Abstract

Foreliggende oppfinnelse omhandler en fremgangsmåte for fremstilling av en høyutbyttemasse som omfatter å a) behandle et lignocelluloseholdig materiale kjemisk ved hjelp av et oksiderende system som omfatter minst ett ikke-enzymatisk oksidasjonsmiddel hovedsakelig uten ozon og klordioksid og en aktivator ved en pH fra omkring 2 til omkring 6,5; og b) behandle det lignocelluloseholdige materialet mekanisk i en tidsperiode tilstrekkelig til å fremstille en høyutbyttemasse, hvori det lignocelluloseholdige materiale blir kjemisk behandlet før og/eller i løpet av ethvert mekanisk behandlingstrinn, og hvori det lignocelluloseholdige materiale ikke behandles kjemisk ved en pH fra omkring 11,5 til omkring 14 mellom trinnene a) og b). 23
