Tailpipe Particulate Matter Organic Composition from Oxidized Recycled Oil Biodiesel

Tailpipe Particulate Matter Organic Composition from Oxidized Recycled Oil Biodiesel

Given that today’s real-world fuel supply is comprised of biodiesel as a blendstock with petrodiesel, understanding how addition of biodiesel affects exhaust particle properties is critically important. This graduate research assistantship will support research quantifying the organic chemical composition of exhaust particles previously generated in emissions testing of biodiesel fuel in various states of accelerated oxidation. Project work is focused on quantifying the more polar chemical speciation of exhaust ultrafine and nanoparticles that are associated with adverse air quality and health effects. Biodiesel exhaust particle composition will be compared to control studies conducted similarly, but with petrodiesel fuel.
