Study on Effect of Peroxide Properties for Biodiesel and Emissions

doi:10.3969/j.issn.1000-1093.2012.12.023

Abstract

Abstract: Biodiesel was redesigned by peroxidation. The mechanism of peroxide modification was discussed. The viscosity and peroxide value of biodiesel before and after peroxide modifications were measured and analyzed. Experiments were carried out in a 170F engine fueled with biodiesel and peroxide biodiesel, and the impacts of peroxide modification on NOx emissions and carbon smoke were studied. The results show that the carbon double bonds of fatty acid methyl esters are broken after peroxide modification, the degree of saturation is increased, oxidation stability is improved significantly, and dynamic viscosity of biodiesel is much lower than that of biodiesel up to a maximum of 8.2%. Both NOx emission and carbon smoke decrease for the investigated operating conditions.

Key words: power machinery engineering, biodiesel, peroxide modification, oxidation stability, carbon smoke, NOx
