The Biodiesel is an alternative fuel which can be produced from various feedstocks like vegetable oils, seeds, animal fats and animal tallow. In-case of oil it will be extracted from the seeds with the help of an expelling process. Chemical expelling is efficient method to extract oil from the seeds when compared to mechanical expelling. Due to lower production cost mechanical expelling will be used in most of the cases. This oil consists of FFA content, Based on FFA content single step/two step transterification process will be followed. In this Linseed oil the FFA content is 1.87, hence single step transterification process is followed. The triglyceride esters will be converted into the Mono-glyceride by a catalyzed reaction. The reaction conditions generally involve a trade-off between reaction time and temperature as reaction completeness is the most critical fuel quality parameter. Much of the process complexity originates from contaminants in the feedstock, such as water and free fatty acids, or impurities in the final product, such as methanol, free glycerol, and soap. Processes have been developed to produce biodiesel from high free fatty acid feedstocks, such as recycled restaurant grease, animal fats, and soap stock. This linseed seed has been tested with FTIR analysis, GC-MS analysis and physical properties. All the properties are satisfying the ASTM standards. The physical properties of the linseed biodiesel has been incorporated. |
