METHODS FOR CATALYTIC OXIDATION OF PULP AND FOR PRODUCING A PULP PRODUCT, E, PULP PRODUCT. Cellulose is catalytically oxidized using a heterocyclic nitroxyl radical as the catalyst, the main oxidant acting as the oxygen source, and a heterocyclic nitroxyl radical activator. The oxidation is carried out in a reaction medium which is of average consistency of cellulosic pulp, which is above 6%, more preferably equal to or greater than 8%, and most preferably in the range of 8 to 12%. The reaction medium is mixed in a reactor by circulating the feed medium back to the reactor. |
