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. 517 $aInvestigation of Nitro-Organic Compounds in Diesel Engine Exhaust 606 $aBiodiesel fuels$xResearch 606 $aDiesel motor exhaust gas$xSpeciation 606 $aPolycyclic aromatic hydrocarbons$xMeasurement 606 $aOrganonitrogen compounds 606 $aSpeciation (Chemistry) 615 0$aBiodiesel fuels$xResearch. 615 0$aDiesel motor exhaust gas$xSpeciation. 615 0$aPolycyclic aromatic hydrocarbons$xMeasurement. 615 0$aOrganonitrogen compounds. 615 0$aSpeciation (Chemistry) 700 $aDane$b John$01387710 701 $aVoorhees$b Kent J$01387711 712 02$aNational Renewable Energy Laboratory (U.S.) 801 0$bSOE 801 1$bSOE 801 2$bGPO 906 $aBOOK 912 $a9910698590703321 996 $aInvestigation of nitro-organic compounds in diesel engine exhaust$93437813 997 $aUNINA
