Description

Das Anwendungsgebiet der Erfindung ist die Herstellung von weißtorfartigen Bodenverbesserungsmitteln aus lignocellu­ losehaltigen Materialien.The field of application of the invention is the production of white peat-like soil conditioners made from lignocellu loose materials.

Torf entsteht durch die natürliche Verrottung von Lignocel­ lulose. Dabei wird die Cellulose durch Mikroorganismen zu­ erst in oligo- und monomere Zucker umgewandelt, die dann von anderen Mikroorganismen in CO2 und Wasser zerlegt werden. Als Nebenprodukt dieser Umsetzung entstehen Huminsäuren. Die Biomasse dieser Mikroorganismen dient dann als Nahrung für Kleinlebewesen. So besteht der fertige Torf hauptsächlich aus Lignin und anderen schwer angreifbaren Verbindungen sowie aus Huminsäureprodukten, die ebenfalls nicht wasserlöslich sind. Die Verrottungsgeschwindigkeit ist abhängig von der Temperatur und der Feuchtigkeit. Der Prozeß dauert gewöhn­ lich viele Jahre bzw. Jahrzehnte. Die Zersetzung der Cellu­ lose führt zur Veränderung der Struktur der Stoffe. Die Festigkeit wird erheblich reduziert.Peat is created by the natural rotting of lignocel lulose. Microorganisms first convert the cellulose into oligomeric and monomeric sugars, which are then broken down into CO 2 and water by other microorganisms. Humic acids are a by-product of this reaction. The biomass of these microorganisms then serves as food for small organisms. The finished peat consists mainly of lignin and other difficult to attack compounds as well as humic acid products, which are also not water-soluble. The rate of rotting depends on the temperature and the humidity. The process usually takes many years or decades. The decomposition of the cellulose changes the structure of the fabrics. The strength is significantly reduced.

Da der Torfabbau einerseits große ökologische Schäden mit sich bringt und die Torfvorräte andererseits immer knapper werden, sucht man seit einigen Jahren nach Ersatzprodukten. Es sind sogenannte Kompostierverfahren bekannt, bei denen Baumrinde und andere pflanzliche Abfälle kompostiert werden. Dabei wird die Aktivität der Mikroorganismen durch Zugabe von Nährstoffen, wie z. B. Harnstoff, erhöht. Es sind auch Verfahren bekannt, bei denen die Stoffe zuerst thermisch oder chemothermisch vorbehandelt und dann kompostiert werden. Die Geschwindigkeit der Kompostierung ist abhängig von Tem­ peratur, Feuchtigkeit und Nährstoffmenge. Der Prozeß dauert zwischen 6 Wochen und 15 Monaten. Die Produkte haben einen hohen Biomasseanteil und sind je nach Dauer der Verrottung noch aktiv. Sie können entweder als Komposte und Humusdünger oder nach Zugabe von Torf als sogenannte Kultursubstrate ein­ gesetzt werden. Den Weißtorf mit seiner Funktion als aus­ schließlich physikalisch wirkendes Bodenverbesserungsmittel können sie nicht ersetzen. Because the peat mining has great ecological damage brings itself and the peat stocks on the other hand increasingly scarce have been looking for replacement products for several years. So-called composting processes are known in which Tree bark and other vegetable waste are composted. The activity of the microorganisms is increased of nutrients such as B. urea, increased. They are too Processes known in which the substances are first thermally or pretreated chemothermally and then composted. The speed of composting depends on the tem temperature, moisture and amount of nutrients. The process is ongoing between 6 weeks and 15 months. The products have one high proportion of biomass and depending on the duration of the rotting still active. You can use it as either compost and humus fertilizer or after adding peat as a so-called culture substrate be set. The white peat with its function as out finally, physical soil improver cannot replace them.  

Der vorliegenden Erfindung liegt deshalb folgende Aufgabe zugrunde:The present invention therefore has the following object based on:

Es soll ein Verfahren zur Herstellung von weißtorfartigen Bodenverbesserungsmitteln aus leicht verfügbaren lignocel­ lulosehaltigen Materialien angegeben werden, das leicht steuerbar ist, schnell und mit einem hohen Mechanisierungs­ grad realisiert werden kann.It is said to be a process for producing white peat-like Soil improvers made from readily available lignocel Lulose-containing materials can be specified that easily is controllable, quickly and with a high level of mechanization degree can be realized.

Diese Aufgabe wird durch ein Verfahren gemäß Anspruch 1 ge­ löst. Die Erfindung weist gegenüber den obengenannten Kom­ postierverfahren folgende Vorteile auf:This object is achieved by a method according to claim 1 solves. The invention has compared to the above Kom the following advantages:

  • 1. Durch eine definierte, partielle Hydrolyse mit anschlie­ ßender Extraktion der gelösten Bestandteile wird ein Pro­ dukt gewonnen, das nach einer Zerfaserung dem Torf in seiner chemischen Zusammensetzung und seiner Struktur so­ wie in seinen physikalischen Eigenschaften sehr ähnlich ist.1. By a defined, partial hydrolysis followed by The extraction of the dissolved components becomes a pro product won, which after a defibration into the peat in its chemical composition and structure like this as very similar in its physical properties is.
  • 2. Die extrahierten Stoffe können zu wertvollen Nebenpro­ dukten, wie Harzen, Spezialzuckern, Protein oder Äthanol aufbereitet werden, so daß die Wertschöpfung beträchtlich erhöht wird.2. The extracted substances can be valuable side pro products such as resins, special sugars, protein or ethanol be processed so that the added value is considerable is increased.
  • 3. Der Prozeß dauert insgesamt nur etwa 1 Stunde.3. The process only takes about 1 hour in total.
  • 4. Es können alle cellulosehaltigen Roh- und Reststoffe ver­ wendet werden.4. All cellulose-containing raw materials and residues can be used be applied.
AnwendungsbeispielApplication example

Laubholz soll zu einem weißtorfähnlichen Bodenverbesserungs­ mittel verarbeitet werden. Das Holz wird zuerst gehäckselt. Die Hackspäne haben ähnliche Dimensionen wie die bei der Zellstoffproduktion.Hardwood is said to be a white peat-like soil improvement be processed medium. The wood is chopped first. The chips have dimensions similar to that of the Pulp production.

Sie werden nach Zugabe einer Säure auf Temperaturen über 100°C erhitzt. Nach einer bestimmten Verweilzeit, deren Länge von der Höhe der Temperatur abhängt, werden zuerst die flüchtigen Bestandteile mit Dampf und dann die gelösten Bestandteile mit Wasser extrahiert und abgetrennt.They will heat up to temperatures after adding an acid Heated to 100 ° C. After a certain dwell time, whose Length depends on the level of temperature, first the volatile components with steam and then the dissolved Ingredients extracted with water and separated.

Nach dieser Extraktion haben die ungelösten Stoffe immer noch die Struktur der Holzspäne. Sie werden dann in einer Mühle grob zerfasert.After this extraction, the undissolved substances always have nor the structure of the wood chips. You will then be in one Mill roughly frayed.

Das Produkt ist in seiner Struktur und seiner Zusammen­ setzung dem Weißmoortorf sehr ähnlich und kann diesen als physikalisches Bodenverbesserungsmittel voll ersetzen.The product is in its structure and together setting very similar to the white moor peat and can be used as Fully replace physical soil conditioner.
