis represents mole of carbon dioxide / mole of nitrogen. The inlet gas stream consists of 8 mol % of carbon dioxide in nitrogen. (a) Find the S / G minimum as a slope that goes through the point (0, 0.0304) and (0.0000488, 0.086957). (b) Find the actual slope of operating line when it is 1.5 times the S / G minimum! (c) Find the value of x for inlet gas stream when y = 1640 x, y is mole fraction of carbon dioxide in nitrogen.

NATURAL GAS ENGINEERING - QUESTION 26.3 : The United States of America Energy Information Administration reports the following emissions in million metric tons of carbon dioxide in the world for year 2012 : Natural gas : 6799, petroleum : 11695, coal : 13787. Coal-fired electric power generation emits around 2000 pounds of carbon dioxide for every megawatt hour generated, which is almost double the carbon dioxide released by a natural gas-fired electric plant per megawatt hour generated. If 1 metric ton = 1000 kg and 1 pound = 0.4536 kg, estimate the total energy generated by natural gas in the world for year 2012, in gigawatt hour.

Question 86 - (a) Male with genotype GGmm and phenotype gray wingless mates with female with genotype ggMM and phenotype black winged in fruit flies. G is dominant to g in color. M is dominant to m in wing shape. If the actual distribution of the second generation of the fruit flies was as follow : 890 gray wingless, 900 black winged, 115 gray winged, 95 black wingless, calculate the recombination frequency betwen the two genes and distance in recombination units. Let 1 map unit = 1 % recombination. (b) A DNA molecule has 180 base pairs and 20 % adenine. How many cytosine nucleotides are present in this molecule of DNA?
