Presentation Title

Assessing Alternatives: Chemical Content Analysis Of Biodiesel Vs. Diesel Fuel Emissions

Mentor

Location

David F. Putnam Science Center - 175

Abstract

With climate change an increasing concern, the push towards alternative energy sources from fossil fuels is very strong. Biodiesel fuel is one such alternative; however, it is important to consider that the combustion of biodiesel may contain toxic and harmful organic compounds that are emitted into the atmosphere. For this study, airborne particulate matter was collected on filters over a ten-day period for both diesel and biodiesel fuels at two workspace locations within the Keene Recycling Center. Collected particulate matter was categorized by size using multiple filters within an impactor device. Filters were analyzed for the presence of 61 different organic compounds using gas chromatography mass spectrometry with high sensitivity. Results will be presented that compare the differences in chemical content found in the emissions from the two fuels and examine these chemical differences with specific ranges of particulate matter size.
