  1. Euphorbia

  2. Beetroot

  3. Sugracane

  4. Pongarnia

Show answer
Correct Option: A
Explanation:

Jatropha is a member of the euphorbia family. One of its great selling points as a biofuel is the fact that growing it need not compete with the cultivation of food. The selling point as a bioenergy crop is that it grows in marginal, eroded land, and is resistant to drought. 

A petroleum plant is

  1. Sugarcane

  2. Maize

  3. Potato

  4. Euphorbia

Show answer
Correct Option: D
Explanation:
Euphorbia is a petroleum plant. It produces hydrocarbons known as terpenoids which are similar to petroleum. It belongs to Euphorbiaceae family. The latex of this plant can be converted to useful fuels. About 20 tonnes of dry matter per hectare per year is produced by this plant. The latex is converted into natural gas and gasoline. Gasoline is used as an alternative fuel in vehicles.
So, the correct answer is 'Euphorbia'.

Petrocrops are plants

  1. Grown near oil fields

  2. Used in refining crude oil

  3. Whose fossil remains formed crude oil

  4. From which petrol-like fuels can be derived

Show answer
Correct Option: D

Coal has been mainly formed by

  1. Bryophytes

  2. Pteridophytes

  3. Angioperms

  4. Algae

Show answer
Correct Option: A
Explanation:
  • Bryophytes are group of non vascular land plants including hornworts, liverworts and mosses. Peat is a fuel which is produced from dried bryophytes, typically sphagnum. Enormous deposits of peat is accumulated which is later converted into coal.
  • Hence coal has been mainly formed by bryophytes.
  • So,the correct answer is 'Bryophytes'.

The first petroplant discovered by Calvin was

  1. Copaifera longsdorfii

  2. Euphorbia lathyrus

  3. Jatropha

  4. Calotropis

Show answer
Correct Option: B
Explanation:
Calvin started his work on petroplants in 1977. Petroplants produce latex of long hydrocarbon chains which can be converted into petrol like products. He worked on Euphorbia lathyris. When he collected latex from the samples and analysed its composition by different methods like spectroscopy and chromatography, he found long chain hydrocarbons similar to petrol and other fuels. Euphorbia produces large amount of latex which is processed and converted to petrol like fuel.
So, the correct answer is 'Euphorbia lathyris'.

The energy obtained from biological resources is called as

commercial applications bioenergy biofuels making biofuels technological and industrial development

  1. Electrical energy

  2. Mechanical energy

  3. Bioenergy

  4. Life energy

Show answer
Correct Option: C
Explanation:

Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.

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

  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

commercial applications bioenergy biofuels making biofuels technological and industrial development

  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

commercial applications bioenergy biofuels making biofuels technological and industrial development

  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'.
