Abstract

The growth in environment pollution as a result of fossil fuels increased consumption has led scientists to focus on biofuels such as biodiesel and bioalcohols. The ternary blends of bioalcohols with fossil fuels and biodiesel show better properties as fuels for diesel engine, than binary blends of biodiesel with diesel fuel. The purpose of this work is to report experimental density data for biodiesel+diesel fuel+isopropanol pseudo-ternary system at atmospheric pressure, covering the whole composition range and for temperature ranging from 293.15 to 323.15K. Based on experimental data, the accuracy of different mixing rules and empirical equations used to calculate the density of the pseudo-ternary system has been evaluated.

Highlights

  • The growth in environment pollution as a result of fossil fuels increased consumption has led scientists to focus on biofuels such as biodiesel and bioalcohols

  • Experimental data of density of biodiesel+diesel fuel+isopropanol pseudo-ternary system are shown in table 3 at temperatures between 293.15 and 323.15 K

  • It can be observed that the smallest density correspond to ternary blends with the greatest alcohol content, while the greater density correspond to ternary blends with the greater biodiesel content

Summary

Introduction

The growth in environment pollution as a result of fossil fuels increased consumption has led scientists to focus on biofuels such as biodiesel and bioalcohols. In order to solve such problems, the use of alcohols with higher carbon chain, which have better fuel properties such as higher cetane number, higher calorific value and lower latent heat of evaporation has been proposed [7, 8]. Such alcohols can be blended with both diesel fuel and biodiesel at any ratios with no phase separation [8,9,10]. More investigations on the physicochemical properties of the biodiesel+diesel fuel+isopropanol ternary system are needed as a result of the lack of data in literature
