Characterization and Evaluation of Fuel Properties of Pupae Biodiesel-Diesel Blends

Abstract-Biodiesel, an alternative diesel fuel derived from vegetable oil, animal fat, or waste vegetable oil (WVO). In this studies animal fat (dead pupae) can be used an alternative fuels for CI engines. The present study was therefore designed to convert the oil in the waste pupae to methyl ester and to evaluate its potential as biodiesel. In this view the properties measurement of biofuels and its blends with diesel were carried. Biofuel selected for the properties measurement is pupae oil. It is added in proportions with pure diesel so as to biodiesel form. The blends of the biodiesel are formed in volume proportions of 10, 15, 17, 20, 23, 25, 30, 40, 50, 60, 70, 80, 90 and 100 % with commercial diesel. The various physical and the chemical properties of these biodiesel and its blends with diesel were measured. From the measured properties of biodiesel were plotted on volume ratio. Also comparative studies of these properties of the blends are discussed in terms of its suitability as fuel in the CI engine. The main objective of this study is to find the suitability of these biodiesel and its blends as alternative fuel for CI Engine.

INTRODUCTION

Biodiesel through alternative is not viable because of its high cost. High price of biodiesel mainly due to extensive use of high valued refined vegetable oils for biodiesel manufacturing. To reduce its cost, a wide variety of vegetable oils which are available large excess have been reported. This has resulted in the wide variation in fuel properties of biodiesels produced. As a result each country has specified their own norms for biodiesel trading so as to suit and protect interests of local crops of those regions. Vegetable oil is good source for the production of biodiesel but with the limitation of food resource. It is necessary to look for the other sources such as animal fats. This is majorly found in butcher shops as waste. One of major source is found in silk reeling industry such as waste pupae. It is goof source of fats and lipids .In India, about 1800MT of Pupae is produce from that it can produced 200MT of Pupae oil and about 150MT of Biodiesel per annum it can fill full the requirement of fossil fuel.
