Combination method and device for gasifying coal and for reducing metal ores

Claim 1

Combination method for the gasification of coal and the reduction of metal ores which comprises subjecting comminuted coal to hydrogenation in a hydrogenation zone in the presence of added hydrogen to produce gaseous constituents containing hydrocarbons and unreacted hydrogen gas and a non-vaporous residual coke component, releasing the gaseous constituents from the hydrogenation zone, discharging the coke component from the hydrogenation zone, subjecting said coke component to steam gasification in a steam gasification zone in the presence of added steam to produce a steam gasification gas containing H 2 , CO and CO 2 and an ash residue, passing said steam gasification gas in contact with a metal ore in a reduction zone to effect reduction of the ore, releasing spent gas containing CO after contact with said ore from the reduction zone, passing said spent gas to a conversion zone to react said CO with steam to produce H 2 and CO 2 , passing the thus converted gas containing H 2 and CO 2 to a scrubbing zone to effect removal of CO 2 , and feeding the converted gas containing H 2 after removal of CO 2 as well as a hydrogen containing gas separated from said released gaseous constituents, to the hydrogenation zone.
