The term biofuel is used to define fuels that are obtainable from plants or animals. Being a renewable source, it is gaining attention all over the world today. Biofuel is defined as fuel comprising of mono-alkyl esters of long fatty acids derived from vegetable oils or animal fats. We have made fossil fuels and petroleum products an indispensable part of our lives. We use it for transportation, domestic heating, cooking among others.
The National Biofuel Policy of India was released in 2011. The goal of the Policy is to ensure that a minimum level of biofuels become readily available in the market to meet the demand at any given time. An indicative target of 20% blending of biofuels, both for bio-diesel and bio-ethanol, by 2017 is proposed.
There are many standards that has to be met and two of the important specifications are Thermal and Oxidation stability, If biofuel has to be produced in large scale storage is an important stage to be considered. But in storage of biodiesel due to oxidation fatty acid becomes rancid and sediments are formed.
Hence it is necessary to determine Thermal and Oxidation stability. The sediments formed tend to cause problems in the fuel injection systems, nozzles, burners etc. and causes fouling in injection system. One recent comparison of the methyl esters of Honge oil to the ASTM D6751 standard for biodiesel fuels shows that processed Honge oil is just within the standards. Against the European EN 14214 standards, Honge oil does not meet the storage stability standard; Oxidation stability needs to be a minimum of 6 hours at 110°C hence the oxidation stability has to be ascertained and it is the objective of our project.
