Comparative Study of Extraction Methods and Properties of Non Edible Oils for Biodiesel Production

摘要

Due to the limited availability of fossil fuel and environmental problems, considerable attention has been given toudbiodiesel production as an alternative to petro diesel. In this connection the non-edible seeds of Caryota urens,udBassia longifolia and Saraca asoca were analysed for their oil properties and fatty acids. Four different methodsudare tried for oil extraction among them physical method is more suited compared to Bligh and Dyer, Folch et al.udand Chemical solvent extraction method and among the three seeds B. longifolia yields more oil (40mg/g) comparedudto S. asoca (35gm/g) and C. urens (25gm/g) and udasoca.
