| Sumario: | Oil from Haematococcus pluvialis microalgae was modified via a transesterification reaction to obtain a mixture of fatty acid methyl esters (FAMEs). The mixture of FAMEs was evaluated as an environmentally friendly friction modifier and antiwear additive for diesel fuel in this study. Purification of the mixture with bentonite was used due to the content of pigment. FAME was studied as an additive at concentrations of 5%, 10%, and 20% w/w in diesel fuel, and their physicochemical and tribological (lubricity) characterization was conducted. The dieselFAME blends were found to meet standard values for viscosity, flash point, and lubricity. The FAME derived from the H. pluvialis microalgae exhibited remarkable antifriction and antiwear properties when added to diesel fuel with friction and wear reductions ranging from 40 to 50 %. The improvement of lubricity of the diesel fuel was similar for all the FAMEs concentrations used. The enhanced lubricity of the blends has been attributed to the high content of fatty acids with chain lengths of 17–18 in the oil from H. pluvialis and the formation of oxide films on the wear scar. |
