What does biofuel mean?
biofuel, any fuel that is derived from biomass—that is, plant or algae material or animal waste. Since such feedstock material can be replenished readily, biofuel is considered to be a source of renewable energy, unlike fossil fuels such as petroleum, coal, and natural gas.
What is biofuel made from?
Biofuels are transportation fuels such as ethanol and biomass-based diesel fuel that are made from biomass materials. These fuels are usually blended with petroleum fuels (gasoline and distillate/diesel fuel and heating oil), but they can also be used on their own.
What is the purpose of biofuels?
Replacing fossil fuels with biofuels—fuels produced from renewable organic material—has the potential to reduce some undesirable aspects of fossil fuel production and use, including conventional and greenhouse gas (GHG) pollutant emissions, exhaustible resource depletion, and dependence on unstable foreign suppliers.
What is biofuel and its types?
Unlike other renewable energy sources, biomass can be converted directly into liquid fuels, called “biofuels,” to help meet transportation fuel needs. The two most common types of biofuels in use today are ethanol and biodiesel, both of which represent the first generation of biofuel technology.
What are three types of biofuels?
There are three common types of biofuels, which include:
- Ethanol. Ethanol is pure alcohol or ethyl alcohol and is probably the most common alternative biofuel used in motor vehicles today.
- Biodiesel. Biodiesel is becoming more popular, and it mimics the traditional petroleum-based diesel.
- Biobutanol.
What are the types of biofuels?
The two most common types of biofuels in use today are ethanol and biodiesel, both of which represent the first generation of biofuel technology. The Bioenergy Technologies Office (BETO) is collaborating with industry to develop next-generation biofuels made from non-food (cellulosic and algae-based) resources.
What is a biofuel chemistry?
Biofuels are produced from natural products, often plant biomass containing carbohydrate. As biofuels are produced from plants, they are renewable and theoretically carbon neutral .
What are the main uses of biodiesel?
Applications
- Distribution.
- Vehicular use and manufacturer acceptance.
- Railway usage.
- Aircraft use.
- As a heating oil.
- Cleaning oil spills.
- Biodiesel in generators.
- Fuel efficiency.
What are biofuels PPT?
Biofuel is the fuel which is produced from organic products and wastes. Bioethanol is made from sugar, algae, wheat and sugar beet Biodiesel is made from vegetable oil, algal lipids, animal fats Biomethane can be produced from waste organic material, sewage, agriculture waste and domestic wastes.
Where does the energy for biofuels come from?
Bioenergy is energy derived from biofuels. Biofuels are fuels produced directly or indirectly from organic material – biomass – including plant materials and animal waste.
What kind of biomass is used for biofuels?
Traditional unprocessed biomass such as fuelwood, charcoal and animal dung accounts for most of this and represents the main source of energy for a large number of people in developing countries who use it mainly for cooking and heating.
Which is the most widely used liquid biofuel?
The most widely used liquid biofuels for transport are ethanol and biodiesel. Ethanol is a type of alcohol that can be produced using any feedstock containing significant amounts of sugar, such as sugar cane or sugar beet, or starch, such as maize and wheat.
What kind of plant matter can be used for biofuel?
Most plant matter is composed of cellulose, hemicellulose and lignin, and “second-generation biofuel” technologies refer to processes able to convert these components to liquid fuels. Once commercially viable, these could significantly expand the volume and variety of sources that could be used for biofuel production.
