Study finds PM from biodiesel blends may be 50-80% less toxic per unit PM mass than from petroleum diesel

Green Car Congress

In a study published in the ACS journal Energy & Fuels , a team from the University of Vermont reports that particulate matter from the combustion of biodiesel blends may be 50–80% less toxic per unit PM mass emitted than PM from petroleum diesel, depending on feedstock. PM-normalized DTT Activity for biodiesel exhaust PM. to 13.6 ± 3.8

Jatropha Biodiesel-FT Blends Reduce Most Criteria Pollutants Compared to Neat FT; Higher NOx

Green Car Congress

Blending jatropha biodiesel (JBD) with Fischer-Tropsch synthetic diesel (FT) results in lower CO, THC, smoke and PM emissions compared to neat FT, according to a study by researchers at the Norwegian University of Science and Technology (NTNU) published in the ACS journal Energy & Fuels.

Optimizing Turbo Diesels for Emissions and Performance with 5% and 20% Biodiesel Blends

Green Car Congress

While these NO x reductions are also accompanied by reductions in both PM and noise, these settings have a limited net effect on counter-acting the lower energy density effects of biodiesel. Their study was published online 21 December in the ACS journal Energy & Fuels. However, with an energy density 13% lower than diesel (37.5
