ABSTRACT:
A method of producing form coke that is coke having pieces of substantially identical form using a heated shaft furnace comprises mixing fine coke with a caking coal and pressing the mixture at temperatures at which the mixture is plastic in order to form briquettes. The briquettes are permitted to harden and degasify and thereafter they are exposed to a high temperature after hardening for example to a temperature of from 400.degree. to 900.degree. C from 60 to 120 minutes. Thereafter the briquettes are cooled. A first mixing substance is prepared by permitting a fine coal to fall in a non-compressed stream in the shaft furnace while heat is transferred thereto substantially by radiation.
