A strong base KOH or NaOH reacts with the oil and methanol to make soap and Biodiesel.
What is the impact of biodiesel. A decrease in DOC activity was seen after exposure to 150000 mile equivalent aging resulting in higher HC slip and a reduction in NO. The combustion of fossil fuels causes a dramatic increase in the greenhouse gas GHG emission to the atmosphere thus contributing significantly to the global warming. The environmental impacts of biodiesel substituting conventional diesel fuel are considered as beneficial.
2 Engines using biodiesel also emit significantly fewer pollutants with tailpipe particulate matter carbon. RME also has an impact on tailpipe emis-sions most notably increasing the NO x CO and HC emis-sions and reducing the PM emissions.

One of the greatest concerns over using biodiesel fuel has been regarding its quality and long-term effects on diesel vehicles. It is estimated that the additional ash from 150000 miles of biodiesel use would also result in a moderate increases in exhaust backpressure for a DPF. The recent California low carbon fuel standard is one example of that the impact of this and other such mandates policies has wide reaching implications for end users of biodiesel biofuels as well as huge implications for the feedstocks required to produce it.
22 Disadvantages of biodiesel. The use of biodiesel decreases the impact of global warming promotes European energy independence and supports EU agriculture. The biodiesel industry plays an important role in our countrys economy.
And making biodiesel from soybeans can reduce net emissions by nearly 80. Biodiesel B100 has similar impact providing the lubricating system is effective. At the same time biodiesel production boosts the US.
Biodiesel use may reduce greenhouse gas emissions. 21 Advantages of biodiesel The advantage of biodiesel as diesel fuel are its portability ready availability renewability higher combustion efficiency lower sulphur and aromatic content higher cetane number and higher biodegradability. Government considers biodiesel to be carbon-neutral because the plants that are the sources of the feedstocks for making biodiesel such as soybeans and palm oil trees absorb carbon dioxide CO2 as they grow.
