Abstract: A process for processing metal ore includes: reducing a metal ore, particularly a metallic oxide, in a blast furnace shaft; producing furnace gas containing CO2, in the blast furnace shaft; discharging the furnace gas from the blast furnace shaft; directing at least a portion of the furnace gas directly or indirectly into a CO2-converter; and converting the CO2 contained in the furnace gas into an aerosol consisting of a carrier gas and C-particles in the CO2-converter in the presence of a stoichiometric surplus of C; directing at least a first portion of the aerosol from the CO2-converter into the blast furnace shaft; and introducing H2O into the blast furnace shaft.

The speed of reduction of the metal ore is thus increased, and it is possible to increase either the throughput capacity of the blast furnace or to reduce the size of the blast furnace.

Abstract: A method producing synthetic hydrocarbons includes producing synthesis gas. An initial step, carbon or a mixture of carbon and hydrogen is brought into contact with water at a temperature of 800-1700° C. The synthesis gas is converted into synthetic functionalised and/or non-functionalised hydrocarbons by means of a Fischer Tropsch process wherein it is brought into contact with a suitable catalyst, and wherein water in which a portion of the synthetic hydrocarbons is dissolved results as a by-product. At least a portion of the water that is produced as a by-product is supplied to the initial step. The hydrocarbons that are dissolved in the water decompose into particle-like carbon and hydrogen at the high temperature. The carbon is converted into CO in the presence of water and at a high temperature and forms a portion of the synthesis gas that is produced. In this way, a costly process for cleaning half of the water that is produced as a by-product is avoided.
