Separation and Purification of Hemicellulose by Ultrafiltration

Industrial & Engineering Chemistry Research, 2011
[EN]During hydrolysis treatments, where the main objective is the solubilization of hemicelluloses, several undesirable reactions may occur. As a result, monomeric sugars and nonsaccharide compounds are obtained in the liquor. In the present study, autohydrolysis liquor resulting from the corn waste hydrolysis treatment (180 ºC, 30 min) was filtered ...
