Study finds lead from leaded gasoline persists in London air despite ‘90s ban

Green Car Congress

Lead levels in London’s atmosphere have dropped significantly since lead additives in gasoline were phased out, and currently meet UK air quality targets. The study, led by researchers from Imperial College London, found that up to 40% of lead in airborne particles today comes from the legacy of leaded gasoline.

UC Berkeley study quantifies LD gasoline on-road emissions

Green Car Congress

Based on on-road measurements in their study, a team from the University of California Berkeley has estimated that, as of 2010, light-duty (LD) gasoline vehicles were responsible for 85% of CO; 18% of NO x ; 18% of organic aerosol (OA); and 6% of black carbon (BC) emissions from on-road motor vehicles in the United States.

Ford researchers suggest using higher ethanol blends to boost the minimum octane number of regular-grade gasoline

Green Car Congress

Using higher volume blends of ethanol to leverage the alcohol’s inherent high octane rating to produce ethanol-gasoline blends with higher octane numbers could yield “substantial societal benefits”, according to a team of researchers from Ford Motor Company.

New Fischer-Tropsch reactor configuration to optimize gasoline production

Green Car Congress

The concept (FMFMDR) produces gasoline from synthesis gas. The simulation results of three schemes named fluidized-bed membrane dual-type reactor (FMDR), FMFMDR and conventional fixed-bed reactor (CR) are presented. Results show that the gasoline yield in FMFMDR is higher than the one in FMDR. —Rahimpour et al.

Final EPA report shows total US GHG emissions up 3.2% in 2010, total CO2 up 3.5%, total transportation CO2 up 1%

Green Car Congress

The final report shows overall emissions in 2010 increased by 3.2% EPA attributes the trend to an increase in energy consumption across all economic sectors, due to increasing energy demand associated with an expanding economy, and increased demand for electricity for air conditioning due to warmer summer weather during 2010.
