VoorheesGolden, CO :National Renewable Energy Laboratory,[2010]1 online resource (iv, 48 pages) digital, PDF fileTitle from title screen (viewed June 29, 2010)."June 2010."Includes bibliographical references (page 48).The National Renewable Energy Laboratory upgraded its ReFUEL engine and vehicle testing facility to speciate unregulated gas-phase emissions. To complement this capability, the laboratory contracted with the Colorado School of Mines (CSM) to study the effects of soy biodiesel fuel and a diesel particle filter (DPF) on emissions of polycyclic aromatic hydrocarbons (PAH) and nitro-polycyclic aromatic hydrocarbons (NPAH). CSM developed procedures to sample diesel particulate matter (PM) emissions from raw and diluted exhaust, with and without a DPF. They also developed improved procedures for extracting PAH and NPAH from the PM and quantifying them with a gas chromatograph-electron monochromator mass spectrometer. The study found the DPF generally reduced PAH emissions by 1 to 3 orders of magnitude. PAH conversion was lowest for B100, suggesting that PAHs were forming in the DPF. Orders of magnitude reductions were also found for NPAH emissions exiting the DPF.Investigation of Nitro-Organic Compounds in Diesel Engine Exhaust Biodiesel fuelsResearchDiesel motor exhaust gasSpeciationPolycyclic aromatic hydrocarbonsMeasurementOrganonitrogen compoundsSpeciation (Chemistry)Biodiesel fuelsResearch.Diesel motor exhaust gasSpeciation.Polycyclic aromatic hydrocarbonsMeasurement.Organonitrogen compounds.Speciation (Chemistry)Dane John1387710Voorhees Kent J1387711National Renewable Energy Laboratory (U.S.)SOESOEGPOBOOK9910698590703321Investigation of nitro-organic compounds in diesel engine exhaust3437813UNINA
