  • Patent number: 4158550
    Abstract: A method of producing blast furnace coke from bituminous coals, particularly coals having poor coking capacities in which the coal to be carbonized is ground, predried or preheated, mixed with binders, compressed or formed into briquets having small mechanical resistances and charged into oven chambers, is characterized by fine coals or fine coal mixtures having a swelling index in mixture according to DIN 51741, smaller than 7, and preferably, below 6, and comprising more than 50% of poorly or non-baking coal having a content of volatile matter in excess of 30% or less than 20% which coals or coal mixtures are ground up to attain a surface per unit mass, according to DIN 66145, of from 400 cm.sup.2 to 1200 cm.sup.2 per gram, with from 3% to 8% by weight of organic binders, compressing the mixture to form it into a briquet at a temperature range of from 70.degree. C. to 300.degree. C. and charging the compressed briquet into the oven chambers without substantial intermediate cooling in order to carbonize it.
