Abstract:Tämä väitöskirja käsittelee IONCELL-P(ulp)-prosessia, jonka avulla jalostetaan hemiselluloosapitoisesta paperisellusta puhdasta liukosellua ja polymeeristä hemiselluloosaa. Erotetut fraktiot (selluloosa ja hemiselluloosa) voidaan kerätä ilman saantohävikkiä tai polymeerien hajoamista, jalisäksi prosessi säilyttää selluloosan luontaisen kiderakenteen. Täten prosessi tarjoaa korkeasaantoisen liukosellun tuotannon rinnalle perustan hemiselluloosa pohjaisille tuotteille. |
