Verfahren zum Erzeugen eines Gemisches aus Eisenerz und Schwelkoks

摘要

A granular coal and a pre-heated granular iron ore are loaded into a carbonising reactor in which temperatures between 800 and 1050 DEG C are produced by supplying oxygen-containing gas and by partial oxidation of the constituents of the coal. The granular solids are kept in the carbonising reactor in a fluidised system. Hot waste gas is guided to a solids separator from the upper region of the reactor. The granular iron ore is pre-heated with the hot waste gas and a hot, granular mixture of iron ore and semi-coke is drawn off as a product from the reactor and/or the separator. Said carbonising reactor can be embodied as a fluidised bed reactor or as a pneumatic transport route. The granular mixture of iron ore and semi-coke is suitable, for example, for a melting reduction process.
