Abstract
Increasing of the heating value of combustible biomass through hemicellulose extraction and subsequent press-drying is described. After hemicellulose extraction the remaining biomass is soft and easily press-dried to high dry content of up to 80%. The method involves the removal of most water binding hemicelluloses and retaining most of the lignin in the biomass. Lignin can either be retained in the biomass during the extraction or combining the lignin, which has been separated from the hemicellulose extract, with the extracted biomass.
