Abstract
The invention concerns a procedure for the bleaching of pulp, in which procedure an oxidating bleaching chemical containing chlorine is used. The essential feature of the invention is that the pulp is treated, either in conjuction with or before oxidation, with a lignin-modifying oxidation-reduction enzyme, such as the laccase produced by the white-rot fungus. The oxidating bleaching chemical used in the procedure may be chlorine dioxide or a mixture of chlorine dioxide and chlorine gas. The use of said enzyme reduces the amount of chlorophenols and other forms of organically bound chlorine in the bleaching effluent, simultaneously lowering its chemical oxygen demand.
Claims (10)
1 A process for bleaching pulp, comprising using an oxidizing bleaching chemical containing chlorine, wherein during or before oxidation, the pulp is enzyme treated with the phenoloxidase, laccase, produced by Trametes hirsuta white-rot fungus.
2. The process of claim 1, wherein the redox potential of the enzymatic reaction is below 400 mV.
3. The process of claim 2, wherein the redox potential is below 250 mV.
4. The process of claim 1, 2 or 3, wherein the pulp is treated with laccase and washed before a first oxidation stage.
5. The process of claim 1, 2 or 3, wherein the bleaching chemical is chlorine dioxide or a mixture thereof with chlorine gas, and between oxidation stages the pulp is treated with an alkali.
6. The process of claim 1, 2 or 3, wherein the enzyme treatment is at a temperature of 10 to 90°C and a pH of 3.0 to 10Ø
7. The process of claim 6, wherein the temperature is 40 to 80°C and the pH is 4.0 to 8Ø
8. The process of claim 1, 2, 3 or 7, wherein the pulp is softwood pulp.
9. The process of claim 8, wherein the pulp is pine sulphate pulp.
10. Use of the phenoloxidase, laccase, produced by Trametes hirsuta white-rot fungus in a pulp bleaching process using an oxidizing bleaching chemical containing chlorine.
