Abstract

Filtrater fra bleking og delignifisering av masse resirkuleres for anvendelse ved oppslutning, separasjon og gjenvinning av lignin (66) og andre biprodukter, hvilket forer til en vesentlig energiinnsparing og unngåelse eller eventuelt eliminering av forurensing som typisk er assosiert med bleking. Oppfinnel- sen vedrører også produkter avledet fra prosessen og et apparat for utføring av prosessen. Ligniner med varierende molekylvekter og biprodukter fra oppslut- ningsprosessen blir også gjenvunnet (66). Ligninene utfelles i høye utbytter og med høy hastighet fra en svartlut (40) dannet ved oppslutning av tre ved høy temperatur og trykk. Som biprodukt ved prosessen gjenvinnes et renset furfuralprodukt (71). Dette furfural kan resirkuleres for anvendelse ved gjen- vinning av lavmolekylært lignin i foreliggende prosess.
