Description

Verfahren zum Herstellen von Wassergas in einer Schicht von feinkörnigem Brennstoff unter Aufwirbeln des Vergasungsgutes In dem Hauptpatent ¢37 970 ist ein Verfahren zur Herstellung von Wassergas in einer Schicht von feinkörnigem Brennstoff beschrieben, bei dem sowohl die Luft als auch der Wasserdampf derart von unten in den Gaserzeuger eingeblasen wird, daß das feinkörnige Gut in der ganzen Schichthöhe sich in einer auf und ab wirbelnden Bewegung befindet.A method for producing water-gas in a layer of fine-grained fuel with swirling of the gasification material in the main patent ¢ 37 970 a process for the preparation of water-gas in a layer of fine-grained fuel is described in which both the air and the water vapor to such from below in Gas generator is blown in that the fine-grained material is in an up and down swirling movement in the entire layer height.

Es wurde nun gefunden, daß man bei diesem Verfahren vorteilhaft während des Wassergasblasens in die von Dampf durchmischte glühende Kohle frischen Brennstoff, und zwar am zweckmäßigsten seitlich oder von unten, z. B. mit Hilfe einer Schnecke, einführt. Es ist zwar schon bekannt, durch Einführung von bituminöser Kohle oder durch Einblasen von flüssigen Kohlenwasserstoffen in glühende Kohle ein heizkräftiges Wassergas herzustellen. Das neue Verfahren bietet gegenüber dem Bekannten aber große Vorteile. So hat es sich gezeigt, da$ man im vorliegenden Falle bei vergleichsweise tieferen Temperaturen und unter Erzielung größerer .Ausbeuten ein Wassergas von höherem Heizwert als nach dem Verfahren des Hauptpatents erhält, da z. B. die durch Zersetzung des Bitumens der Kohle entstehenden Kohlenwasserstoffe, wie Äthylen, Propylen, Methan usw., nicht zerstört werden, sondern nahezu restlos im Wassergas enthalten sind. Als Brennstoff kann nicht zu feuchte Braunkohle oder auch Steinkohle, Preßtorf, Holzmehl usw. verwendet werden. Der Gehalt des Brennstoffs an flüchtigen organischen Substanzen, wie Bitumina, soll zweckmäßig möglichst hoch sein. Das frische Gut, das in die glühende bewegte Kohle eintritt und sich außerordentlich leicht einführen läßt, vermischt sich sofort mit der Kohle, so daß eine sehr gute und schnelle Wärmeübertragung und damit ein rascher Verlauf der Erzeugung des wertvollen Gases stattfindet, und gibt Teerdämpfe und allenfalls noch Wasserdampf ab, die durch die glühende Kohleschicht treten müssen. Hierbei zersetzen sich die Teerdämpfe unter Bildung von Äthylen, Propylen, Butylen und Methan oder bei sehr hoher Temperatur zu letzterem allein. An Stelle von Kohle können zur Erzielung einer größeren Ausbeute und zur Erhöhung des Heizwertes von Wassergas auch flüssige Brennstoffe, wie Teere, Öle, Mineralölrückstände, geschmolzener Asphalt usw., eingeführt werden. Das Verfahren gestattet einen außerordentlich hohen Durchsatz an Brennstoffen.It has now been found that this method is advantageous during of blowing water gas into the glowing coal mixed with steam, fresh fuel, and most expediently from the side or from below, z. B. with the help of a snail, introduces. Although it is already known by the introduction of bituminous coal or by injecting liquid hydrocarbons into glowing coal a powerful one To produce water gas. However, the new process offers great advantages compared to the familiar Advantages. It has been shown that in the present case one compares lower temperatures and achieving greater. Yields a water gas of higher calorific value than according to the method of the main patent, since z. B. the through Decomposition of the bitumen of the coal produced hydrocarbons, such as ethylene, Propylene, methane, etc., are not destroyed, but almost completely in the water gas are included. Lignite or hard coal that is not too moist can be used as fuel. Pressed peat, wood flour, etc. can be used. The volatile content of the fuel Organic substances, such as bitumen, should expediently be as high as possible. The fresh one It is good that it enters the glowing moving coal and is extraordinarily easy can be introduced, mixes immediately with the coal, so that a very good and fast Heat transfer and thus a rapid process for the generation of the valuable gas takes place, and gives off tar vapors and possibly even water vapor that through the have to step on the glowing layer of coal. Here the tar vapors decompose Formation of ethylene, propylene, butylene and methane or at very high temperatures to the latter alone. Instead of coal you can to achieve a greater yield and, to increase the calorific value of water gas, also liquid fuels, such as tars, oils, mineral oil residues, molten asphalt, etc., are introduced. The process allows an extremely high throughput of fuels.

Beispiel In einem Gaserzeuger von 4 qm .Schachtquerschnitt, mit dem Wassergas nach dem Verfahren des Hauptpatents hergestellt wird, lagert eine 150 cm hohe glühende Grudeschicht von 7oo° C. Die Grude wird bis -et-,Ra iioo° C heißgeblasen, wobei die Kohlehöhe auf rd. r i o cm sinkt. Es werden nun statt Luft während etwa 5 Minuten rd. 400 kg Dampf und rd. gookg Braunkohle mit rd. io%Wasser und rd. io 0/0 Teergehalt eingeführt. In dieser Zeit werden 550 cbm Wassergas geblasen, wobei die Kohlehöhe auf rd. 130 cm ansteigt. Ohne Braunkohleeinführung werden nur rd. 400 cbm Wassergas erhalten. Das Gas hatte anfangs folgende Zusammensetzung: 6,3 % C02, 34,9 % CO, 42,6 % H2, 2,o % CH" i4,:2 % N, und als die Temperatur im Gaserzeuger auf rd, 8oo° C gesunken war: 23,4 % C02, 3,2 % schwere KohlenwasserstOffe, 21 % CO, 38,6 % H2, 5,6 % CH4 und 8,2 % N2.Example In a gas generator of 4 square meters. Shaft cross-section, with which water gas is produced according to the process of the main patent, a 150 cm high glowing soil layer of 700 ° C is stored drops to around rio cm. Instead of air, around 400 kg of steam and around cooked brown coal with around 10% water and around 10% tar content are now introduced for about 5 minutes. During this time, 550 cbm of water gas are blown, the coal height increasing to around 130 cm. Without the introduction of lignite, only around 400 cbm of water gas is obtained. The gas initially had the following composition: 6.3% CO 2, 34.9% CO, 42.6% H2, 2.0% CH "i4,: 2% N, and the temperature in the gas generator was around 800 ° C decreased: 23.4% C02, 3.2% heavy hydrocarbons, 21% CO, 38.6% H2, 5.6% CH4 and 8.2% N2.

Bei Arbeiten ohne Braunkohlezusatz erhält man bei 8oo° beim Wassergasblasen ein Gas von der Zusammensetzung: 28 0/0 C02, 4 0/0 CO, 6 1 0/u H2, i % CH4, 6 % N,.When working without the addition of lignite, a gas with the composition: 28 % CO 2, 4 0/0 CO, 6 1 0 / u H2, 1% CH4, 6% N, is obtained at 800 ° when blowing water.
