Biodiesel Definition for Starters
In layman’s term biodiesel definition is a renewable fuel made from vegetable oils, animal fats and recycled waste oil.
Biodiesel refers to mono-alkyl esters of fatty acids coming from animal fats or vegetable oils.
Biodiesel fuel is produced from renewable resources which go through transesterification. This is a chemical procedure which separates the glycerol molecule and methyl which has been combined with alcohol to remove glycerin. Biodiesel can be made from methanol or ethanol that is used with a catalyst such as Potassium hydroxide or sodium hydroxide.
We can define biodiesel as liquid or gaseous fuel which is most importantly used as a transport sector that is produced from biomass.
Biofuels can be classified based on the basis of technology on the process of its production. It is based from first-generation biofuels (FGBs), second-generation biofuels (SGBs), third-generation biofuels (TGBs) and forth-generation biofuels.
The FGBs may refer to biofuels that are made from sugar, starch, vegetable oils or tallow. The SGBs are made from non-food crop, wheat straw, corn, wood, solid waste and energy crop, examples of SGBs are bio-oil, bio-alcohols and more. While the TGB’s came from algae and examples of this are vegetable oil and biodiesel.
And finally the fourth-generation biofuels are derived using the advanced technology converting vegetable oil and biodiesel to form bio-gasoline.
Unlike biofuels which are made from vegetable oils and animal fats, biomass is derived from different energy sources such as garbage, waste, wood and alcohol gasses and is carbon, hydrogen and oxygen based.
As biofuels have FGB’s to fourth-generation biofuels, biomass has a number of types to become a renewable energy source. As the energy is being released, it will be converted into another form such as heat or electricity or may be transformed into another form such as combustible biogas or liquid biofuel.
Biomass uses different conversion technologies such as thermal conversion in which the heat is the dominant mechanism to convert biomass into another chemical form. These are just some of the differences between biofuel and biomass. We can create energy with the use of bioethanol and biodiesel from biomass.
Bioethanol fuel or simply ethanol fuel is an alcohol made by fermenting the sugar and starch components of fermentation. Ethanol are widely used as a gasoline additive to improve octane and improve vehicle emissions and sometimes used as a fuel for vehicles in its pure form. Obtaining this information, you are now aware of the differences between biodiesel and bioethanol.
In addition Vegetable oil is also an alternative fuel for diesel engines. Some of these are SVO, WVO, PPO.
WVO an acronym for waste vegetable oil is the usual starting point of the product for making biodiesel.
For biodiesel it filters about 600 microns as the smaller particles tend to settle throughout the process. And the use of waste vegetable oil as a fuel competes with some other uses of the commodity which technically have an effect on petroleum diesel’s price.
On the other hand pure plant oil or simply PPO differs from WVO as it is not a byproduct of industries. It is intended also to power special modified automotive engines and most of the diesel car engines are suitable for SVO or straight vegetable oil but with appropriate modifications.
And overall biodiesel does not only save the environment from destruction but also saves money of the individuals.
