Abstract

Det beskrives et system og en beholder for generering av polysulfid som inkluderer minst én beholder inneholdende pulpvæsken, og minst ett oksidasjonspromotorelement inkludert en oksidasjonspromotor fastsatt med overflatedekkende materiale til et substrat. Oksidasjonspromotorelementet kan fastsettes inne i beholderen eller alternativt være flyttbar mellom to eller flere beholdere for å fremme polysulfid generering og/eller gjenvinning av oksidasjonspromotoren i minst to beholdere.
