Amount of alcohol allowed to be mixed with petrol in India is

commercial applications bioenergy biofuels making biofuels technological and industrial development

  1. 2.5 %

  2. 5%

  3. 10 %

  4. 10 - 15 %

Show answer
Correct Option: B
Explanation:
  • Alcohol(ethanol) is mixed with petrol because It enhances the octane contents in the fuel and hence acts as an anti-knocking agent(reduces knocking of the engines). 
  • Ethanol, when mixed with petrol, reduces the emissions from the vehicles.
  • The Amount of alcohol allowed to be mixed with petrol in India is 5%.
  • So, the correct answer is '5%'.

Amount of ethanol that can be added in petrol and used in conventional gasoline engines is

commercial applications bioenergy biofuels making biofuels technological and industrial development

  1. 5-10%

  2. 10-20%

  3. 15-25%

  4. 25-40%

Show answer
Correct Option: A
Explanation:

Amount of ethanol that can be added in petrol and used in conventional gasoline engines is about 5% to 10%. This is done because ethanol is a particulate-free burning fuel source. At many gas stations, E10 ethanol is widely used. It is a mixture of 10% ethanol with 90% gasoline.  

Thus, the correct answer is '5-10%.'

  1. 90 million $m^3$

  2. 150 million $m^3$

  3. 216 million $m^3$

  4. 300 million $m^3$

Show answer
Correct Option: D
Explanation:
  • Fuelwood is a fuel, such as firewood, charcoal, chips, sheets, pellets, and sawdust.
  • Fuelwood can is used for cooking and heating, and occasionally for fueling steam engines and steam turbines that generate electricity. It can also be used indoors in a furnace, stove, or fireplace, or outdoors in furnace, campfire, or bonfire.
  • In India, Fuelwood demand is about 300 million m3.
  • So, the correct answer is '300 million m3'.

  1. 2010

  2. 2020

  3. 2030

  4. 2040

Show answer
Correct Option: C
Explanation:
With the increased rate of population, the demand for natural energy resources has also increased over a period of time. 
Petroleum is a non-renewable source of energy because it takes thousands of years for the crude oil to be formed in the earth. 
The increasing demand for the use of petroleum is much faster than the rate at which petroleum is produced. 
So, the petroleum in the earth's reservoir is estimated to be finished in next few years by the end of 2030 as per the reports of IEA (International Energy Agency).
So, the correct answer is '2030'

  1. China

  2. Japan

  3. Brazil

  4. India

Show answer
Correct Option: C
Explanation:
  •  The most common grains that are used to produce ethanol are corn, barley and wheat. Ethanol is also called ethyl alcohol or grain alcohol.
  • It is usually blended with gasoline to create a fuel called gasohol. 
  • Brazil is the number one country in the production of gasohol through biotechnology.
  • Hence, Number one country in the production of gasohol through biotechnology in Brazil.
  • So, the correct answer is 'Brazil'.
