METHOD FOR EXTRACTING BIOMASS

Method for extraction of biomass with water in order to separate hemicelluloses from a fibrous structure. The biomass is impregnated under reduced pressure with the extraction fluid in order to prevent the degradation of the components to be extracted. During extraction the extract is circulated thr...

Zusammenfassung:	Method for extraction of biomass with water in order to separate hemicelluloses from a fibrous structure. The biomass is impregnated under reduced pressure with the extraction fluid in order to prevent the degradation of the components to be extracted. During extraction the extract is circulated through the fiber matrix in order to remove unwanted components from the extract. The extract is reused for extracting untreated biomass in order to increase the consistency of the extract.
