摘要
The invention relates to a process for producing pig iron or liquid primary steel products in a blast furnace, CO2 being substantially removed from at least a partial stream of a top gas emerging from a reduction shaft furnace (1), and this partial stream if appropriate being heated and being introduced into the blast furnace as reduction gas, and to a plant for carrying out this process, the top gas being introduced into the lower region of the blast-furnace shaft. This measure results in an improved energy balance and improved process management compared to the prior art.
