Preparation of biodiesel fuel from Urtica dioica seeds oil and study different Properties
AbstractRecently,biofuels are considered as an important alternative energy resource and could be a substitute for fossile fuels,due to the fact the increasing awarenees of the environmental pollution issues and depletion of fossil fuel resources (crude oil, natural gas and coal). The greatest motivation for producing biofuels is the clobal warming caused by the continuous burning of fossile fuels.
In this study,fatty acid methyl esters,known as biodiesel fuel derived from triglycerides(virgin vegetable oil of nettle),by transesterifacation with methanol,show the promising yield and better quality of biodiesel. This paper presents the development for the production of biodiesel from the vegetable oil having the high yield 91% where the transesterification reaction is promoted by finding an optimal conditions.
Clearly the process of transesterification is directly affected by the mode of reaction condition including: molar ratio of alcohol to oil, type of alcohol, amount of KOH, reaction time and temperature. In the present paper,various conditions of preparation of biodiesel have been described to obtain the best quality and high yield.
