Questions Related to commercial applications

One of the country where alcohol has been very successfully used as motor fuel is?

commercial applications bioenergy biofuels making biofuels technological and industrial development

  1. U.S.A

  2. Brazil

  3. Japan

  4. Germany

Show answer
Correct Option: B
Explanation:
Alcohol has been used as biofuel in many countries especially Brazil. The alcohols that are used as biofuels are methanol, ethanol, propanol and butanol. Ethanol is most commonly used as biofuel. Brazil has highest production of ethanol as biofuel. Ethanol in brazil is produced from sugarcane. The bagasse of sugar cane i.e. residual cane waste is fermented to produce ethanol. In 2015/16, Brazil raised about 80 billion gallons of ethanol. Ethanol is the blended in gasoline and used as fuel for engines.
So, the correct answer is 'Brazil'.

L.P.G. cooking gas is

commercial applications bioenergy biofuels making biofuels technological and industrial development

  1. Low pressure gas

  2. Biogas

  3. Fossil fuel

  4. Low price gas

Show answer
Correct Option: C
Explanation:

As LPG gas is a fossil fuel, it comes from oil and gas wells. It is obtained by the refining of oil.

So the correct option is C.

Domestic cooking gas cylinder contains

  1. Coal gas

  2. Liquid petroleum gas

  3. Diesel oil

  4. Alcohol

Show answer
Correct Option: B
Explanation:
  • The domestic cooking gas cylinder contains Liquid petroleum gas.
  • Its composition is propane or butane or a mixture of both, are flammable mixtures of hydrocarbon gases used as fuel in heating appliances, cooking equipment, and vehicles.
  • So, the correct answer is 'Liquid petroleum gas'.

Gasohol was first used in

  1. 1970's

  2. 1980's

  3. 1940's

  4. 1800's

Show answer
Correct Option: C
Explanation:

Gasoline or petrol is a derivative product of petroleum distillation. The ethanol or ethyl alcohol is produced from fermentation and distillation of grains e.g., corn, barley, wheat. When gasoline is blended with ethanol it becomes Gasohol, the percentage is 90 and 10 respectively. It was first used in Nebraska 1940. It is used as an alternative fuel. Hence the first use of Gasohol was in the 1940s.

Hence, the correct answer is '1940's'.

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%.'

Fuelwood demand in India is

commercial applications bioenergy biofuels making biofuels technological and industrial development

  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'.

Mineral oil is

commercial applications bioenergy biofuels making biofuels technological and industrial development

  1. Mustard oil

  2. Petroleum

  3. Liquefied petroleum gas

  4. Palm oil

Show answer
Correct Option: B
Explanation:
Petroleum is dark coloured thick crude oil and is also called fossil fuel. It is known as mineral oil as it is procured during refining and extraction of crude oil.
A. Mustard oil is obtained from the seeds of the black and white mustard plant. These oils are edible vegetable oils. 
B. Petroleum is mineral oil.
C. LPG is prepared by oil refining or during natural gas processing. 
D. Palm oil is obtained from palm fruit. 
Hence, the correct answer is 'Petroleum'

Which one of the following is not a fossil fue;?

  1. uranium

  2. coal

  3. natural gas

  4. petroleum

Show answer
Correct Option: A

Revised data for petroleum depletion time is

  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'
