Process for the delignification of cellulosic materials |
| abstract |
Process for the delignification of cellulosic materials comprising: - a first step of treating cellulosic materials with an acid - a second step of treatment with hydrogen peroxide in an alkaline medium - a third step of cooking in the presence of a chemical reagent selected from sulfur compounds and oxygen. The method applies to the treatment of wood fragments. |
