Understanding the Limitations of Removal of Hemicelluloses during Autohydrolysis of a Mixture of Southern Hardwoods

  author={Mehmet Sefik Tunc and Martin Lawoko and Adriaan R. P. van Heiningen},
Extraction of hemicelluloses from wood prior to pulping is being pursued to generate more value-added products, while still producing high quality pulp from the pre-extracted wood. For a better understanding of the factors limiting selective extraction, enzymatic hydrolysis in combination with size exclusion chromatography (SEC) was applied to milled wood and hydrothermally treated wood. Complete dissolution was achieved in a lithium chloride/dimethylacetamide solvent system after mild… CONTINUE READING
