Definitions
- the invention relates to a method and a plant for the removal and / or conversion of lignin from lignooellulose-containing material.
- the lingocellulose-containing material such as wood or annual plants, must be freed from the lignin, since this considerably improves the mechanical and physicochemical properties of the paper made from the cellulose.
- Conventional processes work with high pressures and temperatures using environmentally harmful chemicals.
- German Patent 3110117 discloses a process for the production of cellulose from wood or other plant fiber materials, in which the lignocellulose is produced using
- the object of the present invention is to provide a method and a plant for removing and / or converting lignin from lignocellulose-containing material, in which the disadvantages of the use of microorganisms, enzymes and chemicals shown above are avoided.
- This object is achieved in that a redox potential in the range of 200-500 mV is set by adding one or more oxidizing and / or reducing agents and / or salts and / or phenolic compounds to an acidic aqueous solution of the lignin-containing raw materials, then by adding enzymes, microorganisms, animal or plant cells started a lignin-degrading reaction with simultaneous bleaching, the reaction in a value oscillating around a constant redox potential value, constant temperature, constant pH value and with constant stirring for several hours.
- the redox potential is preferably 250 to 350 mV.
- it can be determined by means of a redox electrode and kept constant by means of a regulator and an actuator during the entire reaction time by adding oxidizing and / or reducing agents and / or salts and / or phenolic compounds and / or organic acids.
- Hydrogen peroxide, oxygen and ozone are preferably used as the oxidizing agent.
- Ascorbic acid, dithionite and sodium bisulfite are suitable as reducing agents.
- MnSO 4 and / or FeCl 2 is preferably suitable as the salt.
- Veratryl alcohol can be used as the phenolic compound. Lactic acid, for example, is suitable as the organic acid.
- Lignolytic enzymes are preferably used as enzymes in the method according to the invention. These preferably include phenol oxidases, lallases and peroxidases.
- the effectiveness of the method according to the invention can be increased by adding pectinases and / or hemicellulases.
- those enzymes can be used which are obtained from the white rot fungus Phanerochaete chrysosporium. If necessary, Phanerochaete chrysosporium itself can also be added for the degradation process.
- the pH in the process according to the invention is between 2 and 5. A pH of 3 is particularly preferred.
- the temperature is 20 to 60 ° C.
- the reaction is preferably carried out at 40 ° C. If the stated conditions of the process according to the invention are observed, a redox potential of 250-350 mV can be set! As a result, the lignin content of wheat straw (approx. 18% lignin content) can be reduced to almost 0%. Spruce wood (about 28-30% lignin content) can be broken down to similar end values. Surprisingly, these results can be achieved in 2 to 6 hours, in many cases even within 2 hours. This does not include the physical and / or chemical pretreatment that is particularly necessary when using wood or annual plants.
- the redox potential is set by the ratio of the various substances added in the reaction vessel.
- Addition of the oxidizing and reducing agents, the salts and the phenolic compounds can maintain a certain redox potential throughout the course of the reaction.
- the aim of operating the redox system set in this way is to prevent repolymerization of the lignin.
- the process also has a significant bleaching effect during the degradation and / or conversion reaction, which allows it to be done with significantly less pollution Bleach to work.
- the method according to the invention is therefore also suitable as a bleaching or post-bending method for various processes.
- the process can therefore also be used for the biological bleaching and biological wastewater treatment of pulp industry wastewater and other wastewater.
- the method can be used wherever decolorization and detoxification of waste water is to be achieved.
- Another advantage of the process according to the invention is the possibility of continuous process control.
- the process can be carried out particularly economically if the used enzymes are reprocessed and returned to the reaction process. This goal can be achieved with the help of affinity chromatography.
- the enzyme is passed over a separation column, purified there and returned to the reaction process.
- the enzyme purification is carried out in the separation column by means of affinity chromatography.
- new specific types of ligands have been developed, which are used together with the corresponding enzyme technology know-how.
- ligands are described in patent application PCT / EP 87/00214.
- phenolic compounds can be used here.
- Protein-specific ligands are also suitable. Tannin is an example.
- the method also relates to a plant for removing and / or converting lignin or its
- Degradation products made from lignocellulose-containing material This consists of a reactor, a device for adding microorganisms or enzymes, a device for adding oxidizing agents, reducing agents, salts or phenolic compounds, a drain for the converted raw material, used oxidizing agents, reducing agents, Salts, phenolic compounds, enzymes and microorganisms, a device for the separation of dissolved and undissolved substances, a column for affinity chromatography, in which enzymes are reprocessed for the lignin degradation reaction and a reflux for the return of the reprocessed enzymes to the reactor. Filters or thickeners, for example, can be used as the device for separating dissolved and undissolved substances.
- Microorganisms or enzymes are added to the reactor via the inflow 7.
- the microorganisms or enzymes can optionally also be immobilized in the reactor.
- Conventional fillers and carriers can be used for the immobilization.
- Oxidizing agents, reducing agents, salts or phenolic compounds can be metered in via the inflow 4.
- the dosage can be controlled depending on the respective redox potential.
- a redox electrode must be attached to the reactor (not shown in the picture), by means of which the redox potential is continuously determined. By connecting to an appropriate control system, the redox potential can then be kept constant during the entire course of the reaction.
- the raw materials are also added via the feed line 7.
- Lignin and waste water containing lignin can also be treated in the plant according to the invention.
- the lignin is broken down in the reactor with the aid of lignolytic enzymes or microorganisms. Enzymes which come from the fungus Phanerochaete chrysosporium are particularly suitable. Microorganisms are particularly suitable as cell-free and hemicellulase-free mutants. In particular, mutants of Phenerochaeta Chrysosporium can be used.
- the converted raw material flows out of the reactor via the drain 8 together with the used chemicals, microorganisms or enzymes.
- the mixture of substances is passed, for example, through a filter 3, where .solved and undissolved substances are separated from one another.
- the enzyme-containing solution is passed through a chromatography column 2. This column works on the principle of affinity chromatography. Here the enzymes are reprocessed and then fed back to the reaction process via line 5.
- the substances separated from the enzymes are discharged via line 6.
- Special enzyme-specific ligands are used for affinity chromatography, especially phenolic compounds! Protein-specific ligands, in particular tannin, can also be used.
