Reformer gas-based reducing method with reduced NOx emission

摘要

In a process and apparatus for the reduction of metal oxides (3) to form metalized material by contact with hot reducing gas, which is produced at least partially by catalytic reformation of a mixture of a gas containing carbon dioxide (CO2) and/or steam (H2O) with gaseous hydrocarbons, the heat for the endothermal reformation processes which take place during the reformation is provided at least partially by the combustion of a fuel gas.
