Abstract
Foreliggende oppfinnelse vedrører en fremgangsmåte for fremstilling av hydrogenperoksyd, fortrinnsvis påtenkt for anvendelse ved bleking av masse, ved hvilken hydrogengass nødvendig for fremstilling av hydrogenperoksydet genereres helt eller delvis ved forgassing eller partiell forbrenning av cellulose- avluter.
