Current practice of producing diesel from fogey give the sacks is in question regarding its sustainability. As the demand for diesel crude oils and petroleum, both(prenominal) of which argon do from fossil fuels, increases, the supplies are decreasing. Therefore it is crying we investigate secondary ways to power vehicles. This could substitute could be biodiesel. I chose this question because oil supplies are being worn and we are releasing 8.4 cardinal tonnes of Carbon Dioxide (CO2) into the Earth?s atmosphere each year, which is prejudicial for the environment. 27% of the US?s CO2 emissions are approach path from transportation, with 11% advent from trucks and public transportation. Research into feasible alternatives for fuel e.g. electric and nuclear number 1 have been conducted; however the technology needs to be developed further. Biodiesel however is a feasible alternative for which the technology currently exists. Biodiesel is a liquid fuel do from biolog ical ingredients such as new or apply veg oils or animal fat, and it is an alternative or running(a) to normal diesel. It is a cleaner burning replacement and is perishable and non-toxic. Biodiesel is produced from vegetable oils or animal fats through a serial matter of chemical reactions. The fats are known as triacylglycerols which are carbon, atomic number 1 and oxygen atoms that are bonded together. Glycerol (C3H5(OH)3) is manifest in entirely biodiesels.
Attached to it, are three unyielding chains containing carbon, hydrogen and oxygen; these are known as the fatty acids, as shown:(SEE ATTACHED FILE FOR PICTURE)To turn a fat into biodiesel a process called transesterificati on is used. This is when the fat is purified! and then reacted with m ethanol (CH3OH) or ethanol (CH3CH2OH) in the presence of a catalyst (a substance that increases the reckon of the chemical reaction) such as potassium hydroxide (KOH) or sodium hydroxide (NaOH). The triacylglycerols are separated into methyl esters (an... If you command to get a well(p) essay, order it on our website: OrderEssay.net
