Salvia farinacea seed oil, a potential biomass for synthesis of biodiesel: A critical analysis of its fuel properties.

Abstract

The non-renewable energy sources such as coal, petrol decreasing day by day and their price also increasing. In this fast depleting era of fossil fuels biodiesel produced from nonedible seed oils plays an important role. In the present work the biodiesel is produced from nonedible seed oil Salvia farinacea. In this work from Salvia farinacea seeds oil is extracted and fatty acid components are analysed by GC-FID. Physicochemical properties of the oil are determined by AOAC standard methods. The oil is transesterified in presence of KOH catalyst. Fuel parameters like iodine number, cetane number, heating values, kinematic viscosity, flash point, cold flow properties are determined and are compared with already existing biodiesels and petrodiesel. The emission components like CO, CO­­2, NOx, HC and Smoke opacity are analysed using four stroke one cylinder engine. This work reveals that Salvia farinacea seed oil is a potential renewable feedstock for the production of biodiesel.
