Photoacoustic spectroscopy for detection of N2O emitted from combustion of diesel/beef tallow biodiesel/sugarcane diesel and diesel/beef tallow biodiesel blends

Nitrous oxide (N 2 O) is an important greenhouse gas. Emissions of this gas are generated by the combustion of fossil fuels, mainly in the transportation sector worldwide. Biofuel is a promising alternative instead of diesel considering that it allows a reduction on the emissions of polluting gases....

Summary:Nitrous oxide (N 2 O) is an important greenhouse gas. Emissions of this gas are generated by the combustion of fossil fuels, mainly in the transportation sector worldwide. Biofuel is a promising alternative instead of diesel considering that it allows a reduction on the emissions of polluting gases. In Brazil, there is a large program on the use of biofuels, which according to the Intergovernmental Panel on Climate Change (IPCC) reduces greenhouse gas emissions. This work shows the N 2 O emissions resulting from combustions of diesel/beef tallow biodiesel blends of B7, B15, B20, B25, B35, and B50. In parallel, another experiment was done with fuel sample adopted by a bus fleet from São Paulo using blends comprising 10% of sugarcane diesel in diesel (CD10) and blends with beef tallow biodiesel of CD10: CD-B15, CD-B20, CD-B25, CD-B35, and CD-B50. The photoacoustic spectroscopy technique coupled to a quantum cascade laser (QCL) was used to detect N 2 O. Concentrations of the emissions were detected in the range of 5.3 to 7.4 ppmv for diesel/beef tallow biodiesel blends combustion and in the range of 4.3 to 11.0 ppmv for diesel/sugar cane diesel/beef tallow biodiesel blends combustion. The technique used was very sensitive and selective to identify and determine the emission concentrations of N 2 O.
