Abstract
The Clean Fractionation process provides rapid access to all three polymeric components of lignocellulosics. However, the aqueous hemicellulose fraction has been more difficult to purify than either the lignin or cellulose fraction. Hemicellulose sugars are present along with the acid promoter and other organic acids, residual organic solvent, and low molecular weight lignin fragments. We have investigated several approaches for the purification of this fraction to give a pure stream of hemicellulose derived sugars. The paper will discuss the different purification methods employed, the effect of separation conditions on the sugar composition of the hemicellulose fraction, and characterization of the hemicellulose components present.
