Die Erfindung betrifft ein Verfahren zum rkoken von Kohle unter gleichzeitiger Verbdung von metalloxydischen Stoffen, z. B. im Flugstaub der Gichtgase, den pulverigen senoxyden, die nach der Extraktion der hwefelkicsabbrände zurückbleiben : (sogen, rple ore).The invention relates to a method for rkoken coal with simultaneous connection of metal oxide substances, such. B. in the airborne dust of the furnace gases, the powdery senoxides, which after the extraction of the hwefelkics burns remain: (so-called, rple ore).
Dieser Zusatz von metalloxydischen Stoffen 'irde bisher verwendet, ohne etwa festzu- :llen, welche Einflüsse z. B. auf die BiI-ing der Nebenprodukte ausgeübt werden IJnnten.This addition of metal-oxide substances has so far been used without : llen, which influences z. B. be exercised on the formation of the by-products Inside.
Die Erfindung beruht auf der Feststellung, durch den Zusatz dieser Stoffe; in den
[ir die Güte des Koks zulässigen Grenzen hon die Ausbeute an Ammoniak sehr benträchtigt
wird, und zwar in dem Maße, ie die Stoffe reduzierbare Metalloxyde (voriegend
Fe2 O3) führen.
Ein Zusatz von. nur io Prozent an purple e z. B. zu einer gasreichen Kokskohle verindert
die Ausbeute an Ammoniak um ί,ΐ Prozent, d. h. statt 0,90 Prozent schwefelures
Ammoniak wird nur 0,796 Prozent er-•acht. j.The invention is based on the finding through the addition of these substances; within the limits admissible for the quality of the coke, the yield of ammonia is greatly impaired, namely to the extent that the substances contain reducible metal oxides (predominantly Fe 2 O 3 ).
An addition of. only 10 percent of purple e z. B. to a gas-rich coking coal reduces the ammonia yield by ί.ΐ percent, ie instead of 0.90 percent sulphurous ammonia, only 0.796 percent is • used. j.
Bei Zusatz von 10 Prozent Gichtstaub erlab sich statt 0,90 Prozent nur 0,720 Prozent :hwefelsaures Ammoniak. : With the addition of 10 percent gout dust, instead of 0.90 percent, only 0.720 percent is obtained: sulfuric acid ammonia. :
Die Erfindung bezweckt, eine Verringerung |er Ausbeute an Ammoniak zu verhindern, '!ine daß der Zusatz der metalloxydischen l'toffe aufgegeben wird. Demgemäß' werden Pie metalloxydischen Stoffe vor dem Zusatz !'ur Kohle von ihrem die Zersetzung des Ammoniaks bedingenden Sauerstoff befreit, d. h. sie werden vor ihrem Zusatz reduziert. The aim of the invention is to prevent a reduction in the yield of ammonia, in that the addition of metal oxide substances is abandoned. Accordingly 'Pie are metal oxide substances before the addition ! 'ur coal is freed of the oxygen which causes the decomposition of ammonia, that is, they are reduced before they are added.
Dieses hat zur Folge, daß z. B. dieselbe Kohle, die für die obigen Beispiele verwendet wurde, mit einem Zusatz von 10 Prozent reduziertem Gichtgasstaub bezw. purple ore 0,929 Prozent schwefelsaures Ammoniak ergab.This has the consequence that z. B. the same charcoal used for the above examples was, respectively, with an addition of 10 percent reduced gout gas dust. purple ore yielded 0.929 percent ammonia sulfur.
Es ist bekannt, metalloxydhaltige Stoffe, z. B. Gichtstaub, vor dem Zusatz zur Kohle unter Luftabschluß zu erhitzen, wobei der Gichtstaub nur von einem Teil seines Sauerstoffes befreit werden sollte. Von diesem bekannten Verfahren unterscheidet sich das vorliegende dadurch, daß die metalloxydhaltigen Stoffe von ihrem gesamten Sauerstoff befreit werden, daß also die Metalloxyde vorher vollständig zu Metallschwamm reduziert werden." Dies ist notwendig, um jegliche Beeinträchtigung der Ammoniakausbeute zu verhüten.It is known to use metal oxide-containing substances such. B. gout dust, before adding to coal to be heated in the absence of air, the gout dust from only a part of its oxygen should be freed. The present one differs from this known method in that the metal oxide-containing Substances are freed from all their oxygen, so that the metal oxides previously completely to metal sponge This is necessary to avoid any impairment of the ammonia yield to prevent.
