Patent ID: RE39536

Claim:
Method for the production of liquid metal from metal carriers ( 3 ) in a melter gasifier ( 1 ) in which with supply of a carbon-containing material at least partially formed of fine coal ( 16 ) and coal dust ( 13 ) and with supply of oxygen or oxygen-containing gas the metal carriers are melted in a bed ( 4 ) of the carbon-containing material with the simultaneous formation of a reducing gas, optionally upon previous final reduction, characterized in that fine coal ( 16 ) and coal dust ( 13 ) are mixed with hot bitumen ( 20 ) and subsequently are cold-briquetted, and that the briquettes ( 25 ) thus formed are charged to the melter gasifier ( 1 ) and in the melter gasifier ( 1 ) are subjected to shock-heating, and wherein the charged carbon-containing material is dried and during and/or after drying of the carbon-containing material, the fine coal ( 16 ) and coal dust ( 13 ) are separated from lumpy carbon-containing material and further treated while hot.
