Many countries around the world are involved in the growing use and production of biofuels, such as biodiesel, as an alternative energy source to fossil fuels and oil. To foster the biofuel industry, governments have implemented legislations and laws as incentives to reduce oil dependency and to increase the use of renewable energies. [117]
Both HVO diesel (green diesel) and biodiesel are made from the same vegetable oil feedstock. However the processing technologies and chemical makeup of the two fuels differ. The chemical reaction commonly used to produce biodiesel is known as transesterification. [2] The production of biodiesel also makes glycerol, but the production of HVO ...
Biodiesel is a liquid fuel composed of vegetable oils and or animal fats. To create the gasoline itself, these subsequent liquids are combined with alcohol. Biodiesel is used to fuel compression ignition engines, otherwise known as diesel engines. The most common product of biodiesel is B20, a 20:80 blend: 20% biodiesel to 80% petroleum diesel.
B20 biodiesel at the left and E85 ethanol at the right. Biofuels are also considered a renewable source. Although renewable energy is used mostly to generate electricity, it is often assumed that some form of renewable energy or a percentage is used to create alternative fuels.
Biofuel is a fuel that is produced over a short time span from biomass, rather than by the very slow natural processes involved in the formation of fossil fuels such as oil. Biofuel can be produced from plants or from agricultural, domestic or industrial bio waste.
Biodiesel has lower energy density than fossil diesel fuel, so biodiesel vehicles are not quite able to keep up with the fuel economy of a fossil fuelled diesel vehicle, if the diesel injection system is not reset for the new fuel. If the injection timing is changed to take account of the higher cetane value of biodiesel, the difference in ...
Biodiesel is similar to diesel but has differences akin to those between petrol and ethanol. For instance, biodiesel has a higher cetane rating (45-60 compared to 45-50 for crude-oil-derived diesel) and it acts as a cleaning agent to get rid of dirt and deposits. It has been argued that it only becomes economically feasible above oil prices of ...
PBRs is an easier system to be controlled compare to the raceway pond system, yet it costs a larger overall production expenses. [citation needed] The carbon emissions from microalgae biomass produced in raceway ponds could be compared to the emissions from conventional biodiesel by having inputs of energy and nutrients as carbon-intensive. The ...
