for year 2007. A new black carbon (BC) emissions inventory from China found BC emissions levels in 2007 of 1,957 Gg BC—higher than reported in earlier studies. The paper by researchers from Peking University and Environment Canada appears in the ACS journal Environmental Science & Technology. 2007 were used in this study.

Researchers at the University of Wisconsin, led by Dr. Rolf Reitz, are investigating a blended dual-fuel (gasoline and diesel) concept to extend the operating range of partially premixed charge compression ignition combustion by using the varying fuel reactivity of the charge blend, which is determined in real time.

Neste Oil has completed the first phase of its project to build a pilot plant for producing microbial oil for use as a feedstock for NExBTL renewable diesel. The technology is designed to produce feedstock for NExBTL renewable diesel by using yeast and fungi to convert sugars from waste and residues into oil highly efficiently.

NO x emissions results of biodiesel, renewable, and GTL diesel fuel blends, and CARB diesel fuel for 2006 Cummins ISM. They also found that increasing renewable diesel (Neste Oil’s NExBTL) and gas-to-liquids (GTL) diesel blends showed NO x reductions with rising blend level. Credit: ACS, Hajbabaei et al.
