UMass Amherst chemical engineers say 'mini-cellulose' molecule unlocks biofuel chemistry
Date:2/16/2012

r says. By creating reaction models of wood conversion, the scientists can design biomass reactors to optimize the specific reactions that are ideal for production of biofuels. For biofuels production, "We want to maximize our new pathway to produce furans and minimize the formation of gases such as CO2," says Dauenhauer.

The discovery of "mini-cellulose" was enabled by a new experimental technique for studying high-temperature biomass chemistry called "thin-film pyrolysis." It involves creating sheets of cellulose, which makes up 60 percent of wood biomass, that are very thin, just a few microns thick. When the sheets are very rapidly heated at over one million degrees Celsius per minute, they create volatile chemicals which are the precursors of biofuel.

Dauenhauer joined the university in 2009 and conducts his research as part of the Catalysis Center for Energy Innovation in collaboration with the University of Delaware and funded by the U.S. Department of Energy (DOE). His research team includes Professor Dion Vlachos and graduate students Matt Mettler, Alex Paulsen and Samir Mushrif.

Dauenhauer has received several high-profile grants in the past year. In May 2011, he awarded a five-year, $800,000 Early Career Award in Basic Energy Sciences from the DOE. The grant provides support for his research on understanding the catalysts that control the process of breaking down plant matter into chemicals and fuel byproducts.

In February 2011, he was awarded a one-year, $80,000 grant from the National Science Foundation to conduct basic research on pyrolysis. Additionally in 2011, he was awarded a three-year Young Faculty Award from the 3M Corporation.
