Abstract

A process is described for the biological production of cellulose on mobile vehicles, mainly ships. As can already be seen from the main application P 3110117.8, this biological process is based on the use of white rot fungi (Pleurotus ostreatus) and extracellular enzymes. The cultures required for breeding the white rot fungi and for producing the enzymes are also accommodated on the ship. The necessity for providing arrangements for the protection of the environment ceases to apply since the process does not entail pollution of the environment. The heat required for the microbiological degradation is obtained from the waste steam (exhaust steam) of the ship's turbine or from the waste heat of the cooling water of the diesel or gas engines of the driving motors.

Description

Herstellung von Zellstoff aus Holz oder anderen-ligno-Production of pulp from wood or other ligno-

cellulosehaltigen Po lanzen durch mikrobiologischen Abbau der Lignocellulose auf mobilen Fahrzeugen Die Erfindung betrifft eine biologische Zellstofferzeugung auf mobilen Fahrzeugen, insbesondere auf Wasserfahrzeugen.cellulose-containing plants through microbiological degradation of lignocellulose on mobile vehicles The invention relates to biological pulp production on mobile vehicles, in particular on watercraft.

Damit soll die Möglichkeit geschaffen werden, kleinere und saisonal auffallende Lignocellulosen wirtschaftlich und umweltfreundlich zu verarbeiten.This is to create the possibility of smaller and seasonal to process conspicuous lignocelluloses in an economical and environmentally friendly way.

Zellstoff wird aus Faserpflanzen wie Holz, Stroharten, Schilf, Bagasse etc. gewonnen, wobei die Rohstoffe zu einem mit entsprechenden Vorrichtungen ausgestatteten Werk gebracht werden.Pulp is made from fiber plants such as wood, straw, reeds and bagasse etc. won, with the raw materials to a equipped with appropriate devices Work to be brought.

Je höher die Tagesleistung des betreffenden Werkes ist, umso größer wird der Transportweg des Rohstoffes. Damit steigen mit der Tagesleistung des Zellstoffwerkes die Entfernungen der Transportwege, durch die Transportkosten für den Rohstoff oft weit über dessen Einkaufswert.The higher the daily output of the plant in question, the greater becomes the transport route of the raw material. This increases with the daily output of the pulp mill the distances of the transport routes, often due to the transport costs for the raw material far above its purchase value.

Eine Lösung dieses Problems wäre die Errichtung einer Vielzahl von kleinen Zellstoffwerken. Dem steht jedoch entgegen, daß erst ab einer bestimmten Tagesleistung Zellstoffwerke wirtschaftlich betrieben werden können. -In der Patentanmeldung P 3110 117.8 ist eingehend ein mikrobiologisches Verfahren beschrieben, nach dem mit. Hilfe eines Weißfäulepilzes und extracellulären Enzymen in verhältnismäßig kleinen Anlagen wirtschaftlich Voll- und Halbzellstoffe erzeugt werden können.One solution to this problem would be to build a variety of small pulp mills. However, this is opposed by the fact that only from a certain point onwards Daily output of pulp mills can be operated economically. -In the patent application P 3110 117.8 describes in detail a microbiological process according to which with. A white rot fungus and extracellular enzymes help in proportion small plants can economically produce full and semi-pulp.

Gegenüber den bekannten chemischen Verfahren (Sulfit-oder Sulfatverfahren) hat das in P 3110 117.8 beschriebene mikrobiologische Verfahren folgende Vorteile: 1. geringer Energieverbrauch, 2. geringere Mindestkapazität (Tagesleistung) für eine rentable Anlage, und damit niedere Investitionen, 3. umweltfreundliche Arbeitsweise, d.h. keine schädlichen Abwässer oder Abgase und keine Ablaugeprobleme. Compared to the known chemical processes (sulphite or sulphate process) the microbiological process described in P 3110 117.8 has the following advantages: 1. low energy consumption, 2. lower minimum capacity (daily output) for a profitable plant, and thus low investments, 3. environmentally friendly working method, i.e. no harmful waste water or exhaust gases and no leaching problems.

