[jan]METHANOL-BLENDING IN PETROL

Question 1

Context?

Answer 1

-A study, in which methanol (M-15) was blended with petrol and used in the existing BS-IV standard
cars, found that the carbon dioxide emission had reduced substantially.(By ARAI,Pune)

-found that hydrocarbon emission reduced marginally, with a slight increase in nitrogen oxides.

Question 2

Why methanol?

Answer 2

• Methanol can be used as an energy producing fuel, transportation fuel and cooking fuel
• Methanol is a clean-burning fuel that produces fewer smog-causing emissions

-Methanol is most commonly produced on a commercial scale from natural gas. It can also be produced
from renewable sources such as biomass and recycled carbon dioxide.

-As a high-octane vehicle fuel, methanol offers excellent acceleration and power. It also improves
vehicle efficiency.

-High octane fuel :premium fuel (gasoline or petrol) -> The Octane rating is the ability of the fuel to resist engine knock – engine rattling sound that comes as a result of premature ignition of the compressed fuel in one or more cylinders.

Question 3

Methanol as an enduring solution to human energy needs?

Answer 3

• the thrown out C02 (greenhouse gas emission) both from using Methanol and while producing Methanol can be tapped back to produce Methanol.(Basically ek cycle tayar hoil input & output chi)
• C02 from steel plants, Thermal Power plants, Cement Plants etc. can be tapped in large quantities to produce Methanol.
