FIELD: process engineering.
SUBSTANCE: invention relates to removal of furfural and acetic acid from the flow containing water, C5, C6 and compound selected from acetic acid and furfural. Proposed method comprises interaction of the first flow with adsorptive medium which interacted preliminary with the second flow containing the same components. Adsorptive medium was regenerated, with no contact with the second flow, so that at least 70% of adsorbed furfural and acetic acid were desorbed and at least 60% of C5, C6 were adsorbed in the medium. Said medium represents spherical particles of activated charcoal. C5 is the sum of arabinan and xylene while C6 is glucan.
EFFECT: higher efficiency of byproduct removal.
