A Workshop on Basic Research Needs for Clean and Efficient Combustion of Alternative Fuels*
Chemical Sciences, Geosciences, and Biosciences Division
February 16, 2006
Workshop motivation & background
Fuels other than those produced by refining light, sweet crude oil. Alternative fuels include those derived from renewable resources, such as biodiesel or ethanol, and fuels obtained via Fischer-Tropsch chemistry applied to heavy crude, shale oil, tar sands, and coal.
Tentative workshop details
The strong BES program in gas-phase chemistry, combustion diagnostics, and combustion simulation.
Co-chairs from the Sandia Combustion Research Facility (Andy McIlroy) and from academia in area of combustion/engine research.
Breakout sessions TBD – associated with technology challenges with science crosscuts?
Participants (~75) from national labs & academia, spanning range of fundamental chemistry and applied combustion/engine research
Timing and location: Fall 2006 (October) in DC area
Initial positive response from program manager (Ed Wall) and chief scientist (Jim Eberhardt)
Enols are alchohols with an adjacent double bond
Postulated in 1880 by Erlenmeyer
Seen by NMR in 1973 and in gas phase in 1976
Enols not currently in flame chemistry models
Work by team of BES-funded researchers on the Chemical Dynamics Beamline at the ALS (BL 9.0.2) using molecular beam flame sampling with tunable VUV photoionization reveals the presence of enols in many flames
New chemistry needed to explain role of enols
Shirley Award for most outstanding paper from ALS in 2005
New Experimental Tools Reveal New Class of Flame Intermediates
Advanced Light Source
New simulation tools for turbulent combustion
Molecular mixing in a planar jet flame
Laser diagnostics applied to real diesel engines
