Caffeic Acid: An Efficient Antioxidant for Soybean Biodiesel Contaminated with Metals. System diagram for transesterification of food waste derived biodiesel. Biodiesel can be used in pure form (B100) or may be blended with petroleum diesel at any concentration in most injection pump diesel engines. Biodiesel, which can be mixed with petrodiesel for burning in diesel engines, has several positive features for use in engines, and are as follows: Petrodiesel contains up to 20% polyaromatic hydrocarbon, while biodiesel contains none, making it safer for storage.
The reaction is carried out in a fixed or fluidized bed.
PROPERTIES. The
Large-scale commercial production of biodiesel can therefore bring a huge amount of glycerol into the market.
Crude glycerol can be treated to produce different coproducts including feedstock for animal feeds or the production of value-added chemicals, depending on the glycerol purity (Yang et al., 2012).

A caustic stripping process can also be used to create a soap but results in significant yield loss and creates disposal issues.
can be made from many oils and fats such as
Biodiesel carries the name fatty acid methyl (or ethyl) ester, commonly abbreviated as “FAME.” A popular production method involves mixing waste vegetable oil or fat with the catalyst and methanol (or ethanol) in appropriate proportion. Biodiesel can be used in its pure form (B100) or blended with petroleum diesel. It should be noted that pure biodiesel contains less energy on a volumetric basis than petroleum diesel.
The main impacts due to the transesterification process stem from thermal and electrical energy demands, which can contribute as high as 30% to the total system GWP in the case of biodiesel production from beef tallow and poultry fat (Dufour and Iribarren, 2012). The standards for biodiesel in India are under formulation and are proposed to be based on standards adopted by European Union.
Blends of 20% biodiesel with 80% petroleum diesel (B20) can generally be used in

B20 with 20% biodiesel content will have 1% to 2% less energy per gallon than petroleum diesel, but most B20 users report no noticeable difference in performance or fuel economy. times greater than the actual fossil gross energy consumption. Petrodiesel (also called fossil diesel) is produced from the fractional distillation of crude oil between 200°C and 350°C at atmospheric pressure, resulting in a mixture of carbon chains that typically contain between 8 and 21 carbon atoms per molecule (Collins, 2007).

An alternative noncatalytic conversion route for biodiesel is under development in which transesterification of triglycerides is by supercritical methanol (above 293°C, 8.1 MPa) without a catalyst (Kusdiana et al., 2006). alternative to fossil diesel with a strongly positive energy and CO2 balance.
