Chalmers study finds ship exhaust gas scrubbers responsible for up to 9% of certain hazardous emissions into Baltic Sea

Green Car Congress

New research from Chalmers University of Technology, Sweden, finds that the discharge water from ships’ exhaust gas treatment systems—i.e., A scrubber is used on ships to clean exhaust gases, primarily to reduce emissions of sulfur oxides to the atmosphere.

Researchers use LCLS to get real-time view of chemical reaction; important insight into how catalysts work

Green Car Congress

Catalytic converters in cars, for example, reduce emissions by converting exhaust to less toxic compounds. Located in Menlo Park, California, SLAC is operated by Stanford University for the US Department of Energy Office of Science. LCLS and SSRL are supported by the DOE’s Office of Science. Resources.

Study finds automobile tires are a potential source of carcinogenic dibenzopyrenes to the environment

Green Car Congress

A new study by researchers from Stockholm University concludes that automobile tires may be a potential previously unknown source of carcinogenic dibenzopyrenes—a type of high molecular weight polycyclic aromatic hydrocarbon (PAH)—to the environment. Non-exhaust traffic sources of particles. —Sadiktsis et al.

Researchers identify ignition behavior of catalysts in catalytic converters; more efficient catalysts for cold-start conditions

Green Car Congress

Researchers from the Vienna University of Technology (Austria), Chalmers University of Technology (Sweden) and the Fritz-Haber-Institute of the Max-Planck-Society (Germany) have identified the inherent reaction behavior of different catalysts for ignition in the CO oxidation reaction in catalytic converters.
