Definitions
- the present invention relates to a novel method for changing lignin-containing materials or similar substances by means of oxidation catalysts and highly effective mediators.
- Phanerochaete chrysosoporium is a very effective lignin degrader, one tried to isolate its enzymes and to use them in purified form for lignin degradation. However, this did not succeed because it turned out that the enzymes primarily lead to a repolymerization of the lignin and not to its degradation.
- Biopulping is the treatment of wood chips with living fungal systems.
- Another advantage is the mostly existing improvement in the mechanical properties of the fabric. a disadvantage the poorer final whiteness.
- Pulp mill waste water in particular bleaching effluent to decolorize and reduce the AOX (reduction of chlorinated compounds in the wastewater that cause chlorine or chlorine dioxide bleaching stages).
- the fabric is then washed over a nylon sieve (30 ⁇ m) and extracted for 1 hour at 60 ° C., 8% fabric density and 2% NaOH per g fabric.
- the fabric is then washed over a nylon sieve (30 ⁇ m) and extracted for 1 hour at 60 ° C., 8% fabric density and 2% NaOH per g fabric.
- the kappa number is determined.
- the substance is then washed over a nylon sieve (30 ⁇ m) and extracted for 1 hour at 60 ° C., 8% density and 2% NaOH per g substance.
- the kappa number is determined. A kappa number reduction from 65 to 14 was achieved.
- the fabric is then washed over a nylon sieve (30 ⁇ m) and extracted for 1 hour at 60 ° C., 8% fabric density and 2% NaOH per g fabric.
- the kappa number is determined.
- the substance is then placed in a reaction bomb preheated to 45 ° C. and incubated under 1-10 bar pressure for 1-4 hours.
- the solution is then placed in a reaction bomb preheated to 45 ° C. and incubated under 1-10 bar pressure for 1-4 hours.
- the liquefied carbon is removed from the bomb.
