Abstract:
1. A method for generating a gas containing hydrogen and carbon monoxide, as a raw material for chemical utilization in synthesis processes based on export gas from a metallurgical process, the method comprising: adding at least one of water and water vapor to the metallurgical process thereby affecting the quantity ratio of H obtaining the export gas from top gas from a blast furnace or a reduction shaft or from offgas from a fluidized bed reactor or from excess gas from a melt-down gasifier or from mixtures of these gases; subjecting at least part of the export gas to CO conversion in a transformation reactor with the addition of water vapor from a steam generator; using the converted at least part of the export gas as a crude synthesis gas with a defined quantity ratio of H storing a further part of the export gas in a gasholder for the purpose of compensating fluctuations in at least one of quantity and in calorific value in the export gas; and generating the water vapor in the steam generator by means of the combustion of the at least further part of the export gas.
