Abstract

Fremgangsmåte ved fremstilling av bleket lignocellulose for anvendelse i masse- og papirindustrien, hvilken masse har et nedsatt totalt organisk bundet klor og nedsatt lyshetsreversering. Lignocellulosemassen under-kastes ett eller flere xylanasebehandlingstrinn i kombinasjon med ett eller flere kjemiske bleketrinn.Process for the preparation of bleached lignocellulose for use in the pulp and paper industry, which pulp has a reduced total organically bound chlorine and reduced brightness reversal. The lignocellulosic mass is subjected to one or more xylanase treatment steps in combination with one or more chemical bleaching steps.
