Beschreibung
Zusammenfassung:A sulphite cooking process is described for the production of pulp from materials containing lignocelluloses, with recovery of the cooking chemicals, in which the cooking, the blowing, the washing and the bleaching are performed sucessively. The waste liquor is subjected to several thermal treatments for the recovery of the cooking chemicals. For the cooking of the lignocellulosic materials, alkaline sulphite solutions are used, to which one or, in mixture, several low-boiling solvents are added, as well as at least one compound suitable as a redox catalyst.
