What is biodiesel? Biodiesel is an alternative renewable fuel made from plant and animal oils that is used in diesel engines. It has been shown to reduce emissions by 75% on average compared to petroleum diesel. In 1900, Rudolf Diesel demonstrated his compression ignition engine at the World’s Exhibition in Paris. In that prototype engine [...]
Biodiesel is nontoxic and poses little or no health risk to humans. Vehicles that run on biodiesel emit less sulfur dioxide (SO2), particulate matter (soot), carbon dioxide (CO2), with fewer heavy Hydrocarbons (HC) and Polycyclic Aromatic Hydrocarbons (PAH). Biodiesel does not contain sulfur so it will not contribute to sulfur dioxide emissions that result in [...]
Biodiesel production is the act of producing the biofuel, biodiesel, through either transesterification or alcoholysis. The process involves reacting vegetable oils or animal fats catalytically with a short-chain aliphatic alcohols (typically methanol or ethanol). The major steps required to synthesize biodiesel are as follows: Feedstock pretreatment If waste vegetable oil (WVO) is used, it is [...]
