Embodiment Construction

[0010] Typically, the blast furnace is charged with iron ore and coke in layers from above, the charge slides down into the always hotter region of the furnace, and oxygen is injected in the lower part of the furnace. Part of the carbon-containing reducing agent is thus combusted to form CO that rises to the iron ore pile 2 and CO. Iron ore is reduced to metallic iron by rising gases and hot carbonaceous reducing agents. According to the invention, an additional amount of carbon-containing reducing agent is also fed to the blast furnace compared to pure iron production. To maximize raw synthesis gas production, this additional volume can be delivered as coke, coal, petroleum, plastics, natural gas, recycle gas, coke oven gas or waste gas. The amount of oxygen matches the amount of fuel and is also greater than that required for pure iron production. According to the invention, the blast furnace process is carried out in such a way that the blast furnace gas already contains...

Abstract

The invention relates to a method for simultaneously producing iron and a crude syngas containing CO and H2 by means of a blast furnace that is charged with iron ore and carbon-containing reducing agents. The amount of carbon-containing reducing agents fed to the blast furnace is greater than the amount of fuel required for producing the iron. Technically pure oxygen is fed into the blast furnace for the blast furnace process and for producing the crude syngas. In addition, CO2 and / or steam are fed to the blast furnace in order to control the ratio between CO and H2 in the crude syngas discharged from the blast furnace as top gas and / or moderate the temperature at which the oxygen is injected.

Description

technical field [0001] The present invention relates to a method for simultaneously producing iron and containing CO and H 2 method of crude synthesis gas. Background technique [0002] Syngas is a gas mixture which is used in synthesis reactions and is mainly composed of CO and H 2 composition. For some CO / H 2 - Combinations to form specific names based on their origin or their application, eg, water gas, pyrolysis gas, methanol-synthesis gas or oxo gas. Syngas can be used as a feedstock mixture to produce liquid power fuels, for example, it can be used to produce diesel power fuels in the Fischer-Tropsch process. Gasoline power fuels can be produced according to the MTG process (Methanol-to-Gasoline Technology), in which synthesis gas is first converted into methanol, which is then reconverted into gasoline in a further process step. [0003] In principle all carbonaceous materials can be used for the production of synthesis gas. This includes not only the fossil fue...
