Biofuels:  Value-Added Chemicals and Fuels from Biomass

Dr. Halterman and his co-researchers seek to take advantage of the highly oxygenated nature of biomass-derived glucose and other carbohydrates to convert them into value-added functionalized chemical feedstocks. One current approach is to prepare shape-selective environments that would favor oxidation only at the primary carbon positions.

Additionally, new catalyst systems will be developed to dimerize cellulose-derived aldehydes into larger molecules that would be more valuable as fuels.  The resulting diols could also be further converted by the Nicholas deoxydehyration methods. 

Dr. Halterman and his colleagues are also working to optimize reformation of propanal that can be obtained from pyrolysis material or glycerol.
