NSF Awards $40M in 20 Grants for Research on Natural Systems, Including 8 Projects for Obtaining Hydrocarbons from Plants and Microorganisms

Green Car Congress

The project “Maximizing Conversion of Biomass Carbon to Liquid Fuel” (0938033) will be led by Rakesh Agrawal, with colleagues Mahdi Abu-Omar, Nicholas C. Ribeiro, all from Purdue University. Fundamental discoveries from this project will uncover links between the physical and chemical structure of biomass to the conversion process.

Researchers identify new pathways in low-temp oxidation of hydrocarbons; important to fuel combustion, atmospheric chemistry and biochemistry

Green Car Congress

Researchers at MIT, with colleagues at the University of Minnesota, have provided evidence and theoretical rate coefficients for new pathways in the low-temperature oxidation of hydrocarbons. The new pathways lead to the conversion of KHPs [?-ketohydroperoxides] Credit: ACS, Jalan et al. Click to enlarge. Amrit Jalan, Ionut M.

Study finds that environmental impact of corn-ethanol E85 is 23% to 33% higher than that of gasoline; environmental problem-shifting

Green Car Congress

This full analysis considered feedstock production, shipment of the feedstock to the refinery, refining/conversion, shipment of the fuel to the refueling station, and vehicle operation. For gasoline, the study reflects the US context in which crude oil is to a large extent imported and refined domestically.
