Physicochemical Analysis of Camelina Sativa Seed Oil and its Transesterification to Study Fame Profiling
Due to the exponentially increasing demand, limited sources and environmental concern about fossil fuel Governments as well as researchers and industries are looking for renewable energy sources. Among these sources biodiesel is gaining lots of attention because of its environment friendly nature and comparatively non toxic exhaust products. In Developing Countries, non edible oils are permissible to use for this purpose, where seed oil is converted to biodiesel via chemical reaction. Camelina oil being non edible can be used for biodiesel production. In this study, our main concern is to evaluate oil percentage by solvent extraction and physiochemical analysis such as Acid Value, FFA, density, RI, etc. Besides this, fatty acid composition of the Camelina oil was studied using GC MS. Seed harvested from DIBER, HQ, Haldwani was used for this purpose. Transesterification was carried out using alkali catalyst to transform oil into biodiesel. Oil percentage was estimated using Soxhlet apparatus and various non polar solvents. Hexane gave the best result around 36 % with clear appearance of oil. Acid value of the oil was 5.68 mg KOH/g and after transformation it was reduced to 0.18 mg KOH/g. The conversion of oil into biodiesel was confirmed by TLC. Density of oil and biodiesel were 0.9275 g/cc and 0.872 g/cc which are within the specified limit of IS 15607:2005. Refractive index of oil and biodiesel were found 1.4771 and 1.4600 respectively. Further to this, the GC-MS study revealed that major FAME (fatty acid methyl ester) in Camelina biodiesel are linoleic acid (C18:2) 32.36%, Elaidic acid (C19:1) 19.26 %, Eicosenoic acid (C21:1) 16.78, Palmitic acid (C17:0) and rest of other fatty acids. Study results shows that camelina oil can be a good biofuel feedstock for the future prospect.
