Description
Verfahren zur Gewinnung schwefelfreien Gases bei der Kohlendestillation. Es ist bekannt, den Gaskohlen vor der Entgasung Metalloxyde in Gestalt von Eisenerzen oder Kalk bzw. Kalkhydrat in verschiedenen Mischungsverhältnissen zuzusetzen, um schwefelfreies Gas zu erhalten. Diese Zusätze haben nicht befriedigt; sie bewirken zwar eine Entschwefelung, andererseits beeinflussen sie daneben aber die Güte des anfallenden Kokses nachteilig, indem sie, ähnlich wie ein entsprechender Aschegehalt rler Kohle, den Koks minderwertig machen.Process for obtaining sulfur-free gas from coal distillation. It is known that metal oxides in the form of iron ores are added to the gas coals prior to degassing or to add lime or hydrated lime in various proportions to to obtain sulfur-free gas. These additives have not been satisfactory; they cause Although a desulphurisation, on the other hand they also influence the quality of the accruing coke disadvantageous in that they, similar to a corresponding ash content rler coal that make coke inferior.
Erfindungsgemäß wurde festgestellt, daß Walzensinter, wie er z. B. in den Eisenwalzwerken oder Hammerwerken entfällt, als Zusatz zur Gaskohle diese Nachteile nicht nach sich zieht. Der Walzensinter ist frei von aschebildenden Bestandteilen; er besteht aus der Sauerstoffverbindung Fe304, die beim Vergasungsprozeß in Wechselwirkung mit der Kohle folgende Umsetzungen erleidet: r. Fe., O,, + 4 C - 3 Fe + .4 CO, z. Fe -{- S - Fe S.According to the invention it was found that roller sintering, as it is, for. B. in the iron rolling mills or hammer mills, it is not used as an additive to gas coal Does not entail disadvantages. The roller sinter is free from ash-forming components; it consists of the oxygen compound Fe304, which interacts during the gasification process undergoes the following reactions with the coal: r. Fe., O ,, + 4 C - 3 Fe +. 4 CO, e.g. Fe - {- S - Fe S.
Der Zusatz von Walzensinter ist deshalb so außerordentlich bedeutungsvoll, weil er nicht mit porenfüllenden Bestandteilen, wie Gangarten, Kalk usw., belastet ist und die Reduktion durch CO-Gasbildung stark porenbildend auf den Koksteig wirkt, während das Eisenskelett die Porenwände verstärkt, wodurch der Koks fest und großstöckig wird.The addition of roller sinter is therefore extremely important, because it is not contaminated with pore-filling components such as gait, lime, etc. and the reduction through CO gas formation has a strong pore-forming effect on the coke dough, while the iron skeleton strengthens the pore walls, making the coke firm and tall will.
