In today's scenario the populations continue to rise, meeting the demands of energy has become a growing concern for the global scenario and one of these solutions is to use biodiesel as an alternative fuel is explored along with its desirable fuel characteristics. The technological requirements for the process and production of Biodiesel are comparatively less cumbersome and their ability to feed an existing diesel vehicle without minor modifications or also make it a promising alternative fuel and is discussed. This report also covers attributes such as emissions, feed stocks, method of production, latest trends and the advantages and disadvantages of biodiesel.
The finite character of fossil fuels requires consideration of alternative fuels from renewable sources. The term biofuel refers to the liquid, gas and solid fuels predominantly produced from biomass. Biofuels include bioethanol, bio-methanol, biodiesel and biohydrogen. Biodiesel, defined as monoalkyl esters of vegetable oils or animal fats, is an attractive alternative fuel because it is respectful of the environment and can be synthesized from edible and non-edible oils.
Biodiesel is attracting increasing attention around the world because it is currently the only carrier of renewable energy that could directly replace diesel fuel in compression ignition engines. In addition, life cycle analysis (LCA) data for biodiesel suggest positive cumulative energy values compared to petroleum diesel (Vonortas and Papayannakos, 2014). In addition, biodiesel known chemically as monoalkyl esters of long chain fatty acids (FAME) (Singh and Taggar, 2014), also holds many other advantageous characteristics. These include reduction of most exhaust emissions compared to petrodiesel, higher cetane number, biodegradability, lack of sulfur, inherent lubricity, positive energy balance, higher flash point, compatibility with the fuel distribution infrastructure existing, renewable and domestic sources (Hajjari et al., 2014). The latter feature could not only potentially ensure a continuous, consistent and economical supply of raw materials, but could also provide opportunities for the indigenous development of especially rural and isolated regions.