Somit ist das in der Hauptanmeldung P 3110 117.8 beschriebene Verfahren geradezu prädestiniert auf mobilen Fahrzeugen, insbesonders auf Wasserfahrzeugen, installiert zu werden. Nun ist zwar aus den DOS 2620 574 und 2720 638 ein Wasserfahrzeug bekannt geworden, auf dem Zellstoff nach den bekannten chemischen Verfahren erzeugt wird. Solche Anlagen zur Erzeugung von Zellstoff umfassen zwangsläufig den gesamten Umfang einer kompletten Zellstoff-Fabrik, wie Maschinen zum Zerkleinern, Dämpfen, Entlüften, Kochen, Zerfasern und Entwässern des Rohstoffes, gegebenenfalls auch einer Einrichtung zum Bleichen, Trocknen, zum Pressen und aus Einrichtungen zum Eindicken und Vergasen der Ablaugen und Einrichtungen für die Chemikalienrückgewinnung. Thus, the method described in the parent application P 3110 is 117.8 downright predestined on mobile vehicles, especially on watercraft, to be installed. Now the DOS 2620 574 and 2720 638 is a watercraft has become known, produced on the pulp according to the known chemical processes will. Such plants for the production of pulp inevitably encompass the whole Scope of a complete pulp factory, such as machines for shredding, steaming, Venting, boiling, shredding and dewatering of the raw material, if necessary also a device for bleaching, drying, pressing and devices for Thickening and gasifying the waste liquors and equipment for chemical recovery.

Der rentable Betrieb solch hochgezüchtetjer chemo-technischen Fabriken ist nur ab einer bestimmten Tageskapazität möglich. Kleine Anlagen können also nicht gebaut werden. The profitable operation of such highly developed chemical-technical factories is only possible from a certain daily capacity. So small systems cannot be built.

Ein weiterer Nachteil solcher Zellstoffwerke besteht in ihrem relativ hohen Frischwasserbedarf, für das eine aufwendige Wasseraufbereitung erforderlich ist. Weiterhin werden Einrichtungen für die Ablaugenaufbereitung und für die Reinigung der Abwässer benötigt. Another disadvantage of such pulp mills is their relative high fresh water requirement, for which a complex water treatment is required is. There are also facilities for waste liquor treatment and cleaning the wastewater needs.

Im allgemeinen sind solche Fabriken eine ernste Umweltbelastung. In general, such factories are a serious environmental burden.

Beim Verfahren nach P 3110 117.8 treten weder umweltschäd--liche Abwässer oder übelriechende Abluft auf und man benötigt nur einen Bruchteil als rentable Mindestkapäzität, auch ist der erforderliche Energieverbrauch klein. In the process according to P 3110 117.8, neither environmentally harmful substances occur Waste water or foul-smelling exhaust air and you only need a fraction of it profitable minimum capacity, also the required energy consumption is small.

All diese Vorzüge sind entscheidende Argumente für die Errichtung mikrobiologischer Zellstoffwerke auf mobilen Fahrzeugen und vorwiegend auf Wasserfahrzeugen.All these advantages are decisive arguments for the establishment microbiological pulp mills on mobile vehicles and mainly on watercraft.

Hierbei ist noch zu beachten, daß die für die Beschleunigung des mikrobiologischen Abbauprozesses erforderliche Wärme aus dem Abdampf oder aus dem Kühlwasser der Fahrzeugkraftanlage gewonnen werden kann. Als Antrieb für die Fertigungsmechanismen-kann gleichfalls die Fahrzeugkraftanlage verwendet werden.It should be noted here that the for the acceleration of the microbiological The heat required for the degradation process from the exhaust steam or from the cooling water of the vehicle power plant can be won. It can also act as a drive for the production mechanisms the vehicle power plant can be used.

Es ist von Vorteil, die für die Erzeugung erforderlichen Weißfäulepilze und Enzyme auf dem mobilen Fahrzeug oder Wasserfahrzeug selbst zu züchten.It is beneficial to have the white rot mushrooms required for production and to grow enzymes on the mobile vehicle or watercraft itself.
