This research, published in the journal Separation and Purification Technology , shows that ozone can be used to remove not only SO x but also NO x from fossil fuel combustion exhaust streams. In this study, to improve absorption performance of SO 2 and NO 2 , we added ozone in exhaust gas. Osaka et al.

The Health Effects Institute (HEI) has launched two new studies funded under RFA 21-1, Quantifying Real-World Impacts of Non-Tailpipe Particulate Matter Emissions. The new studies are: Improved Characterization of the Real-World Contributions and Impacts of Non-tailpipe Particulate Matter Emissions ,” led by Greg Evans, University of Toronto.

The California Air Resources Board (CARB) has released the results of a multiyear study evaluating exhaust emissions from the use of California Reformulated Gasoline (CaRFG) that contains 15 volume percent ethanol (E15). The study used two fuels—an E10 and E15. SULEV30, ULEV50, ULEV70, and ULEV125).

According to a study commissioned by the Washington, DC-based Propane Education & Research Council (PERC), NO x emissions measured from propane autogas school buses were substantially lower than those measured from diesel school buses. For the stop-and-go route, NO x emissions were 34 times higher for the diesel school bus.

At cruising altitude, airplanes emit a steady stream of NO x into the atmosphere, where the chemicals can linger to produce ozone and fine particulates. Now, MIT engineers are proposing using an ammonia-based selective catalytic reduction (SCR) system that could result in an approximately 95% reduction in NO x emissions in exchange for a ~0.5%

Regulatory regimes seeking to reduce emissions from transport have largely focused on tailpipe emissions—i.e., the criteria pollutants and CO 2 that emerge with the exhaust from the tailpipe. Non-exhaust PM factors include tire wear, brake wear, road surface wear and resuspension of road dust. earlier post ). Background.
