UC Davis process produces gasoline-range hydrocarbons from biomass-derived levulinic acid; field-to-tank yield of >60% claimed

Green Car Congress

Researchers at the University of California, Davis have developed a process for the production of branched C 7 –C 10 hydrocarbons in the gasoline volatility range from biomass-derived levulinic acid with good yield, operating under relatively mild conditions, with short reaction times. barrels of oil (117.6 barrels of oil (117.6

Argonne analysis shows greenhouse gas emissions similar for shale, conventional oil

Green Car Congress

Shale oil production generates greenhouse gas emissions at levels similar to conventional crude oil production, according to a pair of new studies released by the US Department of Energy’s Argonne National Laboratory. These are shale formations with low permeability and must be hydraulically fractured to produce oil and gas.

Study finds coal trains add significant amount of PM2.5 pollution in urban areas

Green Car Congress

Coal trains and terminal operations add a significant amount of fine particulate matter (PM 2.5 ) pollution to urban areas—more so than other freight or passenger trains— according to a study conducted in Richmond, California, by the University of California, Davis. The results indicate coal trains add on average 8.32

New lifecycle analysis of WTW GHG emissions of diesel and gasoline refined in US from Canadian oil sands crude

Green Car Congress

In a new, comprehensive study, a team from Argonne National Laboratory, Stanford University and UC Davis ITS has estimated the well-to-wheels (WTW) GHG emissions of US production of gasoline and diesel sourced from Canadian oil sands. This range can be compared to ∼4.4 g CO 2 e/MJ for US conventional crude oil recovery.

UC Davis ITS researchers take a detailed look at water consumption and withdrawal requirements for ethanol

Green Car Congress

While a number of studies have tired to assess the water consumption required for ethanol production, the results differ by orders of magnitude, with estimates ranging from 1.1 BW consumption intensities of gasoline from conventional crude oil and Canadian oil sands range from 0.41 Click to enlarge. and from 0.29
