Title:
鉄と、CO及びH2含有の粗製合成ガスとを同時に製造する方法
Document Type and Number:
Japanese Patent JP2012528246
Kind Code:
A
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.
