effects of biodiesel contamination
on conventional and renewable marine diesels, i.e., NATO F-76 and
HRD-76. The physical properties and chemical composition of F-76,
HRD-76, and biodiesel were measured, including viscosity, density,
peroxide value, heat of combustion, and acid number. Long-term (ASTM
D4625) and accelerated (ASTM D5304) test methods were used to investigate
the influence of biodiesel contamination on storage stability of HRD-76,
F-76, and their blends. The impact of biodiesel contamination on oxidation
stability of neat and blended fuels was also studied by conducting
test ASTM D2274. In addition, the influence of biodiesel contamination
on physicochemical properties after stressing the fuel was investigated
according to the ASTM methods. The presence of biodiesel at contaminant
levels did not have significant effects on the fuel properties or
storage and oxidation stability of neat and blended HRD-76 or F-76.
Properties of contaminated samples were determined to meet MIL-DTL-16884N
specifications. The storage stability of the HRD-76/B100 blends was
also investigated on the basis of the ASTM D5304 method.
