Abstract

Die Erfindung betrifft ein Verfahren zur Gewinnung von Torfersatz-Fasern aus faserhaltiger Biomasse, insbesondere Jahrespflanzen, wobei die Biomasse einem hydrothermalen Aufschluss in einer Thermo-Druck-Hydrolyse, vorzugsweise mit Dampf-Explosion, unterzogen wird, und nachfolgend eine erste Separation der aufgeschlossenen Biomasse in eine erste Faserfraktion und in eine Flüssigphase, die mit gelösten organischen und anorganischen Substanzen sowie fein suspendierten Feststoffen angereichert ist, erfolgt, dadurch gekennzeichnet, dass vor dem hydrothermalen Aufschluss eine Zerkleinerung der Biomasse erfolgt, anschließend zum Anmaischen der zerkleinerten Biomasse Prozesswasser zugegeben wird, und dass nach dem hydrothermalen Aufschluss vorzugsweise in einem weiteren Schritt die aufgeschlossene Biomasse erneut angemaischt wird und danach die erste Separation erfolgt.
