USE OF BINARY BLENDS OF OILS FOR BIODIESEL PRODUCTION

Abstract

Rapid urbanization has led to increased consumption of dwindling fossil fuels resources which are associated with huge environmental emissions. To meet the growing energy demands, Government of India and other countries of the world are focusing on the production of oils, their conversion to biodiesels and their utilization as diesel engine fuel to generate power. Significant work is already done globally on conversion of individual oil resources, particularly, the non-edible oils to biodiesel. The literature reveals that in the light of enhancing the fuel characteristics like viscosity and cold flow properties lot of additives are used to get the desired quality fuel. Less work is available on using the binary blends of oil for biodiesel production. The dissertation work deals with selection of oils, making their blends [Jatropha curcas oil (JCO) and Eucalyptus oil (EO)] in different proportions, measuring their fuel properties and converting these blends to biodiesel under standard conditions. The fuel properties of all biodiesel blends are reported and compared with BIS standards. Blending shows notable improvement in viscosity and cold flow properties. The results showed that oil blend of 25:75(JCO:EO) and biodiesel blend of 60:40(JCO:EO) can be used directly in diesel engine without any modification.
