Abstract: The coke forms are produced in four stages, each constituted by a respective oven chamber, and in which the briquets are, respectively, preheated, dehydrated or dried, carbonized and cooled. Hot gas circuits are provided, in which the hot gas is composed substantially of burnt lean gas of the carbonization, and, for each stage, the hot gases are recirculated in a separate respective circuit. In the preheating, dehydrating and carbonization stages, the hot gases are heated and produced, or supplemented, in a respective separate combustion chamber with the recirculating hot gas in the carbonization stage being supplemented with cooled lean gas from this stage. The recirculating hot gases are dedusted separately in a dust settling chamber in which their flow velocity is reduced to approximately 0.2 to 2.0 m/sec, with the dust being collected.

Abstract: An apparatus for producing form coke that is coke having pieces of substantially identical form comprises 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.

Abstract: A method of removing ash components from coals, particularly high-ash content coals, comprises grinding the coal into ground particles and suspending the ground coals in an aqueous alkali carbonate solution. The solution is maintained in a reactor for 45 to 120 minutes at a temperature range of from 250.degree. to 280.degree. C and under a pressure of from 50 to 80 atm in order to cause the CO.sub.2 to be set free by dissociation. The CO.sub.2 is discharged from the reactor by directing an inert gas stream through the reactor and discharging the CO.sub.2 with the gas stream. The suspension is stirred and agitated at elevated temperatures and increased pressures in order to fuse the ashes. The aqueous solution containing the dissolved ash components is then separated from the coal. The removed carbon dioxide is introduced into a solution for reforming the alkali carbonate in order to cause the contents of the solution to become insoluble and separated and the alkali solution to become regenerated.
