DESY study finds edges and corners increase efficiency of catalytic converters

Green Car Congress

Catalytic converters for cleaning exhaust emissions are more efficient when they use nanoparticles with many edges, according to a study carried out at the the Deutsches Elektronen-Synchrotron (DESY), a research center of the Helmholtz Association, X-ray source PETRA III.

Study finds “markedly” high levels of diesel exhaust present in commuter trains powered by locomotives in pull-mode

Green Car Congress

Diesel-powered commuter trains may expose their passengers to elevated levels of certain black carbon and ultrafine particles, especially in the coach directly behind the locomotive, according to a new study from researchers at the University of Toronto. A paper on the study is published in the journal Atmospheric Environment. 2017.02.015.

Environment Canada/MECA team assesses black carbon emissions in GDI engine exhaust; evaluation of prototype gasoline particulate filter

Green Car Congress

Black carbon has a negative impact on the environment and on human health. They also presented the performance of a prototype GPF on removing BC particles from a selected GDI vehicle at various conditions. Their paper appears in the ACS journal Environmental Science & Technology. Credit: ACS, Chan et al. Click to enlarge.

ICCT study finds hydrotreating an inexpensive approach to remove naphthalenes from petroleum jet fuel for contrail abatement

Green Car Congress

Aircraft consume fuels and emit a range of emissions, including carbon dioxide and water vapor in the form of condensation trails (contrails). soot) present in the engine exhaust. The ice crystals in condensation trails form by the condensation of water vapor on small particulate matter (e.g.,

Altalto waste-to-jet fuel plant advances in UK; BA, Shell, Velocys

Green Car Congress

The proposed plant would take more than 500,000 tonnes each year of non-recyclable everyday household and commercial solid waste destined for landfill or incineration such as meal packaging, diapers and takeaway coffee cups and convert it into more than 60 million liters (15.85

Study suggests that decarbonizing US transport sector by converting waste CO2 to fuels would require economical air-capture of CO2

Green Car Congress

Kreutz used two examples of CCTF systems in his analysis: biodiesel from microalgae and Sandia National Laboratory’s S2P process (an effort to utilize concentrated solar energy to convert waste CO 2 into synthetic fuels, earlier post ). 90%) or to “repower” using lower carbon feedstocks or generation technologies (e.g.

Clemson research developing integrated modeling and control systems to reduce particulates from GDI engines

Green Car Congress

GDI engines have better fuel economy and lower carbon-dioxide emissions than more conventional port fuel injection engines; however, the technology results in higher fine-particle emissions. Onori will present aspects of her work on emissions controls at the upcoming 2017 American Control Conference in Seattle in May.
