Abstract

Procédé et dispositif pour fabriquer des matières chimiques de base à partir de matériaux contenant de la cellulose. Après un traitement physique, de matériaux de départ, ceux-ci sont traités à l'ozone sans traitement chimique préalable. Le dispositif comporte deux récipients et un générateur d'ozone. La suspension à traiter passe dans le premier récipient de réaction, puis dans le second. L'ozone passe d'abord du second récipient de réaction, puis dans le premier. Applications : à la production de matières chimiques par dégradation de produits contenant de la cellulose.Method and apparatus for making basic chemical materials from materials containing cellulose. After a physical treatment of starting materials, they are treated with ozone without prior chemical treatment. The device has two containers and an ozone generator. The suspension to be treated passes into the first reaction vessel, then into the second. Ozone passes first from the second reaction vessel, then into the first. Applications: in the production of chemical materials by degradation of products containing cellulose.
