University of Wisconsin-Madison and ExxonMobil extend R&D agreement two more years

In Wisconsin, the University of Wisconsin-Madison and ExxonMobil have announced a two-year renewal of an agreement to research the fundamental chemistry of converting biomass into transportation fuels. The research is part of a broad effort to identify scalable and commercially viable solutions to help meet increasing global energy demand with a renewable resource.

Over the past two years, research has focused on a multistep approach for converting cellulosic biomass to transportation fuels. A new approach with the potential to reduce the number of processing steps will be explored in this collaboration. This approach using solvents could potentially dissolve the entire biomass, which might make it possible to convert the whole biomass into fuel-sized molecules in a single reactor.

Another potential process that will be studied in this collaboration involves the catalytic transformation of bio-derived ethanol into bio-derived diesel and jet fuel. Ethanol is currently produced from a range of sources and is widely used as an additive to gasoline. This technology could potentially allow larger diesel and jet fuel molecules to be produced from renewable sources. Our research continues to focus on non-food sources like corn stover and other cellulosic feedstocks.
