Process for the production of molded metallurgical coke from coal briquettes

摘要

The process for the production of molded metallurgical coke from dried coal or fine coal mixtures with a low swelling index particularly highly volatile fine coal comprises mixing normal washed fine coal or fine coal mixtures of a grain size of from 0 to 10 mm and a swelling index of not more than 5 with a binder, pressing the mixture into briquettes, oxidizing the briquettes in a continuous material flow stream, and coking the oxidized briquettes continuously in an oven chamber by supplying indirectly and exhausting the coke oven gases with a temperature of 300 DEG to 1200 DEG C. The device for carrying out the process includes a vertically extending reactor housing having an oxidation chamber adjacent the top thereof with an indirectly heated vertical coking chamber directly below the oxidation chamber and with a cooling chamber directly below the coking chamber and including means for circulating heating gases into the coking chamber and then upwardly through the coking chamber and out adjacent the top of the coking chamber and into the oxidation chamber.
