Nanoparticles increase biofuel performance

College Park, Md. (April 8, 2011) -- How to put more bang in your biofuels? Nanoparticles! A new study in the Journal of Renewable and Sustainable Energy shows that the addition of alumina nanoparticles can improve the performance and combustion of biodiesel, while producing fewer emissions.

Why add nanoparticles? The idea, says lead author R. B. Anand, an associate professor of mechanical engineering at the National Institute of Technology in Tiruchirappalli, India, is that because of their high surface-to-volume ratio, the nanoparticleswhich, in the study, had an average diameter of 51 billionths of a meterhave more reactive surfaces, allowing them to act as more efficient chemical catalysts, thus increasing fuel combustion. The presence of the particles also increases fuelair mixing in the fuel, which leads to more complete burning.

In the study, Anand and co-author J. Sadhik Basha first used a mechanical agitator to create an emulsion consisting of jatropha biodiesel (a fuel derived from the crushed seeds of the jatropha plant), water, and a surfactant, then blended in different proportions of alumina nanoparticles. In addition to outperforming regular biofuel, the nanoparticle-spiked fuels produced significantly lower quantities of nitrogen oxide and carbon monoxide gases, and created less smoke.

The researchers are now testing other types of nanoparticles, including hollow carbon nanotubes, and investigating the effects of nano-additives to engine lubrication and cooling systems. One obstacle to the application of this kind of nanotechnology is the high cost of nanoparticle production, says Anandwho also cautions that nanoparticles "should be used judiciously," because they tend to "entrain into human bodies."
