Abstract

Et faststoffinneholdende materiale, innbefattende organisk materiale og uorganisk partikkelformig ; materiale, inneholdt i eller produsert fra avfalls- papir eller avløp fra et anlegg for behandling av papir eller papiravfall, behandles ved å underkaste det faststoffinneholdende materiale en varmebehand- ling som forbrenner det tilstedeværende organiske materiale og danner et kalsinert produkt fra det tilstedeværende uorganiske partikkelformige ; materiale. Det erholdte kalsinerte partikkelformige materiale omdannes til en vandig suspensjon inne- holdende en saltdannende, kationisk bestanddel, og en ; reaktant som inneholder eller genererer en saltdan- i nende, anionisk bestanddel, tilsettes suspensjonen ; for å danne en uoppløselig saltutfelling. i j Det behandlede faststoffinneholdende materiale kan innbefatte kalsiumkarbonat, og hvor eventuelt dannet kalsiumoksid omdannes til kalsiumhydroksid når det kalsinerte produkt omdannes til en vandig suspensjon, den saltdannende, kationiske bestanddel omfattende kalsiumioner avledet fra kalsiumhydroksidet felles som kalsiumkarbonat ved tilsetning av karbondioksid. Temperaturen ved varmebehandlingen kan kontrolleres til å bibeholdes innen området 600-750 °C, slik at ikke mer enn 25 vekt% av tilstedeværende kalsium- karbonat spaltes til kalsiumoksid under varmebehand- lingen.
