Physicochemical Properties of Jatropha Curcas Biodiesel + Diesel Fuel No. 2 Binary Mixture atT= (288.15 to 308.15) K and Atmospheric Pressure

Abstract

Environmental issues, the growing demand for energy, political concerns, increasing crude oil prices and the medium-term depletion of petroleum created the need for the development of vegetable oils as alternative fuels. Vegetable oil-based fuels (bio fuels) are promising alternative fuels for diesel engines because of their environmental and strategic advantages. To design equipment for biofuel production and an optimizing process for biodiesel production, their thermophysical properties must be known. In this work, the Jatropha curcas biodiesel was prepared, and thermophysical properties, densities (ρ12), and speed of sound (u 12) for J. curcas biodiesel (1) + diesel fuel no. 2 (2) binary mixtures were measured as functions of composition at temperatures ranging from T = (288.15 to 308.15) K and atmospheric pressure. The observed data have been utilized to evaluate the excess molar volume, V 12 E, of this binary mixture. This binary mixture (blend) exhibits a temperature-dependent behavior, and densities decrease linearly with temperature.

Speed of sound in pure fatty acid methyl esters and biodiesel fuels

“…Unlike petrodiesel, biodiesel is a renewable fuel offering important benefits including reduction of green-house emissions, biodegradability, and non-toxicity. Biodiesel shows total miscibility with petrodiesel and compatibility with modern engines [1,2]. Nowadays, biodiesel production has important economic and social impacts at the regional development level especially to developing countries [3].…”

Biofuel Pure Component Spray Characteristics at Engine-Relevant Conditions

“…In the present study, methyl oleate is chosen as the representative pure component for rapeseed, karanja, jatropha, and soybean biodiesel. Methyl oleate is chosen, as its properties such as liquid density and normal boiling point (816 kg/m 3 ; 617 K) are found to be comparable to that of the biodiesels it represents. ,− Simillarly, methyl palmitate is selected as the representative for palm biodiesel based on its physical properties and degree of saturation . The sprays from all of these pure component FAMEs and FAEEs are studied to understand their individual contribution in the spray and the mixing process.…”

Speed of Sound in Methyl Caprate, Methyl Laurate, and Methyl Myristate: Measurement by Brillouin Light Scattering and Prediction by Wada’s Group Contribution Method

“…Biodiesel as a renewable fuel has offered some significant benefits, such as reduction of greenhouse emissions, biodegradability, and nontoxicity. Tests showed that biodiesels also have total miscibility with petrodiesel and compatibility with modern engines. , …”

“…Tests showed that biodiesels also have total miscibility with petrodiesel and compatibility with modern engines. 2,3 Biodiesels can be directly applied in existing diesel engines without modifications. However, thermophysical properties of bio-and petroleum-based diesels, such as the speed of sound, density, surface tension, and compressibility, are different as a result of the differences in the chemical structure.…”
