| titleOfInvention | Process for the preparation of viscose cellulosic substances |
| abstract | Invention Patent: <B> "PROCESS FOR THE PREPARATION OF VISCOSE CELLULOSIC SUBSTANCES" <D>. The present invention relates to a process for the preparation of cellulosic viscose substance from lignocelluloses such as wood from leafy scrub, coniferous trees or one-year plants, in which process the lignocellulose is treated in a boiler initially with saturated steam for pre -hidrolysis of hemicelluloses and then without distension with black liquor (HSL) from a cooking of the preceding sulphate cellulosic substance, as well as possibly with the addition of fresh white liquor (WL) for the neutralization of the acid reaction products originated, so in boiler originates neutralization bleach (NL). After adding the required amount of alkali in the form of fresh white liquor (WL), possibly connected with a displacement of the neutralization liquor (NL) and temperature adjustment, cooking is carried out immediately with or without a temperature gradient. Upon reaching the desired degree of disintegration, cooking is terminated by the displacement of hot black liquor (HSL), simultaneously the cellulosic substance is released from lignin degradation products still adhering and the cellulosic substance thus obtained is evacuated at a temperature below 100 ‹C of the boiler. |
