Abstract

Synthesis gas mixts. contg. CO and H2 in volume ratio 1:2 are made by gasification of coal or coke, using oxygen from electrolysis of water, the hydrogen obtd. to the same time being added to the produce gas after purification Excess current from power stations at off-peak periods can be used to produce the O2 and H2 at low cost, with storage in the pipe-line system. Special plant for conversion of part of the CO to CO2 in order to obtain the correct CO/H2 ratio is avoided, and consumption of coal reduced.

Description

Betr.: TreibstoffsynthesegaserzeugeranlageRe: fuel synthesis gas generating plant

eit langem bekannt sind die Benzinsynthese nach Fischer-Tropsch, die Drucksauerstoffvergasung von Kohle oder Koks in verschiedenen Verfahren, sowie die Zerlegung von Wasser in Sauerstoff und Wasserstoff mittels elektrischen Stromes. Nachstehende Beschreibung zeigt, wie man mit einer geeigneten Kombination dieser Verfahren, bezw. von Teilen derselben einige Nachteile der vorhandenen Verfahren vermeiden und eir besonderes umweltfreundliches und preisgünstiges Treibstoffherstellungsverfahren schaffen kann. er besondere Vorteil der Kombination erhellt aus Folgendem.The gasoline synthesis according to Fischer-Tropsch, the Pressurized oxygen gasification of coal or coke in various processes, as well as the Decomposition of water into oxygen and hydrogen by means of an electric current. The description below shows how to come up with a suitable combination of these Procedure, respectively. some of the disadvantages of the existing methods avoid and use a particularly environmentally friendly and inexpensive fuel production process can create. The particular advantage of the combination is evident from the following.

Um Benzin erzeugen zu können, braucht man ein solches Synthesegas, das etwa ein Volumenverhältnis CO : H wie 1 : 2 aufweist. Vorgeschlagen wird wie bisher üblich 2zunächst die Herstellunvon Generatorgas, welches je nach Herstellungsart ein CO : H2 -verhältnis von etwa 1 : 1 aufweist und zwar aus Kohle oder Koks mit Hilfe von sauerstoff gewissen Überdruckes, dem in erster Linie zur Beherrschung der Temperaturen Wasserdampf beigemengt ist.In order to be able to produce gasoline, one needs such a synthesis gas, which has a volume ratio of CO: H such as 1: 2. It is suggested how Up to now, the production of generator gas has been customary, which depends on the type of production has a CO: H2 ratio of about 1: 1 from coal or coke with Help of oxygen of a certain overpressure, primarily for control water vapor is added to the temperatures.

Erfindungsgemass soll der Sauerstoff nicht wie bisher üblich aus einer Luftzerlegungsanlage bezogen werden, sondern durch Zerlegung von Wasser durch elektrischen Strom. Dabei soll beispielsweise Überschussstrom aus Zeiten der Niedrigbelastung von Elektrizitatskraftwerken verwendet werden.According to the invention, the oxygen should not, as was previously the case, from a Air separation plant can be obtained, but by separating water by electrical Current. For example, excess electricity from times of low load should be used used by electric power plants.

Die Kraftwerke müssen sowieso den ganzen Tag laufen. Ihre Abschreibungs- und Beaienungskosten sind bereits aus der normalen Elektrizitatserzeugung gedeckt, so dass neben gewissem apparativem Aufwand wesentliche Herstellungskosten fur Sauerstoff und Wasserstoff nur noch aus dem Mehrverbrauch des Kraftwerkes an Brennstoff resultieren, der aber insbesondere bei Atomkraftwerken ziemlich billig ist.The power plants have to run all day anyway. Your depreciation and maintenance costs are already covered by normal electricity generation, so that, in addition to a certain outlay in terms of equipment, there are significant manufacturing costs for oxygen and hydrogen only result from the additional fuel consumption of the power plant, but it is quite cheap, especially in the case of nuclear power plants.

Die durch die Wasserzerlegung gewonnenen Gase O und H können in langen Rohrsystemen gespeichert werde, evtl. auf dem Wege vom Kraftwerk zur Syntheseanlage. Dort wird man auch die Generatorgasanlage mit ihren Nebenanlagen aufstellen, z.B. CO -wäsche. Auf jeden Fall ist ferner vor der Synthese eini Gasentschwefelung erforderlich.The gases O and H obtained through the decomposition of water can be used for a long time Pipe systems are stored, possibly on the way from the power plant to the synthesis plant. The generator gas system with its ancillary systems will also be set up there, e.g. CO washing. In any case, gas desulphurization is also required before the synthesis.

Üblich ist es bisher für Synthesen das Generatorgas in einer Konversionsanlage so umzuwandeln, dass es die für die Synthese nötige Zusammensetzung erhalt, also CO : H wie 1 : 2. Dabei wird eine besondere Anlage benötigt, de unter anderem eine gewisse Menge Co in Co2umwandelt, was jedoch hier aus Gründen der Kohleersparnis vermieden werden soll.The generator gas in a conversion plant has been customary for syntheses up to now to convert in such a way that it receives the composition necessary for the synthesis, i.e. CO: H as 1: 2. A special system is required, including one converts a certain amount of Co into Co2, but here for reasons of coal saving should be avoided.

In einfachster Weise soll stattdessen erfindungsgemäss das Generatorgas in Synthesegas umgewandelt werden, indem man den Wasserstoff aus der elektrischen Wasserzerlegung im Wesentlichen unter Umgehung der Generatoranlage direkt dem erzeugten Generatorgas nach seiner Reinigung zufügt.Instead, according to the invention, the generator gas is to be used in the simplest manner can be converted into synthesis gas by taking the hydrogen from the electrical Water decomposition essentially bypassing the generator system directly to the generated one Adding generator gas after it has been cleaned.

Gegenüber den bisherigen Verfanren stellt diese Arbeitsweise eine sehr grosse Vereinfachung dar, insbesondere auch, weil die einzelnen Anlageteile der Gaserzeugung una Reinigung geringere Abmessurgen erfordern. @berschüsse von Wasserstoff wie auch das Restgas aus der spateren Syntnesc Konnen zu Heizzwecken verwendet, bezw. als Zusatz zum Dampf fur den Generatorbetrieb verwendet werden.Compared to the previous procedures, this way of working represents a very great simplification, especially because the individual parts of the system gas generation and cleaning require smaller dimensions. @ surpluses of Hydrogen as well as the residual gas from the later Syntnesc can be used for heating purposes used, respectively. can be used as an additive to steam for generator operation.

Bei dem Sauerstoffgeneratorverfahren kommt das die Umwelt verschmutzende Aufheizen der ublicherweise verwendeten Wassergaserzeuger mit Luftdurchblasen in die Atmosphare vollkommen in Fortfall, wobei zugleich hochwertiger Generatorkoks gespart wird.With the oxygen generator process comes what is polluting the environment Heating of the commonly used water gas generator with air blowing in the atmosphere completely in decline, while at the same time high quality generator coke is saved.

Der Rest der Anlage mit Kontaktofen, Aktivkohleabscheidung des Benzins usw. braucht nier nicht naher beschrieben zu werden, da er von den Fischer-Tropsch Anlagen seit 50 Jahren bekannt istThe rest of the plant with contact furnace, activated carbon separation of the gasoline etc. need not be described in more detail, since it is from the Fischer-Tropsch Plants has been known for 50 years
