Abstract: The present blast furnace and method for operating a blast furnace are able to reduce CO2 production and the amount of applied additives and heating material. The method for metal production of metal ores comprising the following steps: reducing a metal ore, particularly a metal oxide, and thereby producing furnace gas containing CO2 in a blast furnace shaft; discharging the furnace gas from the blast furnace shaft; directing at least a portion of the furnace gas into a CO2 converter and reducing the CO2 in the furnace gas into CO; directing at least a portion of the CO from the CO2 converter into the blast furnace shaft. The method produces CO as a gaseous reduction agent which may be easily introduced into the blast furnace shaft. Further, a blast furnace for metal production by reducing a metal ore designed for operating according to the method is described.

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. By virtue of the reaction C+H2O?CO2+2H, nascent hydrogen is produced in the blast furnace which causes rapid reduction of the metal ore. 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 process and an apparatus for converting carbon dioxide CO2 into carbon monoxide CO using hydrocarbons are described. In further embodiments, processes and apparatuses for generating synthesis gas and processes and apparatuses for converting synthesis gas into synthetic functionalised and/or non-functionalised hydrocarbons using CO2 and hydrocarbons are described. The processes and apparatuses are adapted to convert CO2 emitted by industrial processes, and thus the amount of carbon dioxide emitted into the atmosphere may be reduced.

Abstract: A method for producing ¾-rich synthesis gas comprises the following steps: decomposing a hydrocarbon-containing fluid into an H2/C-aerosol in a first hydrocarbon converter by supplying energy which is at least partly provided in the form of heat; introducing at least a first stream of the H2/C-aerosol into a first sub-process which comprises the following steps: directing at least a part of the H2/C-aerosol from the first hydrocarbon converter into a first C-converter; introducing CO2 into the first C-converter and mixing the CO2 with the H2/C-aerosol introduced into the first C-converter; converting the mixture of H2/C-aerosol and CO2 into a synthesis gas at a temperature of 800 to 1700° C.; mixing additional H2 with the synthesis gas for the production of H2-rich synthesis gas.

Abstract: A method and an apparatus for generating synthesis gas using hydrocarbons and water are described. In further embodiments of the method and the apparatus, synthesis gases having any desired CO/hydrogen ratio and/or synthetic functionalized and/or non-functionalized hydrocarbons are generated. With this method, a hydrocarbon containing fluid may be transformed into a synthesis gas having variable hydrogen content without generating significant amounts of CO2. Further, hydrogen and different forms of carbon may be obtained as by-products.
