Patent ·
OSTI ID:5496738
A method of producing form coke, particularty metallurgical coke for a blast furnace, comprises mixing at least two finely ground coal components, a non-caking component and a caking component, and heating the mixture at temperatures corresponding approximately to the softening point of the caking coal component. The caking component is a bituminous coal, and the non-caking component comprises an oil coke containing little volatile matter. The heated mixture is carbonized and pressed to form a briquetted form coke, and the form coke is subsequently hardened.
